I've learned sooooo much misinformation from stylists. I think it's because their education heavily relies on how much the stylists who trained them know ..and often it's not much .
@@226iamacake thankfully that's not the case in Germany, here it's a full 3 year trainee programm for hair styling (+basics of make up and nail design) and the people i worked with were all extremely talented and educated in their craft. still no consensus on hair drying 😅
@@PhiloishnessThey may be educated in hair styling and colour processing but not in trichology. It's like that anywhere. They don't really learn about or keep up with the science of hair and scalp care and health. Hairstyling is a vocational/craft kind of educational route not science.
In my experience all my stylists just go by rules of thumb that they have heard somewhere. Even had one say that shampoos with mint reduced hair loss by 30%. I don't even know what to say that. The industry is full of broscience even though they're all educated. In Denmark it's a 1 year education with 3 years of apprenticeship (or something like that), but I suppose they don't have a lot of motivation or opportunity to keep up with the science.
She was incorrect about one thing though. It’s driving me a little nuts lol. She said that bleached hair retains moisturizing ingredients and water easily, it takes longer to dry…nope. It’s actually hair that absorbs moisture quickly, but doesn’t easily retain those nutrients. It’s called high porosity. On the other side of the spectrum, I have low porosity and I have hair that is slow to absorb. It’s harder to get those nutrients in, but once I do it STAYS. I’m obsessed with haircare, I know she was spreading at least this bit of misinformation. I explained in a comment on the video (not a reply) why.
i can't believe michelle said she hates hydrogen bonds and that she thinks hydrogen should stop bonding to things and just stay in the sun where it belongs 😮
My entire life I have blow dried my hair (even as a kid). Ppl always found my hair healthy, and at the same time said “blowdry is bad for your hair”. Thanks for explaining it
@@haehaev blow drying smooths the cuticle, it makes it look and feel healthier but heat damage has little to do with shine, and actually just makes the hair physically weaker
fr, my circadian rhythm has been ruined since I started staying up until like 3AM to study for finals. Now that exams are over, my body refuses to sleep and my mind prochrastinates the night away...😩
Water is a curly girl's main styling product and heat helps set the shape. I always figured blow drying my hair did me more good than air drying because my scalp gets oilier quicker if I air dry.
i heard as a good rule of thumb that if your hair isnt completely dry after 2 hours of air drying you should blow dry. drying your hair is what sets the hydrogen bonds in place, but the heat makes it happen faster because it evaporates water faster and allows the air to carry more moisture away
By the way, I love that your videos aren't that heavily gender-coded. As a man with awesome long hair, I vibe a lot better with your style of video than many others :) beauty is for everyone. Stay crispy!
It's such a huge pain in the butt having to translate ounces to millilitres all the time. And inches to cm and lbs to kg. Not to mention miles to km. America needs to switch!
@@SchlichteTovenAs an American, I can tell you it's never gonna happen. We don't like change here! Does it make more sense? Is it easier and more logical? We don't care. 😂
okay, fellow Canadian here, and I agree except I downright refuse to ever use cm to describe my amab partner’s package. It feels so wrong so I will never do that. That said, I’m otherwise impartial lmao
I figured I would absorb the metric system growing up. I did not, even do close to Canada. But I’m trying to transition now, I watch so many non US creators & it’s frustrating to be so globally stupid. “Oh my country measures things in body parts and old timey nonsense, you don’t use the worst measurement system of all time???” We sound like dunces from a fairy tale country…
Can't explain how satisfying it is to hear you cover all factors not just a sweeping "X is better than Z, done." - Also appreciate that that you addressed/re-addressed the article about airdrying being more damaging, thank you for sharing!!
Would you consider doing a video on hair washing technique too? I'm particularly interested in if hair scrubbers are worth it or do more harm than good!
She did, but I don't think she mentioned hair scrubbers. I don't think they're anywhere near necessary, but if you like them, they're probably fine. Just don't scrub in circles, or irritate your scalp.
I had to google what hair scrubber is (know it as scalp massager - loose translation as I never spoke about it in English) ... but: I had some issues with stress damaging my hair and worked with trichologist on that: she recommended using device like that to massage your scalp, but not while washing my hair - just as a massager to use while watching movie or something. I never asked her if I can/should use it during hair wash - it just never occurred to me as a possibility and she never used it on my head while washing my hair. In general: our scalps have a lot of nerves and massaging it is good for hair grow. Not necessary by any device, you can use your fingers (or your friends or partner as being massaged by someone else is nice in general - at least for me)
I have no research I can quote on this, so take this with a grain of salt. From my understanding, a scalp brush/massager/shampoo brush (whatever you call it) is not necessary for the average person. Most people don’t need to add more agitation to their scalp as their fingertips are more than enough to massage shampoo in properly. However, I have seen them be beneficial for at least two groups of people: people who need accessibility devices and people who have super long nails. Long nails are especially hard to keep damage free when wet (same concept as water making hair more fragile and this more susceptible to damage), so using a device to scrub your scalp, not your fingers to scrub, reduces the likelihood of damaging your nails. If someone has chronic pain in their hands/fingers or another kind of hand/finger-related disability, it makes it very difficult to properly scrub the scalp. Speaking from experience, it is very easy to get buildup on the scalp that is almost impossible to remove without much more time and energy than is possible to give when already doing something else that is very draining (showering is often very difficult for those of us with disabilities, so anything to make it easier and less exhausting - or even dangerous! - is a very welcome addition.) So really, I think the average person doesn’t need to at all. If you want to ensure you are cleaning your scalp enough, I would personally just shampoo at least twice *if* once isn’t enough and your scalp still feels a little gross.
My electric scalp massager helps me get rid of build-up from conditioner on my scalp, which helps me reduce dandruff and gives my hair more volume (I have fine hair). I wouldn't use it daily, though, as it can irritate the scalp when used too vigorously. I've also read that scalp massages help increase blood circulation which can help with hair regrowth. So it's like usual: Everything is good in moderation.
A hair stylist in Sydney who I follow on Instagram recently posted about a "bleach-free" lightener for hair (aka doesn't use hydrogen peroxide but is definitely still a type of bleach) and how it was a "damage-free" way to lighten hair. I was so disappointed to see him post something like that because he's usually super upfront about the damage of colouring hair. There is literally no way to lighten hair that isn't extremely damaging, you simply cannot obliterate the melanin in someone's hair without causing damage and I don't think it helps to mislead people into thinking that you can. It just sets people up for disappointment and confusion in caring for their processed hair. P.S. I just pre-ordered your book! Can't wait to put it on my "pretty books" bookshelf that I put all of my aesthetically pleasing books on.
It either damages the hair, or it won’t work! Recently I had a hair stylist use a “bleach-free” lightener on me- and she didn’t tell me beforehand. My bleached ends looked so much lighter than the bleach-free roots even though she left it on a long time 😭
I know it's very damaging to hair but I bleached mine years ago and it didn't look damaged. As long as it looked healthy that was good enough for me lol
What about photobleaching? I have naturally blonde hair which gets lighter during the summer. Of course the effect is not very strong nor fast especially as I don't sunbathe. Or is it just a matter of light hair getting damaged by UV, while dark hair doesn't? Just like darker skin doesn't get as easily damaged by the sun as light skin.
@@ninjal7588 for what its worth my dark hair definitely gets bleached by the sun in summer, my hair is very dark brown/black and by the end of summer it's a deep chocolatey brown with a lot of red tones in it! so i think it happens to most hair colours maybe
@@ninjal7588 hair photo bleaching can happen to any hair color. It’s definitely damaging and makes your hair a little dryer, but is nowhere near as bad as bleach. It does depend on your life lifestyle though. I took a summer in Florida one year and my hair was so damaged because I didn’t really take care of it while also constantly being in the sun that it was light brown, even though my hair is naturally dark brown. It felt so crunchy.
4:22-4:37 90°C is 194°F. (The temperature is close to boiling water when the water inside the hair will evaporate more quickly than it can escape.) 4:48-4:55 180°C is 356°F. (The temperature usually creates a lot of damage.) 5:03-5:14 185-230°C is 365-446°F. (The temperature range corresponds with hair straighteners.) 95-200°C is 203-392°F. (The temperature corresponds with curling irons.) I use Fahrenheit, and I thought I might as well post the conversions here. If any of them are inaccurate, let me know
Personally having wet hair gives me the ick it's the second worst feeling in the world, so my priority is to get that dealt with as quickly as possible and damage is just the cost of not needing to crawl out of my skin. I've never met a drier that worked well enough to make it not an ordeal.
I agree, I HATE having wet hair. Also my hair takes forever to dry. If I looked okay bald, I'd have shaved it off long ago. My worst feeling is when my hands are sticky/when it's humid and your skin is sweaty.
My husband and I moved in together after getting married. It wasn’t until then that I learned, post showering, he gets dressed after running a towel haphazardly over 60% of his body. Seeing his wet shirt clinging to his skin makes me feel ill.
as a med student, i think your talent for analogies is incredible and something i oftem try to emulate when speaking to patients! i find myself often trying to come up with these sorts of metaphors because they're incredibly helpful when talking to people who don't have a similar background and sorta laughing about how silly it is helps form a friendlier relationship with them too. only wish i were better/quicker at coming up with them, because they'll often come to me like three days too late hahah
Constructing analogies is just like any other skill! Like how people tell a professional artist “wow you’re so talented” or “I couldn’t make art like that, it’s soo good” even though being artistically inclined doesn’t guarantee an automatically heightened skill in it. That association comes from the way people ignore how much a passion or desire for gaining and improving a skill directly contributes to a betterment in one’s abilities. Additionally, skills must be maintained. I create lots of different types of art, but if I didn’t spend my time learning more or practicing, I’d be absolutely ass at it! I *might* get away with a slightly above level if I never practiced, but is a gamble and even that is still based off of my mental and muscle memory which wouldn’t exist without my passion and dedication to the craft when I was younger. *Most things in this world are skills, skills you can gain, learn more about, and maintain proficiency in.* Although some individuals can have a more intuitive time with some skills, anyone can always learn more about and improve upon any skill* Failure is impermanent and subjective so all that’s needed is a better perspective and the determination to keep going so you can get where you aspire to be :) This reply is… unnecessarily wordy but ¯\_(ツ)_/¯ I’m still gonna post it lmao *that isn’t inherently tied to physical or genetic capabilities as that type of skill is objectively more difficult to maintain.
@@rowannnnnnnnn I def agree with that! It's just that communicating with patients (esp during med school, when you don't have a specialty yet so there's a huge variety in illnesses + you are just less knowledgeable in general), i'll often only speak to a patient once. so there's like a 30min window to explain it hahahah hence why i wish i could come up with them instantly!
@@oliviamayumi I’m glad you know you’ve got all you need to build up the skill :) Like Michelle said after my initial reply to you, you can reflect on your past experiences and practice formulating some potential analogies… even in the shower! I’m fairly sure that each patient you interact with (even if it’s only once) isn’t going to have a completely unique ailment or situation or whatever goes on in med school, right? So if you spend some of your time when you’re at home (like in the shower, doing dishes, etc) to improve on your proficiency in creating analogies, I’m sure that none of that will be in vain. Even if you become discouraged because you find yourself NEVER getting to use a certain analogy (however improbable that is) you will still be gaining the benefit of practice :) I’m gonna liken this to how I often felt very insecure about my own artistic abilities… until I realized that ANY time spent on honing any ability, is ALWAYS beneficial, regardless of the perceived “worth” of the result(s)!!!!! TL;DR: be resilient, the two most hurtful things you can do in terms of your personal improvement is to give up and to never grow. … I’m realizing that all these words definitely seem like common sense and fluff but listen man, they literally work as values to live a happy life by :)
I've thick hair and I hate using a dryer to dry my hair. It just looks bad and dry. I'm probably not that good at it either. For years I have brushed my hair pre shower, and I don't really ruffle my hair while showering, I just let it hang down my back. After I've showered, I squeeze out as much water out of my hair as I can and then use a microfiber towel turban. After that I just let it air dry. Always looks really nice, and tangle free.
I also have thick hair, but air drying makes it frizzier and gives me dandruff. Ever since I started blow-drying my hair and using leave-in conditioner, it has felt less dry, less frizzy and much softer.
12:40 I have been taking plenty of advice from the Blowout Professor who is a hair care & styling TH-camr, hair stylist trainer and salon owner. Regarding drying, he also says that it's better to use a blow dryer instead of letting it air dry but there are a few more steps: 1) using a leave-in conditioner which traps the moisture and keeps the hair healthy 2) using a blowout cream which counters frizz, makes the hair shiny and has heat protection 3) blow drying not only with a blow dryer but also a brush to have a bit of tension in the hair; otherwise it's going in all directions and gets frizzier 4) using a hair oil at the ends to close up hair follicles optional: 5) go into a styling routine with a higher heat protectant and tools; shouldn't be used more than twice per week to keep the hair healthy Personally, I have good experience with these tips but also took to heart that just like skincare, it is individually different and requires therefore different products. My hair is bleached and dry which is why my product choice involves a focus on purple pigments and moisture, whereas other people may need a better colour protection, exfoliator or volumiser.
@it 13:38 LabMuffinBeautyScience it is pretty much in all his videos, his science ain't good, but his advice is. I mostly ignore the specific products and use what I have or something similar and got great results using his methods.
As someone prone to dandruff I now rely on gentle blow drying. Of course, there are lots of internal factors involved like your nutrition and testosterone levels, but the drying hack is worth giving it a shot
I had years of issues with irritated and VERY itchy scalp - tried all kinds of dandruff and also, on the other hand, non-irritating shampoos but nothing worked. Finally (after some big procrastination) went to my dermatologist, and he said that I have to simply wash my hair more frequent (1 time per day or per 1.5 days instead of ever 2-3 days) because my skin might get irritated from the sebum. He also told me to blow-dry it, so there is no moisture sitting on top of my scalp for hours. Prescribed me a light cortisone medication too, but I just had to use it 2-3 times. The more frequent washing and the blow-drying of the scalp at a medium temperature were really the game changers, and I wish I would've known that before and saved my money on all the different shampoos. Thanks for pointing this out in the video, it really does help!
I had a chronical dandruff issue that had been happening for YEARS. Since i remember I've always had dandruff, and also nothing that i did helped, also i have an slight allergy to anti dandruff shampoos. Then at the beginning of this month i did a straight perm, and stopped letting my hair air dry, always blowdrying to avoid sleeping in wet hair..... The dandruff that has been there all my life completely disappeared
I've always avoided sleeping with wet hair cause its annoying... but still have dandruff. I dont blow my hair often, maybe i'll dry it more. Does it really help w dandruff?
@@MinhMinh-eh5woYes, blowing drying did help with my dandruff. I would have never thought it would. I would try it for a month and see will it work for you.😊
@@Sweetlady1916so the wet hair may have created an environment for an overproduction of yeast. I think leaving your hair and/or scalp wet can cause hair and scalp maceration. Glad you’re not having to deal with dandruff anymore.
Hello! I was always against hair dryers or other hair devices and never used them. When I lived in a dry climate, my hair dried quickly and looked good. But when I moved to Asia, where it’s very humid, my old method didn’t work: my hair became very dry, it broke easily, and I didn’t see any growth because it kept breaking. I once saw on the internet that you shouldn't leave your hair wet for too long because it gets damaged faster. I started using a hair dryer, and a simple dryer helped save my hair.
I diffuse my wavy hair on the cool setting because air drying takes hours, and, im not a fan of walking around with a wet head. I havent noticed any damage, and, it only takes an extra 5-10 mins compared to using heat. One bonus ive noticed is the cool air doesnt irritate, and make my scalp itchy, like heat does. Thanks for the info! Im learning a lot. 😊
ok WOW my whole life I've wondered why my hair never holds heat styling for more than an hour or two, and the only way i can get a style to "stick" is by wet-setting. YOU JUST EXPLAINED THAT!! my natural texture is quite fine and mostly straight with the tiniest bit of wave, so it can often look greasy and flat. but whenever i damaged my hair with bleach i found it soo much bouncier and easier to style - you also just explained that!! Man i love science, thanks!
“I will never run out of analogies for this” 😂😂😂 I ADORE YOU! Honestly, thank goodness for you and your channel. You deserve a global award for the service you provide with your content!!! ♥️♥️♥️
Can't ever get enough of your videos. You're just so professional and enthusiastic about what you do, and I love and respect it! One of the best channels out there, in my humble opinion!
That’s just sooooooo idiosyncratic tho - completely depends on hair type (which changes with age), hair damage (which changes with treatment), hair environment (which changes with the seasons or even employment history), and hair style (which changes with the whims of fickle trends). It’s just too many inputs to create a prescription for n-dimension of variables.
I’m 100% sure that the violent detangling process after I have my fine hair bleached is why my hair damage is so much worse than it would be if the stylist was gentle and patient.
Hairdressers also tend to hold the hairdryer up against the brush. They do this to create a similar effect as a straightener or large barrel curling iron would create. At that distance the hairdryer is boiling the water in your hair.
Highly reccomend finding a new stylist and asking the new one to try an acid milk rinse after bleaching! It helps close down the cuticle pH wise plus conditions making the detangling process less damaging!!!
Yes! Have definitely had stylists brush my hair mercilessly after a bleach treatment while was soaking wet. I could literally hear the hair snapping and it HURT. I don't generally have a sensitive head so that is really saying something. I always felt like telling them to go easy on my hair but I don't think they would take kindly to that. Haven't bleached/highlighted my hair in years but have been considering it recently. Your comment brought back all the trauma of rough brushing outs and having them dry the hair right up against the brush so my hair got super hot. It was like they were beating it into submission 😂😢
@@LabMuffinBeautyScience is molecular weight (g/mol or daltons) an important factor to consider when choosing a product that doesn't weigh the hair down?
Omg. I literally just spent two hours conditioning and (doggie) blow drying my Great Pyrenees and was having the hardest time explaining to my actual scientist (blood cancers) boyfriend why it was so important to take the time to do it well during shedding season (aka, me doing it and not him 😂). This is all super important if folks with dogs that are shedding now aren’t trying to bring all the old dog hair back with the dog after the DIY spa day! “Idk, I just know he’s got an insanely fine textured cotton ball undercoat and if you don’t deal with the hydrogen bonds and the Ph, he’ll still have all the undercoat but look like Rob Zombie! Omg, just lemme do it.” I’ll let you explain it with this next time. 🐶
Not to mention that doggos have fur so thick that without blow-drying the moisture can get trapped in the undercoat and cause painful hot spots. Your dog might not be a big fan but I bet he/she is much more comfortable after getting rid of dead undercoat.
Just wanted to tell you that (the famous mail-order company) says your book is arriving today - A whole week early! I'm really looking forward to it! Thanks (from someone with fine, straight hair who's far too environmentally friendly/stingy to do more than clean it, so it always just air dries.
Michelle, THANK YOU for doing hair videos!! I know the science isn’t nearly as robust as for skincare and that’s why it’s harder to learn about, so thank you so much for covering it!! Love your content so much🫶🏻
Girl I LOVE your content but pleaseee explain if Hyaluronic acid used on hair actually makes damaged hair weaker or stronger because I've heard so many opposing views by doctors and just people who tried it out and I wanna know scientifically what it does !! Thank you sm
I have been struggling with bad scalp inflammation and hair loss for the last yearish and it hasn’t gotten much better even using a ketoconazole shampoo every other day. I watched this video about a week ago and your comment about letting hair air dry could cause scalp inflammation because it’s a wet dark environment just made sense! Before I was air drying my hair 95% of the time but I started blow drying my hair on a low setting and I’ve noticed a HUGE difference in my scalp. I will probably never air dry again. Thank you for making this video!
I‘m being serious when I say that your content means so much to me. Hair is such an important part of my self esteem and there are so many voices out there that confuse me. Your videos help me make sense of them and get a better understanding. If you ever doubt yourself/ your content … please do not because they help so many people out tremendously! Thank you
It also depends on where you live. I live in Hong Kong and have very thick hair. It would take hours to air dry in humid days (which are most of the year) so blow dry is the only option! I brought a cheap hair dryer (RMB150 or USD22) from PingDouDou (parent company of Temu), and it turns out to be the best dryer I ever used! It has monstrous air flow, and shows the temperature (in Celsius of course), and could auto switch that blow hot for 5 sec and then cold for 5 sec.... So, now my routine will be wrap my hair in micro-fiber for a few minutes and then blow dry. Start at the max air flow with alternating 70 degree Celsius and cold. When it is almost dry, will turn it down to 45 degree and low air flow till 100% dry.... Perfect!
My scalp does better with blowdrying. So that's what I do. I wash my hair twice a week at night and don't blowdry my ends fully, mostly out of laziness, but it will leave my ends nice and wavy on the next day. If I want I will heatstyle in the morning when everything is fully dried. I heatstyle 2-3 times a month. My hair was always good with this behaviour. Only going blonde was really damaging it. I'm so glad when this hair has grown out no product in the world seems to be able to fix it, just temporarily mask. Great explanation, thanks.
"I am human and get stuff wrong". I love seeing this - thank you for your honesty. That's science - we can change our opinion when we learn more. Thanks for all of the amazing information.
Thanks for this! I had read that study that said that air drying appeared to be more damaging than blow drying and it worried me. I always air dry in order to save time, so your breakdown of the results makes me feel a lot better.
i loved hear you talk about haircare science! could you maybe cover the topic of "normal" and professional shampoos? is there a difference between them?
Such an interesting video and great explanation! I picked up the "hair dryer will automatically destroy your hair" myth from a teen magazine like 20 years ago and of course told my husband this "fact" when he would (very mildly) complain about me sleeping with wet hair during winter. I started finally using a hair dryer because I did agree with him that sleeping with damp hair when it is already super cold made very little sense, but now it has been suggested that the actual mistake with sleeping with damp hair is that your pillow will suck up all of that moisture and cultivate a lovely mold colony inside the the pillow. And then you breath in all the spores they release for 8 hours per day for however long... No wonder my nose got so stuffy whenever I went to sleep. Ew ew ew. Getting a fresh pillow helped immediately. So now I always use hair dryer, so it's nice to hear that it isn't that damaging as I was lead to believe. Super interesting!
Michelle came in clutch!! ☺️ Itme about Midnight for me and I have an appointment tmr 🥹 wasn’t sure wtd. But I think I’ll stay up to shower, blow dry and wait for like an hour before blow drying again
You should make a video on guasha and face rollers idk if that’s apart of chemistry or stuff you know but it would be cool for someone to do a video on if it actually works instead of people doing transformations where it’s obvious they are just changing the way they are holding their face up:)
What isn't mentioned in the video: the air which lets the hair fly around while blowdrying, is damaging aswell. I have white bleached hair, which gets very dry and weak from blow drying. The only blow dryer which makes a little difference is the zuvi halo. But when I air dry, it is so shiny and smooth and moistured. But my hair dries in only 2 hours, its thin.
Huh, thank you for accidentally explaining to me how rag curls work! Also... I have mild dandruff and never considered that air-drying might make it worse! I'm going to start testing a little bit with cool/low air drying. (Also also the knowledge that you don't always need heat protection when blow-drying) (Also x 3 that you can stretch hair when it's wet! I've def noticed but didn't understand why) This whole video is just a wealth of info 💖
So does this mean the blow dryer brushes are the worst for your hair? Mine definitely produces a lot of steam so I can only imagine the water inside the cortex boiling too.
I love how nuanced and detailed your videos are, it really helps to make sound consumer decisions. Every time it's like I didn't know how badly I needed it!
is there any difference in damage patterns for different hair textures or porosity? I have naturally curly hair and I’ve always heard that curly hair is more fragile due to the cuticle being uneven. Or is that another myth?
Hi Michelle! Long time watcher. Could you talk about the difference between “salon” quality or luxury shampoos vs drugstore and if there’s a real difference in quality/performance/etc??? Stylists always push for the high end stuff but I feel like it’s not needed
there’s a world of a difference in my personal opinion and experience. “professional” ones are a lot more concentrated, i don’t need as much and it leaves it CLEAN! Almost like a clarifier but not as drying. Still i like to alternate it with drugstore stuff because you can overdo it and i like having something cheaper and weaker if i need to wash it more often for whatever reason during the week
I've gone through a lot of trial and error in learning how to accentuate my hair's natural waviness, and I'm glad to see that your findings back up what seems to work for me. I've settled on a routine of scrunch drying to set the wave pattern, lightly squeezing in leave-in conditioner by hand, and blow drying with constant motion at a distance of about 15 cm, 2 minutes per side (just enough to get it damp, not fully dry). I've actually grown to prefer my everyday styling to what I get at the salon because they always seem to want to style my hair as if it's straight. I've even asked before if they have a diffuser they could use, but usually they just tell me they don't have the right product for wavy hair and just bust out the concentrator. I've second guessed myself on this one for a long time because I figure, hey, I'm not a cosmetologist, the experts probably know better than me. The older I get though, the more I'm starting to put more trust in my own experience and observation.
It’s all about porosity my older sister has low porosity hair so she HAS to blow dry otherwise her hair will never dry. I on the other hand can’t blow dry because I have high porosity hair so I don’t need a blow dryer because the blow dryer is drying out my already dry hair. We both have 4c hair but our hair reacts differently! That’s why I love having natural hair it’s like a science experiment every time i do it 😂
@@elisglaze6077Take a glass of water & put a strand of product free hair in the water. Floats = low porosity. Sinks slowly or settle in middle= medium/ normal porosity. Sinks to bottom = high porosity.
Is air drying bad for the scalp? I heard it can cause itchiness. I watched the linked video a couple weeks ago but I don’t remember if you talked about that
Thank you for the information. Why is 2A/2B hair brittle with high porosity after washing it with the usual hair shampoo/ conditioner/ water? Even though, no heat is used except minimal cool hair drying.
wait one Second. What about the conditioner method, where you squish in conditioner into your wet hair, to make it even hydrated? is this good or bad for our hair?
I didn't know that slow air drying could aggravate dandruff! Thank you, I will use a blow drier more often now. Although obviously I will use the cold setting. I mean who on earth uses the heated setting if you're not in terrible hurry...
Michelle what about us with curly/kinky hair that use blow dryer to stretch out our hair so that it won’t shrink and get tangled? Will a blow dryer still damage the hair more?
Thank you for the tips! Drying time is the bane of my existence due to my long, thick hair. On a side note, what do you think of cetyl tranexamate mesylate? I know you’re not a huge fan of tranexamic acid, but that derivative cetyl tranexamate mesylate has potential. On PubMed: Results: No questionable adverse reactions were observed. Melanin and erythema indexes improved significantly and continuously from the baseline to the end of the study (-16.9% and -34.3%, respectively). Photographs further support instrumental data. On average, after 2 weeks, the subjects already noticed an improvement in skin tone (79.3%), a reduction in dark spots (78.6%), and an improvement in facial redness (77.1%).
I am so excited about this book! We run two 4000-level research courses (one CHEM coded, one BIOL coded) for our Human Medicine and Biochemical Analysis undergrads. Cosmetic chemistry is a growing field - SO many students are wanting to break into the world of skincare and makeup right now! When I accept students for cosmetic research, we end up jumping between GOB, organic, analytical, and biochem textbooks since there aren't many dedicated books with current knowledge floating around. I am ordering this book now for myself (selfish moment, hah) and I am having our library order it, also. Thank you so much for doing this!
I always use a towel to pull water out after a shower and let it air dry, no brushing or anything. I do have dandruff issues so I think I’m going to try to blow dry my roots and see if that helps.
next topic: disulfide bonds! I'm very much interested about this bond since this is what olapex is trying to repair? I'm surprised to learn there's hydrogen bonds alongside disulfide bonds... huh hair is definitely a complicated mess😅🤣
she actually made a video on this already a while back!!! it should be in one of her playlists about hair, i watched rhe whole playlist a few months ago so i know its there HAHAHHA
Omg science yesssssss! THIS is what I want to know about my hair. It explains SO MUCH about things I've noticed with my hair during the course of life. BRILLIANT.
Yes, any local bookstore of your choice should be able to order it. I often do that, too, rather than ordering online. Usually takes just a day or two.
A leave-on conditioner can limit damage during detangling and air drying. Took me a while before finding the one which does not make my hair greasy. Stop using product with silicones, SLS, parabens and drying alcohols. After my hair has regrown, it is less damaged and not as porous, so it dries even faster. It's been almost ten years since I last had any split ends. I go to a hairdresser about once a year... although now it's been 1,5 years since my last haircut. I am getting fond of the long braids...
I used to blow-dry my hair every other day and straighten after. My hair was so incredibly damaged so I cut 6 inches of damage off and stopped using everything and let it airdry. I did that for 2 years but I developed severe dandruff. I used Nitrogena T-Gel which worked at first but then stopped for some reason so i switched to Nizoral. I also bought a new hairdryer which has a cold setting and now I only ever use it on cold, ensuring I fully dry my scalp (no straightening though, i learned my lesson!). My dandruff I've suffered with for ages has gone and my hair shows no sign of damage. Cold hairdryers are definitely the way forward. Yes it takes longer but so worth it.
OMG amazing video. I always tell my clients "at least" dry your scalp with a blowdryer. Problems coming from an imbalance in the epicutaneous emulsion are worse than those coming from using heat. Loved your video!!
I love my microfibre towels for my hair. Also, I dry my hair with the cool setting in my dryer. Edited to add a tip I wished I had do e myself earlier: if you think you have hair or scalp issues, unfollow all hair influencers on social media and see a professional. I found out I did the opposite of what I should be doing which caused a lot of hair loss and a very sensitive inflamed and super oily scalp.
Since you mentioned bleach and have dyed hair yourself, I'd be really interested on your knowledge about making color last longer versus getting rid of it quickly. There are many products claiming to protect or even refresh color, but personally I assume they don't work at all.
4:14 as someone with very oily scalp and bleaches my hair, i can confirm lmao. extra damaged hair absorbs the oils that normally made my virgin hair a greasy mess
literally watched this while (gently, on low, with my fingers) blow drying my hair! Drying my hair at night rather than sleeping on it wet has been amazing for my dandruff-prone scalp.
I love your videos so much! I’ve had an oily scalp my whole life and lived in a hot, dry climate. Then I moved to a temperate, but humid climate with hard water and my hair FLIPPED. It took a slow descent into unmanageable, broken, insanely itchy and dandruffy, red and literal flakes. I did everything I thought was right. I started using specific products and Sal acid and a satin bonnet and using heat to dry and all of that. I didn’t realize that I was over washing my hair which made it dry and itchy and then trapping the heat from drying (or sometimes wet hair) in a satin bonnet overnight creating more heat and humidity in an already humid climate. Then I would go outside the next day with either still damp hair or hair that felt itchy and dirty again almost into the humidity outdoors where I would sweat and then wash my hair again. It wasn’t until I moved back to my dry climate that I realized how low maintenance my hair could be 😂 now I have no scalp issues, better looking hair, and I use less products and products that work for me. Now, thanks to your video, I know why 😊
This is so helpful! Thank you! I have such a hard time trusting tips and advice when I don't understand how it works, this format is perfect for me. I'll be adding your book to my Christmas book wishlist!
Pro tip for the long haired girlies: throw your hair UP on your pillow, towards your headboard, if your hair is still a little damp when you go to bed. I used to only air dry, but I've started incorporating blow drying if it's too close to bed. Usually I'll do a rough dry once I'm dressed post-shower, let it air dry while I watch tv, and then blow dry one more time right before bed to finish the job. I have the softest hair you'll ever touch 😌
I used to braid it and it would take a couple of days to dry. Now I leave it out until it's dry, detangle and braid it so it doesn't stay wet for so long because of this video. Thanks!
What about using a quality paper towel to squeeze out excess water without rubbing before the microfiber towel?. I’ve been using that and it’s been great. Thank you for the really informative video!
Loved this, I'm an old girl who grew up 14miles/28ishkm from the equator. When young mum would wash our hair in the am so it could dry naturally. There were no shampoo and matching conditioner withe, beer or vinegar was rinsed in my hair 😅. Now I love a turbine twist, sectional dry on lower temperature 🌡️, too hot burns Ur scalp so imagined what it did to my hair. Love the science ❤
Great info Michelle! 😊 I was wondering what your opinion might be on using scalp massagers in the shower. I've heard that they get your scalp more clean and promote hair growth, but then I've also heard they are very damaging to your hair. Any thoughts? Love your content and am wishing you well from the U.S.! ❤
Such a great video, thank you for the effort and clear explanations! I’m confused as to whether heatless curls would be damaging on wet hair? Because it’s sitting in a pulled/curled state? But at the same time it’s air drying… Also people say air drying is damaging for low porosity hair as it tends to be swollen with water for so long, would that be considered physical damage to the hair as well? I know you said water isn’t damaging to hair on its own. 🤔
It could potentially be if you stretch the hair too much, but you can also do it without stretching. I think the swollen = damage thing is based on the CMC bulges in this Lee paper!

used to work with hair stylists for two years and everyone said something different 😢 thank you for sciencing this for us
I've learned sooooo much misinformation from stylists. I think it's because their education heavily relies on how much the stylists who trained them know ..and often it's not much .
@@226iamacake thankfully that's not the case in Germany, here it's a full 3 year trainee programm for hair styling (+basics of make up and nail design) and the people i worked with were all extremely talented and educated in their craft. still no consensus on hair drying 😅
@@PhiloishnessThey may be educated in hair styling and colour processing but not in trichology. It's like that anywhere. They don't really learn about or keep up with the science of hair and scalp care and health. Hairstyling is a vocational/craft kind of educational route not science.
In my experience all my stylists just go by rules of thumb that they have heard somewhere. Even had one say that shampoos with mint reduced hair loss by 30%. I don't even know what to say that. The industry is full of broscience even though they're all educated. In Denmark it's a 1 year education with 3 years of apprenticeship (or something like that), but I suppose they don't have a lot of motivation or opportunity to keep up with the science.
She was incorrect about one thing though. It’s driving me a little nuts lol. She said that bleached hair retains moisturizing ingredients and water easily, it takes longer to dry…nope. It’s actually hair that absorbs moisture quickly, but doesn’t easily retain those nutrients. It’s called high porosity. On the other side of the spectrum, I have low porosity and I have hair that is slow to absorb. It’s harder to get those nutrients in, but once I do it STAYS.
I’m obsessed with haircare, I know she was spreading at least this bit of misinformation.
I explained in a comment on the video (not a reply) why.
i can't believe michelle said she hates hydrogen bonds and that she thinks hydrogen should stop bonding to things and just stay in the sun where it belongs 😮

Wooah, I would have loved to join that class! ❤@@LabMuffinBeautyScience
Too much science for me, can anyone explain what she recommended air drying or blow drying? Wavy to curly hair here
@@LabMuffinBeautyScience we wanna be your students so bad
My entire life I have blow dried my hair (even as a kid). Ppl always found my hair healthy, and at the same time said “blowdry is bad for your hair”. Thanks for explaining it
I'd think genetics or some other variable but I guess it just generally is damaging.
fr people always said my hair looked healthier when i would blow dry it everyday😅
@@haehaev because blow drying it makes it look shinier (I think hydrogen bonds might be at play here too)
@@haehaev blow drying smooths the cuticle, it makes it look and feel healthier but heat damage has little to do with shine, and actually just makes the hair physically weaker
I haven't watched the video right now but air drying my hair always makes my hair to clump up
The earliest I’ve ever been, thank you everyone for witnessing this milestone of my insomnia
🎉🎉 🎊👏👏👏 but seriously, hope you get some rest

No need, I’ll have your new book to keep me company!
I slept at 6:30 am today 😭
Water is a curly girl's main styling product and heat helps set the shape. I always figured blow drying my hair did me more good than air drying because my scalp gets oilier quicker if I air dry.
i heard as a good rule of thumb that if your hair isnt completely dry after 2 hours of air drying you should blow dry. drying your hair is what sets the hydrogen bonds in place, but the heat makes it happen faster because it evaporates water faster and allows the air to carry more moisture away
When mine air dries it clumps together like Velcro and is almost impossible to comb out unless I Comb it while using a blow dryer.
@@dynogamergurl you probably need product then
@@dynogamergurl why comb them out? healthy curls clump. just style it
@@dynogamergurlyou probably just have curly hair and haven't find the right moisturiser/styler yet
By the way, I love that your videos aren't that heavily gender-coded. As a man with awesome long hair, I vibe a lot better with your style of video than many others :)

Can't explain how satisfying it is to hear you cover all factors not just a sweeping "X is better than Z, done." - Also appreciate that that you addressed/re-addressed the article about airdrying being more damaging, thank you for sharing!!
Would you consider doing a video on hair washing technique too? I'm particularly interested in if hair scrubbers are worth it or do more harm than good!
She did, but I don't think she mentioned hair scrubbers. I don't think they're anywhere near necessary, but if you like them, they're probably fine. Just don't scrub in circles, or irritate your scalp.
I had to google what hair scrubber is (know it as scalp massager - loose translation as I never spoke about it in English) ... but: I had some issues with stress damaging my hair and worked with trichologist on that: she recommended using device like that to massage your scalp, but not while washing my hair - just as a massager to use while watching movie or something. I never asked her if I can/should use it during hair wash - it just never occurred to me as a possibility and she never used it on my head while washing my hair.
In general: our scalps have a lot of nerves and massaging it is good for hair grow. Not necessary by any device, you can use your fingers (or your friends or partner as being massaged by someone else is nice in general - at least for me)
I have no research I can quote on this, so take this with a grain of salt.
From my understanding, a scalp brush/massager/shampoo brush (whatever you call it) is not necessary for the average person. Most people don’t need to add more agitation to their scalp as their fingertips are more than enough to massage shampoo in properly.
However, I have seen them be beneficial for at least two groups of people: people who need accessibility devices and people who have super long nails.
Long nails are especially hard to keep damage free when wet (same concept as water making hair more fragile and this more susceptible to damage), so using a device to scrub your scalp, not your fingers to scrub, reduces the likelihood of damaging your nails.
If someone has chronic pain in their hands/fingers or another kind of hand/finger-related disability, it makes it very difficult to properly scrub the scalp. Speaking from experience, it is very easy to get buildup on the scalp that is almost impossible to remove without much more time and energy than is possible to give when already doing something else that is very draining (showering is often very difficult for those of us with disabilities, so anything to make it easier and less exhausting - or even dangerous! - is a very welcome addition.)
So really, I think the average person doesn’t need to at all. If you want to ensure you are cleaning your scalp enough, I would personally just shampoo at least twice *if* once isn’t enough and your scalp still feels a little gross.
My electric scalp massager helps me get rid of build-up from conditioner on my scalp, which helps me reduce dandruff and gives my hair more volume (I have fine hair). I wouldn't use it daily, though, as it can irritate the scalp when used too vigorously. I've also read that scalp massages help increase blood circulation which can help with hair regrowth. So it's like usual: Everything is good in moderation.
Scalp scrubbers are great for people with mobility issues! I don't think they're necessary for most people unless you need or like to use them.
A hair stylist in Sydney who I follow on Instagram recently posted about a "bleach-free" lightener for hair (aka doesn't use hydrogen peroxide but is definitely still a type of bleach) and how it was a "damage-free" way to lighten hair. I was so disappointed to see him post something like that because he's usually super upfront about the damage of colouring hair. There is literally no way to lighten hair that isn't extremely damaging, you simply cannot obliterate the melanin in someone's hair without causing damage and I don't think it helps to mislead people into thinking that you can. It just sets people up for disappointment and confusion in caring for their processed hair.
P.S. I just pre-ordered your book! Can't wait to put it on my "pretty books" bookshelf that I put all of my aesthetically pleasing books on.
It either damages the hair, or it won’t work! Recently I had a hair stylist use a “bleach-free” lightener on me- and she didn’t tell me beforehand. My bleached ends looked so much lighter than the bleach-free roots even though she left it on a long time 😭
I know it's very damaging to hair but I bleached mine years ago and it didn't look damaged. As long as it looked healthy that was good enough for me lol
What about photobleaching? I have naturally blonde hair which gets lighter during the summer. Of course the effect is not very strong nor fast especially as I don't sunbathe. Or is it just a matter of light hair getting damaged by UV, while dark hair doesn't? Just like darker skin doesn't get as easily damaged by the sun as light skin.
@@ninjal7588 for what its worth my dark hair definitely gets bleached by the sun in summer, my hair is very dark brown/black and by the end of summer it's a deep chocolatey brown with a lot of red tones in it! so i think it happens to most hair colours maybe
@@ninjal7588 hair photo bleaching can happen to any hair color. It’s definitely damaging and makes your hair a little dryer, but is nowhere near as bad as bleach. It does depend on your life lifestyle though. I took a summer in Florida one year and my hair was so damaged because I didn’t really take care of it while also constantly being in the sun that it was light brown, even though my hair is naturally dark brown. It felt so crunchy.
4:22-4:37 90°C is 194°F. (The temperature is close to boiling water when the water inside the hair will evaporate more quickly than it can escape.)
4:48-4:55 180°C is 356°F. (The temperature usually creates a lot of damage.)
5:03-5:14 185-230°C is 365-446°F. (The temperature range corresponds with hair straighteners.)
95-200°C is 203-392°F. (The temperature corresponds with curling irons.)
I use Fahrenheit, and I thought I might as well post the conversions here. If any of them are inaccurate, let me know
Personally having wet hair gives me the ick it's the second worst feeling in the world, so my priority is to get that dealt with as quickly as possible and damage is just the cost of not needing to crawl out of my skin. I've never met a drier that worked well enough to make it not an ordeal.
What's the first worst feeling in the world?
@@vyvyhexewood grain/brick are tied
I agree, I HATE having wet hair. Also my hair takes forever to dry. If I looked okay bald, I'd have shaved it off long ago. My worst feeling is when my hands are sticky/when it's humid and your skin is sweaty.
@@laynasnow8550 That's my third worst it's terrible
My husband and I moved in together after getting married. It wasn’t until then that I learned, post showering, he gets dressed after running a towel haphazardly over 60% of his body. Seeing his wet shirt clinging to his skin makes me feel ill.

as a med student, i think your talent for analogies is incredible and something i oftem try to emulate when speaking to patients!
i find myself often trying to come up with these sorts of metaphors because they're incredibly helpful when talking to people who don't have a similar background and sorta laughing about how silly it is helps form a friendlier relationship with them too. only wish i were better/quicker at coming up with them, because they'll often come to me like three days too late hahah
U will 🎉
Constructing analogies is just like any other skill! Like how people tell a professional artist “wow you’re so talented” or “I couldn’t make art like that, it’s soo good” even though being artistically inclined doesn’t guarantee an automatically heightened skill in it. That association comes from the way people ignore how much a passion or desire for gaining and improving a skill directly contributes to a betterment in one’s abilities.
Additionally, skills must be maintained. I create lots of different types of art, but if I didn’t spend my time learning more or practicing, I’d be absolutely ass at it! I *might* get away with a slightly above level if I never practiced, but is a gamble and even that is still based off of my mental and muscle memory which wouldn’t exist without my passion and dedication to the craft when I was younger.
*Most things in this world are skills, skills you can gain, learn more about, and maintain proficiency in.*
Although some individuals can have a more intuitive time with some skills, anyone can always learn more about and improve upon any skill*
Failure is impermanent and subjective so all that’s needed is a better perspective and the determination to keep going so you can get where you aspire to be :)
This reply is… unnecessarily wordy but ¯\_(ツ)_/¯
I’m still gonna post it lmao
*that isn’t inherently tied to physical or genetic capabilities as that type of skill is objectively more difficult to maintain.
Thank you! Yes it is mostly practice, and being a tad obsessive 😅 I come up with great analogies in the shower
@@rowannnnnnnnn I def agree with that! It's just that communicating with patients (esp during med school, when you don't have a specialty yet so there's a huge variety in illnesses + you are just less knowledgeable in general), i'll often only speak to a patient once. so there's like a 30min window to explain it hahahah hence why i wish i could come up with them instantly!
@@oliviamayumi I’m glad you know you’ve got all you need to build up the skill :)
Like Michelle said after my initial reply to you, you can reflect on your past experiences and practice formulating some potential analogies… even in the shower!
I’m fairly sure that each patient you interact with (even if it’s only once) isn’t going to have a completely unique ailment or situation or whatever goes on in med school, right? So if you spend some of your time when you’re at home (like in the shower, doing dishes, etc) to improve on your proficiency in creating analogies, I’m sure that none of that will be in vain.
Even if you become discouraged because you find yourself NEVER getting to use a certain analogy (however improbable that is) you will still be gaining the benefit of practice :)
I’m gonna liken this to how I often felt very insecure about my own artistic abilities… until I realized that ANY time spent on honing any ability, is ALWAYS beneficial, regardless of the perceived “worth” of the result(s)!!!!!
TL;DR: be resilient, the two most hurtful things you can do in terms of your personal improvement is to give up and to never grow.
… I’m realizing that all these words definitely seem like common sense and fluff but listen man, they literally work as values to live a happy life by :)
I've thick hair and I hate using a dryer to dry my hair. It just looks bad and dry. I'm probably not that good at it either. For years I have brushed my hair pre shower, and I don't really ruffle my hair while showering, I just let it hang down my back. After I've showered, I squeeze out as much water out of my hair as I can and then use a microfiber towel turban. After that I just let it air dry. Always looks really nice, and tangle free.
I also have thick hair, but air drying makes it frizzier and gives me dandruff. Ever since I started blow-drying my hair and using leave-in conditioner, it has felt less dry, less frizzy and much softer.
12:40 I have been taking plenty of advice from the Blowout Professor who is a hair care & styling TH-camr, hair stylist trainer and salon owner. Regarding drying, he also says that it's better to use a blow dryer instead of letting it air dry but there are a few more steps:
1) using a leave-in conditioner which traps the moisture and keeps the hair healthy
2) using a blowout cream which counters frizz, makes the hair shiny and has heat protection
3) blow drying not only with a blow dryer but also a brush to have a bit of tension in the hair; otherwise it's going in all directions and gets frizzier
4) using a hair oil at the ends to close up hair follicles
optional: 5) go into a styling routine with a higher heat protectant and tools; shouldn't be used more than twice per week to keep the hair healthy
Personally, I have good experience with these tips but also took to heart that just like skincare, it is individually different and requires therefore different products. My hair is bleached and dry which is why my product choice involves a focus on purple pigments and moisture, whereas other people may need a better colour protection, exfoliator or volumiser.
Those tips sound good, but his explanations for why they work aren't quite right!
@@LabMuffinBeautySciencecan you do a video explaining why you feel what he's saying isn't quite right?
Is there a specific video with all these tips and explanations?
@it 13:38 LabMuffinBeautyScience it is pretty much in all his videos, his science ain't good, but his advice is. I mostly ignore the specific products and use what I have or something similar and got great results using his methods.
I think that's the case with a lot of hair professionals! We need more collaboration between theoretical understanding and practical know-how
As someone prone to dandruff I now rely on gentle blow drying. Of course, there are lots of internal factors involved like your nutrition and testosterone levels, but the drying hack is worth giving it a shot
Yep 👍 if I let mine air dry just once I’m dandruff central
I had years of issues with irritated and VERY itchy scalp - tried all kinds of dandruff and also, on the other hand, non-irritating shampoos but nothing worked. Finally (after some big procrastination) went to my dermatologist, and he said that I have to simply wash my hair more frequent (1 time per day or per 1.5 days instead of ever 2-3 days) because my skin might get irritated from the sebum. He also told me to blow-dry it, so there is no moisture sitting on top of my scalp for hours. Prescribed me a light cortisone medication too, but I just had to use it 2-3 times.
The more frequent washing and the blow-drying of the scalp at a medium temperature were really the game changers, and I wish I would've known that before and saved my money on all the different shampoos.
Thanks for pointing this out in the video, it really does help!
I had a chronical dandruff issue that had been happening for YEARS. Since i remember I've always had dandruff, and also nothing that i did helped, also i have an slight allergy to anti dandruff shampoos. Then at the beginning of this month i did a straight perm, and stopped letting my hair air dry, always blowdrying to avoid sleeping in wet hair..... The dandruff that has been there all my life completely disappeared
I've always avoided sleeping with wet hair cause its annoying... but still have dandruff. I dont blow my hair often, maybe i'll dry it more. Does it really help w dandruff?
@@MinhMinh-eh5woYes, blowing drying did help with my dandruff. I would have never thought it would. I would try it for a month and see will it work for you.😊
@@Sweetlady1916so the wet hair may have created an environment for an overproduction of yeast. I think leaving your hair and/or scalp wet can cause hair and scalp maceration. Glad you’re not having to deal with dandruff anymore.
Yesss. If I skip a blow dry and let mine air dry, I get dandruff immediately.
My hair is wet right now. Need to watch this before proceeding with any further drying action 😂Probably will go with hair dryer no matter what though.
Hello! I was always against hair dryers or other hair devices and never used them. When I lived in a dry climate, my hair dried quickly and looked good. But when I moved to Asia, where it’s very humid, my old method didn’t work: my hair became very dry, it broke easily, and I didn’t see any growth because it kept breaking. I once saw on the internet that you shouldn't leave your hair wet for too long because it gets damaged faster. I started using a hair dryer, and a simple dryer helped save my hair.
I diffuse my wavy hair on the cool setting because air drying takes hours, and, im not a fan of walking around with a wet head. I havent noticed any damage, and, it only takes an extra 5-10 mins compared to using heat. One bonus ive noticed is the cool air doesnt irritate, and make my scalp itchy, like heat does. Thanks for the info! Im learning a lot. 😊
The dog park metaphor cracked me up, thank you for that.
Nice to hear I haven't been imagining my sensitive and easily irritated scalp likes fast drying with low heat instead of leaving it to airdry.
ok WOW my whole life I've wondered why my hair never holds heat styling for more than an hour or two, and the only way i can get a style to "stick" is by wet-setting. YOU JUST EXPLAINED THAT!!
my natural texture is quite fine and mostly straight with the tiniest bit of wave, so it can often look greasy and flat. but whenever i damaged my hair with bleach i found it soo much bouncier and easier to style - you also just explained that!! Man i love science, thanks!

would love to see your review on how often someone needs to shampoo their hair and how/whether to wash the hair when not shampooing
That’s just sooooooo idiosyncratic tho - completely depends on hair type (which changes with age), hair damage (which changes with treatment), hair environment (which changes with the seasons or even employment history), and hair style (which changes with the whims of fickle trends). It’s just too many inputs to create a prescription for n-dimension of variables.
I’m 100% sure that the violent detangling process after I have my fine hair bleached is why my hair damage is so much worse than it would be if the stylist was gentle and patient.
Thats right. This is the most damaging for hair! Hairdressers don't have time to make it gentle
Hairdressers also tend to hold the hairdryer up against the brush. They do this to create a similar effect as a straightener or large barrel curling iron would create. At that distance the hairdryer is boiling the water in your hair.
Highly reccomend finding a new stylist and asking the new one to try an acid milk rinse after bleaching! It helps close down the cuticle pH wise plus conditions making the detangling process less damaging!!!
Yes! Have definitely had stylists brush my hair mercilessly after a bleach treatment while was soaking wet. I could literally hear the hair snapping and it HURT. I don't generally have a sensitive head so that is really saying something. I always felt like telling them to go easy on my hair but I don't think they would take kindly to that. Haven't bleached/highlighted my hair in years but have been considering it recently. Your comment brought back all the trauma of rough brushing outs and having them dry the hair right up against the brush so my hair got super hot. It was like they were beating it into submission 😂😢
I still have a fear of hair stylists because I remember how roughly they brushed out my hair as a kid 💀 fr almost gave me whiplash every time

I’ll let you explain it with this next time. 🐶
Not to mention that doggos have fur so thick that without blow-drying the moisture can get trapped in the undercoat and cause painful hot spots. Your dog might not be a big fan but I bet he/she is much more comfortable after getting rid of dead undercoat.
rob zombie 💀
Wow, the relevance to our fur friends is something I wouldn't have thought of 💜
Just wanted to tell you that (the famous mail-order company) says your book is arriving today - A whole week early! I'm really looking forward to it! Thanks (from someone with fine, straight hair who's far too environmentally friendly/stingy to do more than clean it, so it always just air dries.
Michelle, THANK YOU for doing hair videos!! I know the science isn’t nearly as robust as for skincare and that’s why it’s harder to learn about, so thank you so much for covering it!! Love your content so much🫶🏻
I use a micro fibre hair wrap now, have done for 2 years. I have always air dried my hair because my fine, thin hair dries in 20-30 minutes.
My hair becomes frizzy when blow dried so i prefer air drying
Girl I LOVE your content but pleaseee explain if Hyaluronic acid used on hair actually makes damaged hair weaker or stronger because I've heard so many opposing views by doctors and just people who tried it out and I wanna know scientifically what it does !! Thank you sm
I have been struggling with bad scalp inflammation and hair loss for the last yearish and it hasn’t gotten much better even using a ketoconazole shampoo every other day. I watched this video about a week ago and your comment about letting hair air dry could cause scalp inflammation because it’s a wet dark environment just made sense! Before I was air drying my hair 95% of the time but I started blow drying my hair on a low setting and I’ve noticed a HUGE difference in my scalp. I will probably never air dry again. Thank you for making this video!
I‘m being serious when I say that your content means so much to me. Hair is such an important part of my self esteem and there are so many voices out there that confuse me. Your videos help me make sense of them and get a better understanding. If you ever doubt yourself/ your content … please do not because they help so many people out tremendously! Thank you
It also depends on where you live. I live in Hong Kong and have very thick hair. It would take hours to air dry in humid days (which are most of the year) so blow dry is the only option! I brought a cheap hair dryer (RMB150 or USD22) from PingDouDou (parent company of Temu), and it turns out to be the best dryer I ever used! It has monstrous air flow, and shows the temperature (in Celsius of course), and could auto switch that blow hot for 5 sec and then cold for 5 sec.... So, now my routine will be wrap my hair in micro-fiber for a few minutes and then blow dry. Start at the max air flow with alternating 70 degree Celsius and cold. When it is almost dry, will turn it down to 45 degree and low air flow till 100% dry.... Perfect!
Can you share the name or a link of the hair dryer or a serial number
@@NaturesBreeze-wr6kz It is Konka pro. Not sure about the model no. You might find it in Temu.
@@_anyone5962 okay thank you.
My scalp does better with blowdrying. So that's what I do. I wash my hair twice a week at night and don't blowdry my ends fully, mostly out of laziness, but it will leave my ends nice and wavy on the next day. If I want I will heatstyle in the morning when everything is fully dried. I heatstyle 2-3 times a month. My hair was always good with this behaviour. Only going blonde was really damaging it. I'm so glad when this hair has grown out no product in the world seems to be able to fix it, just temporarily mask. Great explanation, thanks.
"I am human and get stuff wrong". I love seeing this - thank you for your honesty. That's science - we can change our opinion when we learn more. Thanks for all of the amazing information.
i adore the new focus on haircare since there is sooo much misinformation around, it makes my day to see the facts and the science here
I just received your book and I'm reading it cover to cover, MICHELLE IT'S SO GOOD
I love that you changed your mind and owned it. That's what science is supposed to be about!
Thanks for this! I had read that study that said that air drying appeared to be more damaging than blow drying and it worried me. I always air dry in order to save time, so your breakdown of the results makes me feel a lot better.
i loved hear you talk about haircare science! could you maybe cover the topic of "normal" and professional shampoos? is there a difference between them?
I always wondered this, so when I saw this video I clicked immediately😊
SAME. Also, I was about to close my laptop and wash my hair. xD
same. especially as someone with textured hair.
Such an interesting video and great explanation! I picked up the "hair dryer will automatically destroy your hair" myth from a teen magazine like 20 years ago and of course told my husband this "fact" when he would (very mildly) complain about me sleeping with wet hair during winter.
I started finally using a hair dryer because I did agree with him that sleeping with damp hair when it is already super cold made very little sense, but now it has been suggested that the actual mistake with sleeping with damp hair is that your pillow will suck up all of that moisture and cultivate a lovely mold colony inside the the pillow. And then you breath in all the spores they release for 8 hours per day for however long... No wonder my nose got so stuffy whenever I went to sleep. Ew ew ew.
Getting a fresh pillow helped immediately.
So now I always use hair dryer, so it's nice to hear that it isn't that damaging as I was lead to believe. Super interesting!
Michelle came in clutch!! ☺️ Itme about Midnight for me and I have an appointment tmr 🥹 wasn’t sure wtd. But I think I’ll stay up to shower, blow dry and wait for like an hour before blow drying again
You should make a video on guasha and face rollers idk if that’s apart of chemistry or stuff you know but it would be cool for someone to do a video on if it actually works instead of people doing transformations where it’s obvious they are just changing the way they are holding their face up:)
What isn't mentioned in the video: the air which lets the hair fly around while blowdrying, is damaging aswell.
I have white bleached hair, which gets very dry and weak from blow drying. The only blow dryer which makes a little difference is the zuvi halo.
But when I air dry, it is so shiny and smooth and moistured. But my hair dries in only 2 hours, its thin.
Huh, thank you for accidentally explaining to me how rag curls work!
Also... I have mild dandruff and never considered that air-drying might make it worse! I'm going to start testing a little bit with cool/low air drying. (Also also the knowledge that you don't always need heat protection when blow-drying) (Also x 3 that you can stretch hair when it's wet! I've def noticed but didn't understand why)
This whole video is just a wealth of info 💖
So does this mean the blow dryer brushes are the worst for your hair? Mine definitely produces a lot of steam so I can only imagine the water inside the cortex boiling too.
I love how nuanced and detailed your videos are, it really helps to make sound consumer decisions. Every time it's like I didn't know how badly I needed it!
is there any difference in damage patterns for different hair textures or porosity? I have naturally curly hair and I’ve always heard that curly hair is more fragile due to the cuticle being uneven. Or is that another myth?
In depth videos like these are why I look to this channel first for information because she gives more pertinent information.
Hi Michelle! Long time watcher. Could you talk about the difference between “salon” quality or luxury shampoos vs drugstore and if there’s a real difference in quality/performance/etc??? Stylists always push for the high end stuff but I feel like it’s not needed
there’s a world of a difference in my personal opinion and experience. “professional” ones are a lot more concentrated, i don’t need as much and it leaves it CLEAN! Almost like a clarifier but not as drying. Still i like to alternate it with drugstore stuff because you can overdo it and i like having something cheaper and weaker if i need to wash it more often for whatever reason during the week
I've gone through a lot of trial and error in learning how to accentuate my hair's natural waviness, and I'm glad to see that your findings back up what seems to work for me. I've settled on a routine of scrunch drying to set the wave pattern, lightly squeezing in leave-in conditioner by hand, and blow drying with constant motion at a distance of about 15 cm, 2 minutes per side (just enough to get it damp, not fully dry).
I've actually grown to prefer my everyday styling to what I get at the salon because they always seem to want to style my hair as if it's straight. I've even asked before if they have a diffuser they could use, but usually they just tell me they don't have the right product for wavy hair and just bust out the concentrator. I've second guessed myself on this one for a long time because I figure, hey, I'm not a cosmetologist, the experts probably know better than me. The older I get though, the more I'm starting to put more trust in my own experience and observation.
It’s all about porosity my older sister has low porosity hair so she HAS to blow dry otherwise her hair will never dry. I on the other hand can’t blow dry because I have high porosity hair so I don’t need a blow dryer because the blow dryer is drying out my already dry hair.
We both have 4c hair but our hair reacts differently! That’s why I love having natural hair it’s like a science experiment every time i do it
😂
How do you know if you have low or high porosity hair?
@@elisglaze6077google it there’s a water floating test you can do with a strand of hair
@@elisglaze6077Take a glass of water & put a strand of product free hair in the water. Floats = low porosity. Sinks slowly or settle in middle= medium/ normal porosity. Sinks to bottom = high porosity.
Yeah, my hair will air dry in less than 30 minutes. If I use a hairdryer, I use the cool setting and only for a couple minutes.
Same, I have low prosity hair and I always blow dry my hair for 20-30 minutes if not my hair doesn't ever dry.
Is air drying bad for the scalp? I heard it can cause itchiness. I watched the linked video a couple weeks ago but I don’t remember if you talked about that
Thank you for the information. Why is 2A/2B hair brittle with high porosity after washing it with the usual hair shampoo/ conditioner/ water? Even though, no heat is used except minimal cool hair drying.
wait one Second. What about the conditioner method, where you squish in conditioner into your wet hair, to make it even hydrated? is this good or bad for our hair?
I didn't know that slow air drying could aggravate dandruff! Thank you, I will use a blow drier more often now. Although obviously I will use the cold setting. I mean who on earth uses the heated setting if you're not in terrible hurry...
You never running out of analogies is balm to my heart❤
My hair is slowly air drying as we speak! This is very timely!
Michelle what about us with curly/kinky hair that use blow dryer to stretch out our hair so that it won’t shrink and get tangled? Will a blow dryer still damage the hair more?
Thank you for the tips! Drying time is the bane of my existence due to my long, thick hair. On a side note, what do you think of cetyl tranexamate mesylate? I know you’re not a huge fan of tranexamic acid, but that derivative cetyl tranexamate mesylate has potential.
On PubMed: Results: No questionable adverse reactions were observed. Melanin and erythema indexes improved significantly and continuously from the baseline to the end of the study (-16.9% and -34.3%, respectively). Photographs further support instrumental data. On average, after 2 weeks, the subjects already noticed an improvement in skin tone (79.3%), a reduction in dark spots (78.6%), and an improvement in facial redness (77.1%).
I am so excited about this book! We run two 4000-level research courses (one CHEM coded, one BIOL coded) for our Human Medicine and Biochemical Analysis undergrads. Cosmetic chemistry is a growing field - SO many students are wanting to break into the world of skincare and makeup right now! When I accept students for cosmetic research, we end up jumping between GOB, organic, analytical, and biochem textbooks since there aren't many dedicated books with current knowledge floating around. I am ordering this book now for myself (selfish moment, hah) and I am having our library order it, also. Thank you so much for doing this!
I always use a towel to pull water out after a shower and let it air dry, no brushing or anything. I do have dandruff issues so I think I’m going to try to blow dry my roots and see if that helps.
next topic: disulfide bonds! I'm very much interested about this bond since this is what olapex is trying to repair? I'm surprised to learn there's hydrogen bonds alongside disulfide bonds... huh hair is definitely a complicated mess😅🤣
she actually made a video on this already a while back!!! it should be in one of her playlists about hair, i watched rhe whole playlist a few months ago so i know its there HAHAHHA
Omg science yesssssss! THIS is what I want to know about my hair. It explains SO MUCH about things I've noticed with my hair during the course of life. BRILLIANT.
Is there a non-amazon way to get your book? I've been so excited to get it, congrats on this huge milestone!
If you have an indie bookseller in your area, they may carry it. If they don't, they can totally order it for you. (Yay small businesses!)
Yes, any local bookstore of your choice should be able to order it. I often do that, too, rather than ordering online. Usually takes just a day or two.
A leave-on conditioner can limit damage during detangling and air drying. Took me a while before finding the one which does not make my hair greasy. Stop using product with silicones, SLS, parabens and drying alcohols. After my hair has regrown, it is less damaged and not as porous, so it dries even faster. It's been almost ten years since I last had any split ends. I go to a hairdresser about once a year... although now it's been 1,5 years since my last haircut. I am getting fond of the long braids...
I used to blow-dry my hair every other day and straighten after. My hair was so incredibly damaged so I cut 6 inches of damage off and stopped using everything and let it airdry. I did that for 2 years but I developed severe dandruff. I used Nitrogena T-Gel which worked at first but then stopped for some reason so i switched to Nizoral. I also bought a new hairdryer which has a cold setting and now I only ever use it on cold, ensuring I fully dry my scalp (no straightening though, i learned my lesson!). My dandruff I've suffered with for ages has gone and my hair shows no sign of damage. Cold hairdryers are definitely the way forward. Yes it takes longer but so worth it.
OMG amazing video. I always tell my clients "at least" dry your scalp with a blowdryer. Problems coming from an imbalance in the epicutaneous emulsion are worse than those coming from using heat. Loved your video!!
I'd be really interested in your opinions/research on heat protectants and what your recommendations would be 😊
YES! love when you upload! feed me the science! QUESTION: how damaging is Cassia treatments and Henna treatments like you know the "natural" stuff
I love my microfibre towels for my hair. Also, I dry my hair with the cool setting in my dryer. Edited to add a tip I wished I had do e myself earlier: if you think you have hair or scalp issues, unfollow all hair influencers on social media and see a professional. I found out I did the opposite of what I should be doing which caused a lot of hair loss and a very sensitive inflamed and super oily scalp.
Since you mentioned bleach and have dyed hair yourself, I'd be really interested on your knowledge about making color last longer versus getting rid of it quickly. There are many products claiming to protect or even refresh color, but personally I assume they don't work at all.
4:14 as someone with very oily scalp and bleaches my hair, i can confirm lmao. extra damaged hair absorbs the oils that normally made my virgin hair a greasy mess
literally watched this while (gently, on low, with my fingers) blow drying my hair! Drying my hair at night rather than sleeping on it wet has been amazing for my dandruff-prone scalp.
I love your videos so much! I’ve had an oily scalp my whole life and lived in a hot, dry climate. Then I moved to a temperate, but humid climate with hard water and my hair FLIPPED. It took a slow descent into unmanageable, broken, insanely itchy and dandruffy, red and literal flakes. I did everything I thought was right. I started using specific products and Sal acid and a satin bonnet and using heat to dry and all of that. I didn’t realize that I was over washing my hair which made it dry and itchy and then trapping the heat from drying (or sometimes wet hair) in a satin bonnet overnight creating more heat and humidity in an already humid climate. Then I would go outside the next day with either still damp hair or hair that felt itchy and dirty again almost into the humidity outdoors where I would sweat and then wash my hair again.
It wasn’t until I moved back to my dry climate that I realized how low maintenance my hair could be 😂 now I have no scalp issues, better looking hair, and I use less products and products that work for me. Now, thanks to your video, I know why 😊
Omg I thought there's no way you would cover some random product like the Panasonic Nanoe range but you have the same hair dryer as me!
This is so helpful! Thank you! I have such a hard time trusting tips and advice when I don't understand how it works, this format is perfect for me. I'll be adding your book to my Christmas book wishlist!
I'd like to learn of heat protectors for hair actually work and how much. Is there anything that makes some particularly more effective than others?
can you talk about how ionic hairdryers work and whether those are ACTUALLY better than your no-frills regular hair dryer?
Appreciate the Michelle-in-the-wild (or bathroom) B-roll! Great video 💜
I got that hair dryer as soon as I saw your video, and I've been loving it. If I'm staying outside of my place for a few days, I'm taking it with me.
Pro tip for the long haired girlies: throw your hair UP on your pillow, towards your headboard, if your hair is still a little damp when you go to bed.
I used to only air dry, but I've started incorporating blow drying if it's too close to bed. Usually I'll do a rough dry once I'm dressed post-shower, let it air dry while I watch tv, and then blow dry one more time right before bed to finish the job. I have the softest hair you'll ever touch 😌
My Galaxy Brain????!!! I love you, Michelle! Thank you for making science FUN! You are awesome! I'm buying your book. Keep up the AMAZING work!
I used to braid it and it would take a couple of days to dry. Now I leave it out until it's dry, detangle and braid it so it doesn't stay wet for so long because of this video. Thanks!
What about using a quality paper towel to squeeze out excess water without rubbing before the microfiber towel?. I’ve been using that and it’s been great. Thank you for the really informative video!
Loved this, I'm an old girl who grew up 14miles/28ishkm from the equator. When young mum would wash our hair in the am so it could dry naturally. There were no shampoo and matching conditioner withe, beer or vinegar was rinsed in my hair 😅. Now I love a turbine twist, sectional dry on lower temperature 🌡️, too hot burns Ur scalp so imagined what it did to my hair. Love the science ❤
We have the same drying routine!
It's nice to know that something I hit on through years of trial and error actually has some good backing behind it.
Great info Michelle! 😊 I was wondering what your opinion might be on using scalp massagers in the shower. I've heard that they get your scalp more clean and promote hair growth, but then I've also heard they are very damaging to your hair. Any thoughts?
Love your content and am wishing you well from the U.S.! ❤
Such a great video, thank you for the effort and clear explanations! I’m confused as to whether heatless curls would be damaging on wet hair? Because it’s sitting in a pulled/curled state? But at the same time it’s air drying…
Also people say air drying is damaging for low porosity hair as it tends to be swollen with water for so long, would that be considered physical damage to the hair as well? I know you said water isn’t damaging to hair on its own. 🤔
It could potentially be if you stretch the hair too much, but you can also do it without stretching.
I think the swollen = damage thing is based on the CMC bulges in this Lee paper!
Just got the alert that your book is on the way and will be here tomorrow! Excited. Congrats!
