Outstanding! Do you do research on hair relaxed with sodium and calcium hydroxides? What about a unique relaxer like Phytospecific by Phyto with guanidine, (hope I spelled it correctly). Lastly, have you tested gray hair, both natural and relaxed? Do you need any willing volunteers or how do I just send in a sample?
