Gennifer Miller of the hair blog Healthy Textures interviewed Dr. Ali N. Syed from Avlon Organics (makers of Keracare products). In this interview, Dr. Syed does a fantastic job of explaining how relaxers work in lamens terms. He does a fantastic job explaining the difference between no-lye and lye relaxers and what to look out for when applying a no-lye relaxer. ALL Self-Relaxers should listen to this video, but everyone, relaxed or natural, should listen to this video to truly be informed about relaxers.
Dr. Ali Syed, also has a website outlining the effects of many other products like BKT, Keracare products, and more. Be sure to check it out as well.
