At a beuty salon one might request a “permanent” to alter the shape of ones hair which is chiefly composed of fibrous proteins known as keratins. to increase the waves or curls in one’s hair, the beatician treats your hair with a reducing agent ( eg ammonium thioglycolate) uses rollers to reshap the hair, and then treats the hair with an oxidizing agent ( eg dilute hydrogen peroxide) what do you suppose is the chemical basis of a ” permanent”?
