<p>Damaged or imperfect hair shafts are treated by: (a) hydrating hair shafts to open flaps of the cuticles layer, (b) applying to the hair shafts amino acids or peptides effective to nourish hair, and (c) compressing the hair shafts under heat by sandwiching the hair shafts between heated plates to cause the amino acids or peptides to penetrate through the cuticle layer and close the openings between the flaps. The penetrated amino acids or peptides nourish the cortex. The hair shafts may be subjected to hair styling treatment.</p> |
