Abstract:
A method of nourishing hair shafts, each hair shaft comprising a cuticle layer and a cortex enclosed in the cuticle layer, said method comprising the steps of:hydrating hair shafts to open flaps of the cuticle layer; applying to the hair shafts amino acids and/or peptides for hair nourishment having a molecular size smaller than the gaps between the flaps, wherein said amino acids and/or peptides are present in the openings between the flaps; and then compressing the hair shafts under heat by sandwiching the hair shafts between plates heated to above a boiling point to generate steam between the plates and simultaneously to press the flaps of the cuticle layer, whereby the amino acids and/or peptides penetrate through the cuticle layer and are confined inside the hair shafts.
