シャンプー・トリートメントによる毛髪の修復機構

抄録

Because of shampooing, drying, brushing etc., hair twists, breaks or acquires split ends; furthermore the cuticle may come off. We tried developing a shampoo agent and conductive treatment agent which repairs hair damaged by washing, drying, brushing, coloring, or perming. The effect of both agents on repair of damaged hair was examined by transmission electron microscopy and electrical conductivity. We compared previous data of optical microscopy with transmission electron microscopy images. As a result, it is clear that a scale-forming material, like a cuticle, is deposited in the keratinization region, and the frizzled hair became straight, because of using shampoo agent and conductive treatment agent containing hematin. These facts suggest that components of shampoo, treatment and/or hair cortex are preferentially adsorbed to the asperities of fragments which are cut off from the cuticle and then these components produce the scale-forming material, like a cuticle, due to epitaxial growth.
