Abstract
Abstract Disclosed herein is a hair treatment which comprises the following two ingredients (A) and (B): (A) polyphenol compound . . . 0.001-5.0 wt % (B) chelating agent . . . 0.01-5.0 wt %. Also disclosed a hair treatment which comprises, in addition to the ingredients (A) and (B), the third ingredient (C): (C) At least one decomposition derivative of keratin material selected from the group consisting of (1) hydrolysates of keratin material, (2) alkali salts of decomposition products obtained by oxidation of keratin material, and (3) alkali salts of derivatives at the thiol groups of decomposition products obtained by reduction of keratin material . . . 0.05-10.0 wt %. The hair treatment according to this invention can prevent proteins from eluting from hair and restore appropriate degrees of resiliency and flexibility of the hair which have once been lost by treatments for beauty care.
