Description

  The present invention relates to a hair treatment composition. More specifically, the present invention relates to a hair treatment composition that can equalize the degree of internal damage in the hair and impart a uniform feel to the hair when used on hair having different internal damage.

Hair is easily damaged by chemical treatment with an oxidative hair dye, a permanent agent, etc., heat treatment with a dryer or the like. For this reason, the development of hair treatment agents aimed at improving the feel of hair (for example, the firmness and stiffness of hair) has been studied.
Specifically, for example, there has been proposed a hair cosmetic that can give a firmness and firmness to the hair and improve the feel of the hair by combining keratin hydrolyzed polypeptide, L-proline, and amino acid (patent) Reference 1).
Moreover, hair cosmetics that can prevent hair damage and provide a repair effect by combining a chloromethacrylic acid choline ester copolymer, an amino acid, and a cationized keratose have been proposed (see Patent Document 2).
Furthermore, an improving agent that can improve the firmness and stiffness of hair by using a compound such as cystine as an active ingredient and promoting the expression of hair-related genes has been proposed (see Patent Document 3).
