Abstract

A hair treatment composition comprising (A) a keratin-reducing substance; and (B) a nonionic amphiphatic compound which contains at least one long-chain branched alkyl or alkenyl group per molecule, and which has an HLB of 2-12, the compound itself or a mixture of the compound and water maintaining a liquid crystal structure at a temperature ranging from 0.degree.-50.degree. C. The composition possesses excellent moisturizability, smoothness and softness, exhibits a remarkably high conditioning effect which is sustainable, and exhibits the effects of reducing damage to the hair and preventing the occurrence of split hairs, and imparting gloss to the hair.
