Hair cleansing composition

Abstract

Provided is a hair cleansing composition containing (A) an amphipathic amide lipid, (B) an anionic surfactant and (C) a silicone. The hair cleansing composition of the present invention has advantages such as protecting hair from physical or chemical stimulation and preventing split ends or hair breakage~without impairing its cleansing ability and,feeling upon use, and moreover, gives to hair after shampooing a pleasant feeling to the touch and moisture retention properties such as natural smoothness, moist feeling, and suppleness which healthy hair inherently possesses, and has excellent stability.
