Conditioning Composition for Keratin Fibres
The present invention relates to a conditioning composition for keratin fibres especially human hair comprising particular cationic polymers and a cationic silicone compound. The present inventor has surprisingly found out that an aqueous hair conditioning composition comprising at least two cationic polymers, one being a cationic polymer with multiple cationic sites and with multiple ester groups in its molecule and the other cationic polymer is being a cellulose derivative, and a cationic or cationizable silicone improves hair combability, smoothness shine, elasticity and more interestingly hair treated with such a composition has volume and body and excellently manageable.
