Abstract

Hair treatment compositions containing a combination of a zwitterionic polymer and a derivative of 2-pyrrolidone. Such preparations improve the condition of the hair, in particular the moisture retention and curl retention capability after cleaning or cosmetic treatment. In addition, the preparations are better tolerated by the skin.
