Abstract

The hair treatment compositions for imparting volume to hair each contain from 0.1 to 20 percent by weight of one or more terpolymers of vinyl pyrrolidone, vinyl caprolactam and a basic acryl amide monomer and from 0.05 to 10 percent by weight of one or more cation-active hair-care substance. The composition provides a long-lasting volumizing effect to hair treated with it. It is especially effective on damaged hair and provides good combability without loading the hair.
