Abstract
Combinations of polymer compounds and hair treatment compositions containing them are described, which have improved film-forming properties and improved hair-fixing properties, particularly increased elasticity of the polymer film or the treated hair. The polymer compound combinations include at least one terpolymer of vinyl pyrrolidone, vinyl caprolactam and basic acryl amide monomer and at least one anionic or anionizable polymer with anionic or anionizable groups.
