This invention relates to a 0.5 to 7 wt.% solids hair fixative composition having superior moisture resistant hold and minimal tack duration which provides a stiff film on artificial or human hair and superior hair combability, which composition essentially contains a resin mixture of (a) a terpolymer derived from about 17 to about 30 wt.% N-vinyl pyrrolidone, from about 60 to about 80 wt.% N-vinyl caprolactam and from about 3 to about 6 wt.% di-C1-C4 alkyl amino-C1-C4alkyl-acrylate or methacrylate having a number average molecular weight of between about 20,000 and about 200,000 and (b) an N-vinyl pyrrolidone/vinyl acetate copolymer having a number average molecular weight of between about 10,000 and about 100,000; combined in a weight ratio of 1.4-6:1 (a) to (b). In the present composition, the vinyl acetate moiety of N-vinyl pyrrolidone/vinyl acetate copolymer interacts with resin (a) to reinforce stiffness and holding properties under conditions of extremely high humidity and materially lowers the duration of tackiness during drying.
