Low VOC hair spray resin compositions containing homogeneous terpolymers of vinyl pyrrolidone, vinyl caprolactam and 3-(N-dimethylaminopropyl) methacrylamide are described. The hair spray compositions are made using a solution of the terpolymer which is clear and low in viscosity, and which provides a spray of relative small particle size. The hair spray compositions exhibit an effective high humidity curl retention property.
