Abstract
A sprayable hair fixing composition having the following components or reaction products comprising a) from about 0.5 to about 10 wt. % of a high molecule weight copolymer of polyvinylpyrrolidine and vinylacetate, the weight average molecular weight of said polymer being at least about 200,000, b) from about 0.5 to about 8 wt. % of at least about 80 wt. % neutralized copolymer of tertiary butylacrylate, ethyl acrylate and methacrylic acid, and c) a solvent system compatible with the combination of copolymer a and copolymer b, the wt. % of a and b in the range of about 1:4 to about 4:1.
