ABSTRACT OF THE INVENTION This invention relates to the use of low molecular weight polymers in a high solids hair spray composition containing levels of volatile organic compounds 80% or lower by weight. The hair fixative polymers suitable for use in these hair sprays are based on acrylic and vinyl-ester resins that are water soluble with neutralization. The polymers have intrinsic viscosities ranging from 0.100 to 0.300 and are present in amounts ranging from 7 weight percent to 20 weight percent, based on the total weight of the hair spray composition. The use of a lower molecular weight polymer reduces the viscosity, enhances the spray characteristics, and promotes the hydrolytic stability of the system. The high solids content compensates for any lower fixative properties generally associated with lower molecular weight hair care polymers.
