Abstract
Abstract Hair care compositions which give both improved style and hair conditioning properties are disclosed. These compositions comprise from about 0.05% to about 10.0% of a nonrigid silicone gum, said gum having dispersed therein from about 0.01% to about 8.0% of unsolubilized particulate matter which is preferably an octylacrylamide/acrylate/butylaminoethyl methacrylate copolymer.
