Abstract
Abstract A hair setting composition comprising: (a) a film-forming carboxylic resin, (b) a polyvalent metal compound capable of forming metal salt linkages with the carboxylic moiety of the resin, and (c) a volatile alkaline compound which forms with the metal compound a complex which is initially soluble in the hair setting composition when the pH of the composition is 8.5-10.5. The compositions are formulated as lotions or aerosols and hair styling with the compositions is facilitated by application with hand-held, portable, hot air generating devices.
