Disclosed are compositions for washing, cleansing, and/or conditioning keratinous substrates, comprising, in a physiologically acceptable medium: a) at least one anionic film-forming polymer chosen from polymers and copolymers of acrylic acid, methacrylic acid, and/or mixtures thereof； b) at least one ampholytic polymer having at least one acrylic acid moiety and a cationic charge density ranging from greater than 1 meq/g up to about 3.5 meq/g； and c) at least one surfactant base； wherein the at least one anionic film-forming polymer and the at least one ampholytic polymer form an association； and wherein the pH of the composition ranges from about 5 to about 7. Also disclosed are processes for washing, cleansing, and/or conditioning keratin substrates using the composition, and processes for imparting volume to the hair.
