The invention provides compositions for providing body, fullness and texture to otherwise fine or very fine keratinous fibers, particularly human hair. The compositions of the present invention have a high pH, e.g., about 8 to about 10 when the compositions contain cationic polymer, and a pH of about 8 to about 14, preferably about 8.5 to about 13, and more preferably, about 8.5 to about 10 when the compositions contain no cationic polymer. The compositions include one or more nonionic and/or cationic polymers, which, in combination with the high pH of the composition, lift the hair cuticle and allow the deposition of polymer, thus resulting in increased fullness and texture to the hair. The compositions of the present invention may be in the form of known hair care products such as, for example, shampoos, rinses and conditioners. In addition, the compositions can be formulated, for example, as lotions or creams, and the like, for consumer use. The hair care compositions of the present invention provide beneficial and long-lasting effects of body and fullness within a minute or less after application to the hair. |
