Abstract
Abstract Hair care compositions are disclosed containing a combination of carboxyfunctional polydimethylsiloxane and a cationic, organic polymer. The compositions can be used as hair fixatives and as such may be formulated into aerosol, pump spray, lotion, cream or mousse type hair care products. The compositions are especially effective in providing flexible, long-lasting hold to hair styles.
