Abstract
Abstract Hair fixative preparations suitable for application to hair without subsequent rinsing are disclosed. The preparations are clear, aqueous mixtures of polydiorganosiloxane and a cationic, organic polymer. The preparations are used for setting hair and may be formulated into lotion and gel type products with superior aesthetics because of the clarity of the mixtures. The preparations are effective in providing flexible, long-lasting hold for hair styles.
