    Abstract: A total head care package of a solid stick-like scalp cleanser and a cleaning and conditioning hair shampoo is provided along with a method of cleansing the scalp and cleaning and conditioning the hair.The solid scalp cleanser is a substantially anhydrous formulation which includes soap, amphoteric detergent and antimicrobial agent in a wax-like base.The hair shampoo both cleans and conditions the hair and includes a cationic salt of a primary aliphatic amine with amphoteric detergents. The hair shampoo is typically in the form of a gel. The cationic salt increases strength and stretchability of the hair shafts and reduces static charge buildup.The solid scalp cleanser which may be molded into a lipstick configuration is first applied to the scalp and, before the scalp cleanser is removed the hair shampoo is applied. Both products are then removed by rinsing.
