The compositions also contain one or a mixture of therapeutic agents such as climbazole or a mixture of climbazole and one or more co-therapeutics such as salicylic acid. The combination of mild surfactant system and therapeutic agent serve to prevent or treat mild skin disorders such as scalp itch and scalp irritation when applied to the scalp as a shampoo. Shampoo compositions also preferably contain one or more conditioning agents and suitable suspending agents. The invention also provides a method for treating dry skin comprising applying certain of the therapeutic agents to dry skin to promote the natural secretion of sebum.
