Waterless shampoo is easy to use and convenient for times when bathing with water is difficult. Simply apply, massage, and towel dry. Requires no water. Mild formula works quickly, and since it contains no alcohol and is pH balanced, it's gentle on the hair and scalp. Great to use on children and geriatrics, for convalescent care or for the physically challenged, and is super convenient when traveling in environments where water is unavailable, such as camping and hiking.
