Abstract
Abstract A clear shampoo composition for the treatment of ''''living'''' hair and the human scalp which includes an astringent metal salt that causes a reduction in the activity of the sweat glands of the scalp, thereby aiding in maintaining cleanliness of the hair and scalp and helping to combat conditions that favor development of acne. A specific formulation includes, as cleansing agent, a higher alkyl di-lower alkyl amine oxide or higher acylamido lower alkyl di-lower alkyl amine oxide or mixture thereof and an Nhigher alkyl, N,N-di-lower alkyl aminopropane sulfonate or Nhigher acylamido-lower alkyl, N,N,-di-lower alkyl aminopropane sulfonate, or mixture thereof.
