Abstract: Automatic hair shampoo machines were the basis of my U.S. Pat. No. 3,521,647. It overcame the problems associated with prior automatic shampoo machines. One of the imperfections of my earlier hair shampooing apparatus was its washing action. Another one was that during the time the apparatus of U.S. Pat. No. 3,521,647 was in service, it became apparent that the use of liquid tanks or reservoirs imposed limitations on its use. Still another area subject to improvement was a lack of a hair drying apparatus. By improvements herein a hair shampoo machine is provided which can be used unattended. It has an improved washing action, uses no tanks, and incorporates a hair drying apparatus. The washing action has been improved by, among other things, manifolds mounted at definite angles to complement each other. The solution tanks have been eliminated and replaced by a system which injects quantities of hair treating solutions. The hair drying apparatus includes outlets in the bowl or cover of the machine.
