Abstract: Automatic hair and scalp treatment machines are known which include a bowl, and a closure therefor, adapted to enclose the head with the face outside the closure. Also included are spray manifolds on an oscillating arcuate header, and driving means imparting partial rotation to the arcuate header. It has been found that dermatoses characterized by the formation of skin cells too rapidly to be eliminated, such as psoriasis, can be treated with this apparatus. Without the machine, removal of the dead cells or plaques is both time consuming and messy. In this treatment it is desirable to begin with low pressure sprays, and increase the pressure to the maximum which the patient can tolerate. One form of apparatus which could be used for this purpose is the machine disclosed in U.S. Pat. No. 4,834,121. In that prior art device the pressure regulator was a conventional regulator ahead of the header. By this invention an adjustable pressure means is provided.
