9Phototherapy
Another effective treatment for scalp psoriasis is phototherapy. In this procedure, a special device is used to release UV light directly to the scalp. This device would be like a comb or a laser. The therapist may separate your hair with a blow dryer to allow the light to reach the skin. You may visit a clinical center or a hospital for this treatment. It may be done 3 times per week in 6 to 8 weeks or until the symptoms have improved. Phototherapy may cause pain, which typically subsides after 1 week. [9]
