Over-the-counter shampoos for treating psoriasis include MG217, Denorex, D-Psoria, Neutrogena T/Gel and Zetar, according to Healthline. Consumer shampoos marketed for psoriasis generally contain around 2 percent coal tar.
Doctors often prescribe Dovonex, Tazorec, Vectical and Taclonex for psoriatic scalp conditions. When using topical prescription treatments for psoriasis, removing plaques from the scalp allows the agents to more effectively penetrate the skin, reports Healthline.
Psoriasis is an autoimmune disorder that often causes scaly, red, flaky, dry and irritated plaques to form on the skin and scalp, notes Healthline. Lifestyle changes, including eating a healthy diet and getting regular exercise, also improve the condition.
