Question: how often should you wash your hair if you have scalp psoriasis?
Answer: Medicated shampoos: This is often part of a treatment plan. If you have stubborn scalp psoriasis, your dermatologist may prescribe a shampoo that contains clobetasol propionate. This can be quite effective when used in a shampoo. Studies show that patients can safely use this shampoo every day for up to four weeks.
