Psoriasis can cause thick flaky patches on the head, the elbows, and the knees.
Sometimes, it can affect the entire body. Because psoriasis is difficult to treat, people may need to use different medicines. Some people use shampoos with zinc for the head, and creams with steroids for the body. In some cases, UV light treatment can help. Treatment with the anti-HIV drug AZT can also help to reduce psoriasis.
