Psoriasis commonly appears on the knees and elbows, but can also affect the scalp. Scaly white spots, which are actually layers of dead skin with a powdery sheen, are characteristic of the scalp psoriasis condition. In some cases, the white spots can spread to the back of the neck, along the hairline and forehead and behind the ears. According to the National Psoriasis Foundation, topical treatments are often the first line of defense when it comes to getting rid of white spots on the scalp.
Wash your scalp with a shampoo that contains tar or salicylic acid. A tar or salicylic shampoo will help soften the patches of dead skin in mild cases of psoriasis. Massage a quarter-sized amount of shampoo into your scalp for five minutes. Rinse the shampoo and scales away with water.
Apply a topical cream to the white spots. Over-the-counter topical creams that contain anthralin or dovonex contain ingredients that soften the white patches prior to shampooing. Massage a pea-sized amount of topical cream into the affected area using your fingertips. Wait 30 minutes and shampoo the topical cream and the dry skin away.
Ask your physician about prescription medications that may help if your scalp psoriasis is not improving. She may order you to take an oral prescription medication such as cyclosporine, methotrexate or an oral retinoid, to help prevent the multiplication of dead skin cells and treat your condition.
