Answer
Scalp psoriasis and seborrheic dermatitis of the scalp can be difficult to differentiate. Both are common conditions that affect the scalp. In addition, they share similar symptoms, such as itchy, red, scaly skin. Fortunately, they also share some similar treatments, such as medicated shampoos. However, scalp psoriasis tends to be more resistant than does seborrheic dermatitis to these treatments.
Most often, the scales of psoriasis are thicker and somewhat drier in appearance than are the scales of seborrheic dermatitis. In addition, psoriasis usually affects more than one area of the body. So if you have scalp psoriasis, you may also have mild psoriasis on your elbows, knees, buttocks or fingers.
There is no single test to confirm a diagnosis of psoriasis or seborrheic dermatitis. A diagnosis is usually made with a visual examination of the affected skin. In rare cases, a skin biopsy may be needed to differentiate between the two disorders.
