Scalp Psoriasis

Scalp psoriasis occurs in at least half of all people with psoriasis. It can range from very mild with fine scaling to very severe with thick, crusted plaques. Scalp psoriasis may appear as lesions that extend from the hairline onto the forehead and the nape of the neck. It is common for the psoriasis to appear behind the ears. Scalp psoriasis usually accompanies plaques in other areas of the body. Scalp psoriasis scales appear powdery with a silvery sheen. Possible causes of scalp psoriasis include: scalp treatments and severe psoriasis can both cause temporary hair loss; itching, picking and scratching lesions can worsen the psoriasis by causing a Koebner phenomenon (psoriasis appearing on the site of skin injuries).
