Scalp Psoriasis. What Is It?
Scalp Psoriasis is a common skin disorder that produces raised, reddish, and often scaly patches. It can appear as one or multiple patches on the scalp, affect the entire scalp, and spread beyond the scalp to the forehead, back of the neck, or behind the ears. The back of the head is a common site for psoriasis, but multiple areas of the scalp, or the whole scalp may be affected.
Scalp psoriasis is characterised by thick silvery-white scale over well-defined red thickened skin. In some cases, psoriasis may extend slightly beyond the hairline (facial psoriasis).
Scalp psoriasis, even though often adequately camouflaged by the hair, is often a source of social embarrassment due to flaking of the scale and severe ‘dandruff’. Scalp psoriasis may not cause any symptoms at all or may be extremely itchy. It tends to be a chronic problem, lasting many years, although it often fluctuates in severity and extent.
In very severe cases there may be some temporary mild localised hair loss, but scalp psoriasis does not cause permanent balding.
