Psoriasis of the Scalp

Psoriasis of the scalp is a chronic skin disease that usually affects the scalp more than other parts of the body. It ranges in intensity from mild to severe. With psoriasis of the scalp, parts of the skin grow at a much faster rate than usual and develop red, scaly patches. Psoriasis is a concern for many patients mainly because it is uncomfortable, very itchy and unpleasant in appearance. Although many skin diseases are contagious, psoriasis of the scalp is not. It is not considered dangerous, however, it can be hard to treat and quite persistent.

Causes for Psoriasis of the Scalp

It is difficult to pinpoint the exact cause of psoriasis of the scalp, because it may develop either in isolation or with any other types of psoriasis. Contributing factors include genetic factors, the immune system negatively affecting the skin and environmental factors like sun exposure, smoking and drinking. It is believed that regular blow-drying and use of other styling products can exasperate the skin condition because the scalp can become very dry and irritated.

Symptoms for Psoriasis of the Scalp

Psoriasis of the scalp usually develops at the back of the head but less noticeable areas of the scalp or the entire scalp may be affected. The condition is typified by thick silvery white scale on blotches of very red skin. It may travel a bit over the hairline. The condition, even through usually cover by the hair, can cause one to be extremely self-conscious because of scaling and flaking. Some people think it is some type of “severe” dandruff, but find that dandruff shampoos aren’t very effective. If you have the condition, it may or may not cause symptoms. Since it is a chronic condition, symptoms like itchiness may come and go, and may last a lifetime. In extremely severe cases the condition may cause mild localized hair loss that is temporary—psoriasis of the scalp is not known to cause permanent balding.

Diagnosis of Psoriasis of the Scalp

The diagnosis of psoriasis of the scalp is usually not a one-step process since a physician will have to try and differentiate psoriasis of the scalp from other scalp problems. For instance, there are many causes of scalp flaking, and not just psoriasis. A physical exam is often used to make the differentiation. Your doctor will search for nail pits and psoriasis in other parts of your body. A skin biopsy is often performed to make a clear confirmation.

Treatment of Psoriasis of the Scalp

The treatments utilized to treat psoriasis of the scalp have identical ingredients as with those utilized to treat body psoriasis. However, the vehicles are different. Heavy creams and ointments are often inconvenient and not ideal for treating the scalp. It is often advised to apply medication in the form of liquids, shampoos, foams and oils to treat psoriasis of the scalp. Drugs may also be used, such as coal tar, keratolytics, Dovonex, corticosteroids and anthralin. Furthermore, biologics may be administered into the body rather than topically to treat the scalp condition. Other treatments include light therapy specifically designed to treat the scalp, however, light therapy does carry a risk that may increase your chances of developing skin cancer.

There is no exact preventative measure that can be taken for psoriasis of the scalp. However, it is often advised that patients make it a habit to comb and brush to get rid of scaling. Good hygiene practices are advised alongside maintenance treatments.
