Scalp Psoriasis

Psoriasis is a chronic inflammatory disease that causes red, scaly patches on the skin. It is estimated to affect approximately 2.2% of the adult population. This skin disease can be caused by environmental and genetic factors. Some affected individuals may be genetically predisposed to psoriasis, as certain genes appear to be involved with the control of the immune system.

This can lead to an overactive immune response, triggering inflammation characterized as psoriasis.

Scalp psoriasis is a common skin disorder that makes raised, reddish, often scaly patches. It can pop up as a single patch or several, and can even affect your entire scalp. It can also spread to your forehead, the back of your neck, or behind your ears.

It is generally accepted that scalp psoriasis, like all psoriasis, is related to genetic defects that affect certain parts of the immune system. There are undoubtedly environmental factors that trigger its initial development in genetically predisposed individuals. The belief that “emotional stress” plays a causal role or at least exacerbates psoriasis has been difficult to prove.

Scalp psoriasis itself doesn’t cause hair loss, but scratching a lot or very hard, picking at the scaly spots, harsh treatments, and the stress that goes along with the condition can lead to temporary hair loss. Fortunately, your hair usually grows back after your skin clears.

At least half of people with psoriasis have it on their scalp. The skin cells on your scalp grow too quickly and make powdery scales called plaques. The areas around them can be red and itchy.

If you have mild scaling, it may get better on its own. Sometimes, though, you’ll need treatment. It can take a couple of months or longer to get more severe  dandruff under control. Once you do, you may be able to keep it from flaring with special shampoos or moisturizers.

Treatments are often combined and rotated because a person’s psoriasis may become less responsive to medications after repeated use. Systemic treatments are not commonly used just for scalp psoriasis but may be used if psoriasis is present elsewhere on the body and/or the psoriasis is moderate to severe.
