Understanding Scalp Psoriasis: Causes, Symptoms, and Treatment Options

Scalp psoriasis is a common inflammatory skin condition characterized by red, scaly patches that often appear on the forehead, behind the ears, the sides of the nose, or the back of the neck. Sometimes, the condition is limited solely to the scalp without affecting other skin areas.

The severity of scalp psoriasis varies from mild to severe and can differ among individuals. It is not contagious and often results from immune system issues, leading to rapid skin cell growth and plaque formation.

Genetics also play a role, as those with a family history have increased risk. The most common form is chronic plaque psoriasis, which can spread to elbows, knees, the scalp, and the back. Other affected areas include legs or regions where skin contacts fingers. About half of psoriasis cases are of this type.

Symptoms range from mild scaling to severe dryness, itching, soreness, hair loss, bumpy patches, and dandruff flakes. Importantly, most evidence suggests that scalp psoriasis does not cause hair loss directly.

Excessive scratching from irritation can cause hair thinning. Stress may also contribute to temporary hair loss. If you notice these symptoms, consulting a dermatologist is advised. A skin biopsy can help clarify the diagnosis.

Standard treatments involve topical corticosteroids, along with other medications such as:

Vitamin D analogs

Coal tar shampoos

Retinoids

Anthralin

Because these treatments can be challenging to use alone, doctors may prescribe lotions, foams, solutions, or sprays for targeted application.

Currently, no permanent cure exists for scalp psoriasis or dry scalp conditions. While managing symptoms is feasible, ongoing care helps control flare-ups and prevent progression. Consistent treatment often reduces recurrence and prolongs remission.
