What is Scalp Psoriasis?

The scalp is one of the most common areas that are affected by psoriasis. Worldwide, approximately 2-3% of the population are affected by psoriasis. Up to 50% of psoriasis patients have scalp psoriasis, either alone or with other areas of involvement. Like psoriasis that affects other areas of the body, severity varies widely among patients.

In scalp psoriasis, the body over-produces skin cells, which pile up at the scalp, creating lesions which can resemble dandruff flakes in the milder cases. In moderate to severe cases, the plaques are inflamed and the skin becomes thickened, which often traps clumps of hair. The plaques can extend beyond the hairline, affecting the forehead area.

• Stubborn cases of scalp psoriasis can be difficult to treat with traditional creams, especially for those with longer hair.
• Dry patches, called lesions will often resemble psoriasis on other areas of the body.
• Scalp psoriasis can be itchy, inflamed, or otherwise irritating.
• Severity of itch or soreness can vary from severe to non-existent.
• Mild cases of scalp psoriasis can be difficult to differentiate from seborrheic dermatitis, or simple dandruff.
• Similar to other forms of psoriasis, it cannot be cured, but it can be controlled through a variety of methods.
• Cutting the hair short can benefit treatment as it will allow for better sunlight exposure, which helps, and it makes it easier to apply topical medication to the scalp.
• In severe cases, hair loss can occur. However, this effect is temporary, and the hair will grow back once the psoriasis flare is under control.
