Unraveling the Mystery of Scalp Psoriasis: What Experts Want You to Know
Scalp psoriasis is a common skin disorder that causes raised, reddish, often scaly patches. It can occur as part of general psoriasis or be limited to the scalp. Understanding this condition can significantly improve the quality of life for those affected.
Understanding Scalp Psoriasis
Scalp psoriasis is a chronic autoimmune condition that accelerates the life cycle of skin cells, causing them to build up rapidly on the surface of the skin. These excess skin cells form scales and red patches that are often itchy and sometimes painful. Scalp psoriasis can range from mild, with slight fine scaling, to severe, with thick, crusted plaques covering the entire scalp. The condition can also extend beyond the scalp, affecting the forehead, the back of the neck, or the skin around the ears.
What Does Psoriasis Look Like?
Psoriasis patches (plaques) are distinct and noticeable because they are thicker and more inflamed than eczema. They are often covered with a silvery, scaly layer. On the scalp, these plaques can extend beyond the hairline.

Scalp psoriasis symptoms can range from mild scaling to thick, crusted plaques covering the entire scalp. Here’s a table detailing ten common signs and symptoms:
