Scalp psoriasis is a chronic skin condition that causes red, scaly patches on the scalp. It occurs when the immune system mistakenly accelerates skin cell production, leading to a buildup of cells that form thick, silvery scales. This condition can be itchy and uncomfortable, and it may extend beyond the hairline to the forehead, neck, and ears. While scalp psoriasis can affect anyone, it often appears in individuals with a family history of the condition. Treatment options include topical medications, phototherapy, and systemic treatments, which aim to reduce inflammation and slow down skin cell growth.
