What Is Scalp Psoriasis?
1. Scalp Psoriasis
Scalp psoriasis is just psoriasis that affects the scalp. It can cause the scalp to appear scaly, reddish, and have raised patches. It can only be a single patch or affect the entire scalp. In some cases, it may affect the back of the neck, behind the ears, and forehead. Just like any other case of psoriasis, it is noncontagious and the cause of it is unclear. The risk of scalp psoriasis increases in those with positive family history. It is estimated that about 50% of 7.5 million Americans with psoriasis have it on their scalp. While some cases are mild and can be unnoticeable, there are also those with severe scalp psoriasis resulting in thick crusted sores. It can also cause itching, leading to sleep deprivation, hair loss, and skin infections.
