Causes of Scalp Psoriasis
Scalp psoriasis is an immune system illness. Your immune system overreacts, which results in inflammation and too-rapid cell growth in new skin.
Every 28 to 30 days, new skin cells typically develop. However, every three to four days, fresh skin cells develop and migrate to the skin’s surface in persons with scalp psoriasis. Thick patches of skin are produced when new cells start to replace old ones.
Although the real causes of scalp psoriasis are complicated, it can run in families. Environmental exposures can include skin trauma, sunburn [3], medications, stress, and other inflammatory or autoimmune health conditions. It can also be Poseidon from parents to children.
