Is it Scalp Psoriasis or Seborrheic Dermatitis?
Two conditions can cause flaky, itchy scalp: psoriasis and seborrheic dermatitis. Psoriasis is a chronic autoimmune disease that causes an immune response that results in a rapid growth and buildup of new skin cells.
Psoriasis may appear on any part of the body, though the lesions most commonly develop on the elbows, hands, feet, knees, and scalp. Seborrheic dermatitis, on the other hand, is a skin condition that causes scaling and itchiness on the scalp and face. Seborrheic dermatitis is also commonly known as dandruff.
Seborrheic Dermatitis (Dandruff) Symptoms
Seborrheic dermatitis usually occurs on the scalp, though any part of the body can become affected.
