Scalp Psoriasis

Seborrheic scalp psoriasis may resemble severe dandruff. Patches of thick, flaky skin may extend to the forehead below the hairline. Scales may build up in the outer ear. The face itself is usually unaffected; this is an important feature in the diagnosis of scalp psoriasis due to the fact that with rosacea you can have episodes of seborrheic dermatitis. Seborrheic dermatitis involves overactive sebaceous glands, which cause inflammation, flaking and a red rash in the central portion of the face. If one looks closely, the flakes usually have a greasy look, smell and feel.
