Picture of Yellow Dandruff
Seborrheic dermatitis causes oily, flaky yellowish patches of skin on the head and face. The area may also be affected by skin redness. The condition is benign, but it can produce severe itching. If an affected person scratches the skin too hard, it may break the skin and lead to an infection. If the scalp has silvery scales, psoriasis may be the cause.
