Dandruff, the scaly flakes of skin that shed and fall on your clothing, is actually just one symptom of seborrheic dermatitis. Others include itchy skin, sores, redness, and even hair loss. If you're bothered by dandruff and other symptoms of seborrheic dermatitis, talk to a dermatologist. He or she can recommend medicated shampoos and other treatments to help you manage this condition.
Seborrheic dermatitis is called cradle cap when it occurs in an infant or small child. The scalp, as well as skin on the face and groin, may develop patches of crusty, discolored skin. Cradle cap is usually a temporary condition.
