Symptoms

Seborrheic dermatitis (seb-o-REE-ik der-muh-TI-tis) is a common skin disorder that mainly affects your scalp, causing scaly, itchy, red skin and stubborn dandruff. In infants, seborrheic dermatitis of the scalp is known as cradle cap. Seborrheic dermatitis can also affect your face, upper chest, back and other areas of your body that have many oil (sebaceous) glands.

Causes

• A yeast (fungus) called Malassezia. This fungus is one of the normal microscopic life forms that grow, along with certain bacteria, in your skin's oily secretion (sebum). Creams, foams or lotions containing an antifungal agent, such as ketoconazole (Ketozole, Extina), often help reduce flare-ups, supporting the idea that this yeast is a contributing factor. But seborrheic dermatitis itself isn't considered an infection, and it's not contagious.
• Change of season. Episodes are often worse in winter.
• Neurological conditions. Seborrheic dermatitis may occur more frequently in people who have *Parkinson's disease and certain other neurological disorders.
• Stress and fatigue. Stressful life events and situations may help trigger an episode or make it worse through mechanisms that aren't yet understood. The role of neurological disorders and stress may be related through effects on the nervous system.
• HIV/AIDS. Seborrheic dermatitis may occur more commonly and tend to be more severe in those with HIV/AIDS.
