Seborrheic dermatitis is a common, inflammatory skin condition that causes flaky, white to yellowish scales to form on oily areas such as the scalp or inside the ear. It can occur with or without reddened skin.
Causes, incidence, and risk factors
Seborrheic dermatitis is thought to be due to a combination of an over production of skin oil and irritation from a yeast called malassezia.
Seborrheic dermatitis appears to run in families. Stress, fatigue, weather extremes, oily skin, infrequent shampoos or skin cleaning, use of lotions that contain alcohol, skin disorders (such as acne), or obesity may increase the risk.
Neurologic conditions, including Parkinson's disease, head injury, and stroke may be associated with seborrheic dermatitis. Human immunodeficiency virus (HIV) has also been linked to increased cases of seborrheic dermatitis.
Seborrheic dermatitis can occur on many different body areas. Usually it forms where the skin is oily or greasy. Commonly affected areas include the scalp, eyebrows, eyelids, creases of the nose, lips, behind the ears, in the outer ear, and middle of the chest.
In general, symptoms of seborrheic dermatitis include:
Plaques over large area
Greasy, oily areas of skin
Skin scales -- white and flaking, or yellowish, oily, and adherent -- "dandruff"
Itching -- may become more itchy if infected
Signs and tests
The diagnosis is based on the appearance and location of the skin lesions.
You can treat flaking and dryness with over-the-counter dandruff or medicated shampoos. Shampoo the hair vigorously and frequently (preferably daily). Loosen scales with the fingers, scrub for at least 5 minutes, and rinse thoroughly. Active ingredients in these shampoos include salicylic acid, coal tar, zinc, resorcin, ketoconazole, or selenium.
Shampoos or lotions containing selenium, ketoconazole, or corticosteroids may be prescribed for severe cases. To apply shampoos, part the hair into small sections, apply to a small area at a time, and massage into the skin. If on face or chest, apply medicated lotion twice per day. Recently, creams classified as topical immune modulators are being used.
Seborrheic dermatitis may improve in the summer, especially after outdoor activities.
Seborrheic dermatitis is a chronic (life-long) condition that can be controlled with treatment. It often has extended inactive periods followed by flare-ups. A more extreme form of this condition overlaps with psoriasis of the scalp and is called sebopsoriasis.
Psychological distress, low self esteem, embarrassment
Secondary bacterial or fungal infections
Calling your health care provider
Call for an appointment with your health care provider if seborrheic dermatitis symptoms do not respond to self-care or over-the-counter treatments.
Also call if patches of seborrheic dermatitis drain fluid or pus, form crusts, or become very red or painful.
The severity of seborrheic dermatitis can be lessened by controlling the risk factors and by paying careful attention to skin care.
Seborrheic dermatitis does not cause hair loss.
