Seborrheic Dermatitis

What is seborrheic dermatitis?

Seborrheic dermatitis is an inflammation of the upper layers of skin, characterized by red, itchy skin that sheds scales. A hereditary condition, seborrheic dermatitis is often aggravated by cold weather conditions.

Seborrheic dermatitis is most common during:

infancy
In infants, the condition is also called "cradle cap," because of its characteristic scaly appearance on the scalp. However, cradle cap can also occur in the diaper area. Seborrheic dermatitis in this age group usually clears up on its own within the first year.

middle age
When seborrheic dermatitis occurs at this age, the condition is usually more intermittent.

old age
When seborrheic dermatitis occurs at this age, the condition is usually more intermittent.

Persons with oily skin or hair are more at risk for developing seborrheic dermatitis.

What are the symptoms of seborrheic dermatitis?

The following are some of the other symptoms associated with seborrheic dermatitis. However, each person may experience symptoms differently:

itching scalp

dry or greasy scales on the scalp

a yellow or red scaly rash along the hairline, behind the ears, in the ear canal, on the eyebrows, around the nose, and/or on the chest

The symptoms of seborrheic dermatitis may resemble other dermatologic conditions. Consult a physician for diagnosis.

How is seborrheic dermatitis diagnosed?

A complete medical history and physical examination helps the physician in diagnosing seborrheic dermatitis.

Treatment for seborrheic dermatitis:
Although the condition is treatable, it may recur. Treatment is usually effective in alleviating symptoms and may include:

rubbing mineral oil on the head of infants with a soft toothbrush, followed by a gentle shampooing

corticosteroid cream or lotion

medicated shampoo for adults, such as nonprescription shampoos containing tar, pyrithione zinc, selenium sulfide, sulfur, or salicylic acid, or prescription shampoos
