What is seborrheic dermatitis?
Seborrheic dermatitis is an inflammation of the upper layers of skin, characterized by red, itchy skin that sheds scales. Seborrheic dermatitis may be a hereditary condition. It is often aggravated by hormonal changes and 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 happen 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 happens at this age, the condition is usually more intermittent and called dandruff.
Old age. When seborrheic dermatitis happens at this age, the condition is usually more intermittent. It becomes less common after 60 years of age.
People with oily skin or hair are also 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. Symptoms may include:
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, in creases on the arms, legs, or groin, and/or on the chest.
The symptoms of seborrheic dermatitis may resemble other skin conditions. Always talk with your healthcare provider for a diagnosis.
How is seborrheic dermatitis diagnosed?
A complete medical history and physical exam helps the healthcare provider in diagnosing seborrheic dermatitis.
