Seborrheic Dermatitis Symptoms & Diagnosis

Symptoms

The symptoms of seborrheic dermatitis can vary from mild to severe. They include:

• Dry or greasy scaling of the scalp
• Itchy scalp
• Itchy, scaly rash with small pimples
• Thickened, flaking skin
• Reddened skin over the forehead and on either side of the nose

In babies less than one month old, seborrheic dermatitis may cause a thick, yellow, crusted scalp rash known as "cradle cap."

Diagnosis

The doctor will ask about your symptoms and medical history, and perform a physical exam. You may be referred to a doctor who specializes in skin disorders (a dermatologist).
