Seborrheic Dermatitis



The exact cause is not known. Common skin yeast organisms or genetics may play a role.

Risk Factors

This problem is more common in men. Other things that may raise the risk are:

  • Having a weakened immune system due to things like HIV infection or a recent organ transplant
  • Chronic health problems, such as hepatitis C
  • Genetic diseases, such as Down syndrome



Problems may be mild to severe. Symptoms may also come and go over time.

The skin may have:

  • Patchy scales that may look greasy or moist
  • Yellow to white scales that flake off
  • Redness
  • Itching and burning
  • Small pimples on the nose, eyebrows, chest, back, arm pits, or genitals

Newborns may have a thick, yellow, crusted scalp rash known as cradle cap.


The doctor will ask about your symptoms and health history. A physical exam will be done. It will focus on the rash. This is often enough to make the diagnosis. You may need to see a doctor who treats skin problems.



There is no cure. The rash may get better on its own in children. Baby shampoo, mineral oil, and anti-fungal shampoos can help.

In others, the goal of treatment is to manage symptoms. Choices are:

  • Prescription or over the counter shampoos
  • Prescription or over the counter creams or lotions that contain:
    • Hydrocortisone or other cortisone (steroid) preparations
    • Antifungal medications
    • Antibiotic medication
    • Pimecrolimus or tacrolimus
    • Lithium salt
