Seborrheic dermatitis is a red, scaly rash in oily or hair-bearing areas such as the eyebrows, creases beside the nose, hairline, scalp, and behind the ears. It is often associated with a yeast called Malassezia. Seborrheic dermatitis is found worldwide and in both males and females.

The condition is often made worse by hot, humid weather or when the seasons change. Treatment is usually with antifungal creams such as Lotrimin (clotrimazole) or Nizoral (ketoconazole).

Scalp treatment can include selenium sulfide/sulfur shampoo, zinc pyrithione shampoo, or ketoconazole (Nizoral) shampoo. While the rash may clear with treatment, the condition can come back.

If seborrheic dermatitis does not clear up, see your doctor. Certain medical conditions or medications can cause or worsen seborrheic dermatitis. In some cases, you ay need oral (by mouth) prescription medication.
