Seborrheic dermatitis is a very common skin condition which presents with itchy, red patches of skin, greasy scales, and flaking. Common areas of involvement include the scalp, ears, eyebrow region, and sides of the nose. It typically occurs in infants younger than 3 months of age and in adults ages 30-60. In infants, the condition is commonly referred to as “cradle cap.” When occurring on the scalp in adolescents and adults, seborrheic dermatitis is often called “dandruff.” The exact cause of the condition is unknown, but Malassezia (a yeast commonly found on our skin), excess oil production, or an immune mediated response may be contributing factors. Though the condition is chronic, treatment options are available including dandruff shampoos and topical medications.
