Seborrheic dermatitis causes greasy flakes and redness around the nose, brows and scalp. Why it happens, how it differs from dry skin, and treatments with evidence like ketoconazole.
Seborrheic dermatitis is rising in searches, often from people who think they have stubborn dry skin. It shows up as flaky, sometimes greasy patches with redness, around the sides of the nose, eyebrows, hairline, ears and scalp, where it is better known as dandruff.
It can be controlled but not cured, so most people use a treatment when it flares and a lighter routine to keep it away.
Use a gentle cleanser, avoid heavy oils on affected areas, and choose a light moisturizer. Stress, cold weather and lack of sleep can trigger flares.
If it spreads, doesn’t improve with over-the-counter treatment, or you’re not sure of the diagnosis, a dermatologist can confirm it. Psoriasis, rosacea and eczema can look similar.
Seborrheic dermatitis is linked to an inflammatory reaction to Malassezia, a yeast that lives on oily skin. That is why antifungal treatments help. A Cochrane review found ketoconazole and ciclopirox more effective than placebo.
