What should you know about cradle cap behind ear?

Cradle cap may cause flaky or greasy scale behind the ear and where the ear meets the scalp. Moisture from bathing, sweat, saliva, or hair can remain in the fold, leaving mild redness or soft scale.

Irritant dermatitis, eczema, or a skin infection can also affect this area. Pain, warmth, swelling, bad smell, discharge, or cracks are more concerning than uncomplicated dry scale. Do not push swabs into the ear canal; the skin behind the ear is the area to observe.

Rinse the fold with lukewarm water and a mild cleanser, then pat it dry carefully. If recommended by a clinician, a thin layer of plain emollient can soften scale on the outer skin; avoid coating a wet or broken area. Do not pick attached flakes or use essential oils. A clinician may recommend [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) or consider [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) if the findings fit.

Have the area assessed if redness persists, the fold cracks, or the rash becomes painful, swollen, warm, wet, or foul-smelling. Seek prompt care for pus, fever, redness spreading onto the face, or a child who seems unwell. Discharge from inside the ear or new trouble hearing is not typical cradle cap and needs medical attention.

Ask whether the fold is irritated or infected, which product is safe on the outer ear skin, and how often to clean and dry it. Tell the clinician about ear discharge, scratching, recent bathing products, and whether the rash affects the scalp or other folds.
