What should you know about Mustela oil for cradle cap?

Cradle cap is a common form of infantile seborrhoeic dermatitis. It causes greasy or dry scales on the scalp and may extend to the eyebrows or behind the ears. Babies are usually not distressed by it. The appearance does not mean the scalp is dirty, and vigorous brushing can create soreness or tiny breaks in the skin.

Apply a small amount of oil to the affected scalp for a short period to loosen scales, following the product directions. Massage lightly with fingertips, then wash the hair with a mild baby shampoo and use a soft brush only for scales that lift easily. Do not pick, scrape, or use essential oils. If moisturising care is needed, [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) may be discussed with a clinician; [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) should be used only when advised.

Contact a healthcare professional if the scalp is swollen, hot, bleeding, weeping, crusted, very itchy, or has an unpleasant smell. Arrange assessment if the rash spreads widely, your baby seems unwell, or gentle care is not helping. Avoid leaving oil on for long periods if it makes the scalp more irritated.
