What should you know about cradle cap what causes it?

In early life, oil glands can produce oily material that sticks skin cells together as scale. A yeast that normally lives on skin may also contribute to inflammation when the scalp environment supports it. Babies differ in how much oil and scale they produce, so the condition can vary in colour and thickness. Cradle cap is not considered a sign that the scalp is dirty, and routine washing does not prevent every case. It is also not the same as an allergy to a caregiver or a result of poor parenting.

Wash with a mild baby shampoo and massage with fingertips rather than nails. Let loose scale come away naturally; do not scratch or peel attached patches. For thick scale, a clinician may advise [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) to soften it before washing. If inflammation is persistent or yeast is thought to contribute, discuss [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) rather than choosing an adult product yourself. Avoid fragranced products if they make the skin more irritated.

Get medical advice if the scalp is very red, cracked, painful, swollen, wet, or producing pus-like material. A rash that spreads to the body, causes significant itching, or does not respond to gentle care may need a different diagnosis. Fever, poor feeding, or a baby who seems unusually unwell warrants prompt assessment because these features are not explained by simple scale alone.

Ask which features support cradle cap, whether another condition should be ruled out, how to soften the scale safely, and when treatment is needed.
