The short answer
White or yellow greasy scales on your baby’s scalp may be cradle cap. It is common in the first months, is not caused by poor care, and usually does not bother a baby. Gentle washing with mild shampoo may help. Do not pick the crusts; ask a clinician about bleeding, fluid leakage, or swelling.

Keep in mind
- Cradle cap does not mean inadequate care; recurrence is not a failure.
- Do not pick crusts or try to remove every scale at each bath.
- Ask a clinician about bleeding, leakage, or swelling.
What does cradle cap look like, and why does it happen?
Cradle cap is greasy scaling and crusting of the scalp, medically called seborrheic dermatitis. It may appear as fine flakes or thicker scales attached to the skin. Surrounding skin may look pink or red on lighter skin, or lighter or darker than usual on darker skin.
It often begins between about three weeks and two months after birth. Its exact cause is uncertain; responses to naturally occurring skin yeasts and maternal hormones stimulating oil glands are possible explanations. It is not contagious or caused by poor hygiene or a food allergy. Cradle cap alone does not require removing foods from your baby's diet or your own.
What does gentle care involve?
Wash with a mild, fragrance-free baby shampoo. Massage lightly with your fingertips and use a soft baby brush for loosened flakes. Do not lift attached crusts with your nails or brush firmly; picking can increase infection risk.
A few thin flakes may come away in the bath while a thicker crust stays. You can finish without repeatedly rubbing that patch. Every bath does not need to remove all the scales.
Shampooing every other day may help many babies. If your baby has eczema or another skin condition, discuss washing frequency with their pediatrician. Do not start medicated shampoo on your own.
Is oil or another product necessary?
Start with gentle washing and light massage. If scales do not loosen easily, ask a pharmacist or clinician about a suitable emollient. Choose a product appropriate for your baby's skin and clarify its use rather than applying any household oil.
Avoid olive oil and peanut oil, as well as soap, adult shampoo, and fragranced products.
There is no single leave-on time suitable for every product. Follow its instructions or professional advice and shampoo the scalp afterward. A clinician should choose the product and duration if a steroid or antifungal cream is needed.
When should you ask the pediatrician?
Seek advice if crusts bleed, leak fluid or pus, smell unpleasant, or the skin is swollen. Significant itching, pain, distress, or hair loss also needs assessment. Do not assume these are ordinary cradle cap and intensify cleaning.
Similar patches may occur around the eyebrows, ears, or skin folds. Discuss spread beyond the scalp or lack of improvement after several weeks of care. Do not use scalp brushing techniques on the face or skin folds.
Cradle cap often eases over weeks or months. It may last beyond three months or recur; most cases clear by about one year. A few hairs can come away with scales and regrow, but show significant hair loss to a clinician.
What can you try today?
1. Look at the scalp. Ask a clinician about discharge, swelling, bleeding, or marked discomfort instead of trying to clean it away.
2. Without warning signs, start with mild baby shampoo and gentle massage at the next wash.
3. Use a soft baby brush for easily loosened flakes and leave attached crusts alone.
4. If an emollient is needed, ask a pharmacist or clinician which product suits your baby and how to use it.
When to seek support
Some signs need emergency help; other concerns can be discussed with your child’s healthcare team.
- Bleeding, discharge, swelling, or an unpleasant smell.
- Significant itching, pain, distress, hair loss, spreading patches, or no improvement after several weeks of care.
