Why does cradle cap happen?

Cradle cap is also called infantile seborrheic dermatitis. It commonly appears as yellow, white, or brownish flakes that cling to the scalp, sometimes with mild redness. The scales can look thick because oil holds loose skin cells together. Cradle cap is not caused by poor hygiene, and ordinary shampooing does not always remove the build-up immediately.

The same tendency toward oiliness can affect the eyebrows, behind the ears, or skin folds. A baby may have no discomfort, although some infants seem itchy or unsettled. Cradle cap is different from an infection caused by unclean surroundings, and vigorous scrubbing can irritate delicate skin.

Wash the scalp with a mild baby shampoo, then gently massage the lather over the affected area. A soft baby brush can lift loosened flakes after washing; do not pick, scratch, or pull scales that are still attached. If the scalp remains dry or the scales are stubborn, a clinician may suggest an emollient approach to soften them before washing.

Stop any product that causes redness or stinging. Avoid adult dandruff products, essential oils, and medicated creams unless a healthcare professional has recommended them for your baby. If the appearance extends beyond the scalp or does not settle with gentle care, a clinician can check whether another skin condition is present and discuss options such as topical antifungal treatment when appropriate.

Arrange a clinical assessment if the skin is very red, swollen, cracked, bleeding, oozing, or develops crusting that does not look like simple scale. Seek advice if your baby seems in pain, has a fever, is feeding poorly, or the rash is spreading quickly. A healthcare professional can distinguish cradle cap from eczema, psoriasis, contact irritation, or an infection and choose an age-appropriate treatment.

Bring the names of products used on the scalp and mention when the changes began. Do not share prescription or antifungal treatment between children, even if the rash looks similar.

Ask whether the scalp changes fit cradle cap, which cleanser or emollient is suitable for your baby's age, and how often to use it. You can also ask which signs would mean the skin needs review and whether affected areas outside the scalp need separate care.
