Quick Answer
Cradle cap is scaly or flaky skin on the scalp (infant seborrheic dermatitis). AAP guidance says it is common, harmless, and not contagious, and it usually clears with gentle washing. CDC and Health Canada guidance recommend routine skin care and clinician follow-up if rashes spread, ooze, or seem painful.
What Parents Need to Know
Cradle cap can look dramatic but often does not bother baby.
It may appear in the first weeks, improve, and sometimes return briefly during infancy.
Picking or scraping scales can cause bleeding and infection—gentle care works better.
Evidence-Based Guidance
AAP cradle cap guidance describes:
- Greasy yellow or brown scales on the scalp
- No itching in many babies
- Gradual improvement over weeks to months
- Gentle shampooing and soft brushing as first-line care
AAP bathing and skin care guidance recommends:
- Short baths with mild, fragrance-free cleansers
- Patting skin dry without rubbing
- Moisturizing dry patches if your clinician agrees
- Avoiding adult dandruff shampoos unless your pediatric clinician suggests them
CDC infant care guidance for parents encourages:
- Routine hygiene and diaper area care
- Watching for spreading, blistering, or oozing rashes
- Calling a healthcare provider when skin changes accompany fever or poor feeding
Health Canada child and infant health resources advise:
- Monitoring skin changes over time
- Seeking professional advice when symptoms worsen or affect comfort and sleep
Practical Steps
- Wash hair every few days with mild baby shampoo.
- Massage scalp gently with fingertips during the bath.
- Brush softly after bathing to loosen flakes.
- Apply a small amount of mineral oil or petroleum jelly before shampoo only if your clinician recommends it—avoid slippery handling.
- Do not scratch or use sharp tools to remove scales.
- Track changes with photos if scales spread beyond the scalp.
