If you have noticed greasy yellow or white flakes on your baby’s scalp, you are almost certainly looking at cradle cap, one of the most common skin conditions of early infancy. It can look alarming the first time you see it, especially on a newborn whose skin otherwise seems perfect. In this guide we explain what it is, how to care for it gently at home using official health guidance, what not to do, and the signs that mean it is time to see a doctor.
The short version is reassuring. Health services in Singapore and the UK describe it as common and usually harmless, and most babies outgrow it in the first year. It is not caused by poor hygiene and it does not spread from one baby to another.
The catch is that well meaning advice often goes too far. Picking at crusts or using adult or medicated shampoo can make a mild problem worse. Official sources recommend a gentle, patient routine.
Everything below is general guidance drawn from official health sources, linked throughout. It is not a substitute for your own doctor’s advice.
What cradle cap actually is
The medical name for the condition is infant seborrhoeic dermatitis. When it affects a baby’s scalp, it is known by its everyday name. The Families for Life newborn skin guide, contributed by SingHealth, describes it as a common skin condition in infants that typically appears before three months of age.
It usually shows up as:
- greasy, scaly patches on the scalp, sometimes forming thick yellow or white crusts;
- flaking that can spread to the eyebrows, behind the ears, the back of the neck and the nappy area;
- skin underneath that may look pink or red on lighter skin, or a slightly different shade from the surrounding skin on darker skin.
According to the NHS guidance on the condition, it typically does not seem to bother the baby. Some sources mention mild itching, so if your baby seems uncomfortable or keeps rubbing the area, mention it to your doctor.
What causes it
Nobody knows the exact cause. The SingHealth-adapted guidance links it to oil glands that are overactive after birth, possibly because of hormones from the mother, together with a yeast called Malassezia that lives naturally on the skin. The US National Library of Medicine’s MedlinePlus page is clear on two points parents worry about most: it is not contagious, and it is not caused by poor hygiene. You have not done anything wrong.
Is it serious? What the official sources say
For the vast majority of babies, no. MedlinePlus states plainly that it is not dangerous. The Families for Life guide says most infants outgrow it by 6 to 12 months of age, while MedlinePlus notes that in some children it can last longer, occasionally until age two or three.
There is one longer term point worth knowing. The SingHealth-adapted guidance notes that some babies with this kind of scalp scaling go on to develop eczema, particularly where there is a family history of eczema, allergic rhinitis or asthma. That is not a reason to panic, but it is useful information to share with your paediatrician at routine checks if eczema runs in the family.
Hair can come away with the scales as they lift. The NHS describes this as normal and says the hair grows back.
Gentle home care, step by step
Most cases are managed at home. The routine below follows the official guidance from SingHealth (via Families for Life), the NHS and MedlinePlus.
- Soften the scales first. For thicker crusts, gently massage a little oil or emollient into the scalp and leave it for a while before washing. The Families for Life guide suggests 30 to 60 minutes. See the note on oils below before choosing one.
- Loosen with a soft brush or your fingertips. Use slow, light circles with a soft baby brush or a soft towel. Never scrape.
- Wash with a mild baby shampoo. Use a mild, tear-free baby shampoo and rinse thoroughly so no oil or shampoo is left behind. MedlinePlus suggests daily gentle shampoos while scales are present.
- Brush away what lifts easily. After washing, flakes that have loosened can be brushed out gently. Leave any that are still stuck for another day.
- Repeat patiently. Improvement can take days to weeks, not one bath.
If the flaking is on other parts of the body, the NHS suggests bathing your baby regularly with water and an emollient rather than soap. Where the nappy area is affected, change wet or dirty nappies promptly, and a pharmacist can recommend a suitable barrier cream. Our guide to preventing nappy rash has more.
A note on which oil to use
Official advice differs here, and we would rather tell you that than pretend otherwise. The SingHealth-adapted Families for Life guide suggests olive oil to soften thick scales. The NHS suggests an emollient or coconut oil, and advises against olive oil because it may not suit baby skin, and against peanut oil because of the allergy risk. If you are unsure, ask your doctor or a pharmacist which product suits your baby, and avoid any nut-based oil.
Fitting it into bath time
Scalp care slots into your normal bath routine. Our guide to bathing a newborn safely covers water temperature, holding and drying.
What not to do
It is easy to do too much rather than too little. The official sources are consistent on these points.
- Do not pick or scratch off the crusts. Both the SingHealth-adapted guidance and the NHS warn that picking may increase the risk of infection.
- Do not use adult shampoo or soap on the scalp. The NHS advises against both.
- Do not use medicated or dandruff shampoos unless a doctor prescribes one. Adult products for seborrhoeic dermatitis contain active ingredients meant for adults. If your baby needs something stronger, a doctor can decide.
- Avoid fragranced products. The NHS advises against products containing fragrance or perfume. Choose gentle, fragrance-free cleansers and oils where possible.
- Avoid nut oils. The NHS specifically warns against peanut oil because of the allergy risk.
When to see a doctor about cradle cap
The NHS advises seeing a GP if:
- it has not improved after a few weeks of home care;
- it spreads all over the body;
- the crusts bleed or leak fluid;
- the affected areas look swollen.
MedlinePlus adds that you should contact a doctor if patches drain fluid or pus, form crusts, or become very red or painful, or if your baby develops a fever. Bleeding, fluid or swelling can point to an infection or a different condition, such as eczema, which needs a proper diagnosis.
In Singapore, your family GP, polyclinic or paediatrician is the right first stop for a persistent rash. For severe cases, the Families for Life guide notes that a doctor may prescribe an antifungal shampoo, a mild steroid lotion or a moisturiser. These are prescription decisions, so do not try to replicate them with products from your own cabinet.
A scalp rash on its own is not an emergency. But if your baby has a fever, is unusually drowsy or floppy, is feeding poorly or seems unwell in any other way, see a doctor promptly. Our guide to newborn fever explains which temperatures need urgent attention. If your baby has difficulty breathing, will not wake or you are otherwise worried about an emergency, call 995 straight away.
How a helper or confinement carer can help
In many Singapore households, bath time is shared between parents, grandparents and a live-in helper or confinement carer. That is helpful, as long as everyone is doing the same thing.
A few simple habits keep everyone aligned:
- Agree one routine and write it down. Note which oil or emollient, how long it stays on, which shampoo and how often. A short note near the bath area works well.
- Parents choose the products. Anyone helping with care should use only what the parents or the baby’s doctor have approved, and should never introduce a new oil, cream or home remedy without asking.
- Report changes early. Ask whoever bathes the baby to tell you if the patches spread, bleed, ooze, look swollen or if the baby seems unwell, so you can decide whether to see a doctor.
- Keep the tools gentle and clean. A dedicated soft baby brush and clean towels for the baby are enough.
If you are planning extra help for the newborn months, our page on live-in help for newborn and confinement care explains how we match helpers, and our article on building a childcare routine with your helper shows how to divide daily tasks clearly. Families who are setting up from scratch may also find our newborn essentials checklist useful.

Frequently Asked Questions
Is cradle cap caused by not washing my baby’s hair enough?
No. Official sources, including MedlinePlus from the US National Library of Medicine, state that the condition is not caused by poor hygiene. Gentle washing with a mild baby shampoo helps manage it, but a lack of washing did not cause it.
Is it contagious to other children in the house?
No. It does not spread from person to person, so siblings, cousins and other babies cannot catch it.
How long does it take to go away?
It varies. Singapore guidance adapted from SingHealth says most infants outgrow it by 6 to 12 months of age, and many cases settle much sooner with gentle care. In some children it lasts longer. If there is no improvement after a few weeks of home care, or it is spreading, see your doctor.
Can I use olive oil or coconut oil on my baby’s scalp?
Official advice differs. The SingHealth-adapted Families for Life guide suggests olive oil to soften thick scales, while the NHS suggests an emollient or coconut oil and advises against olive oil and peanut oil. The safest approach is to ask your doctor or pharmacist which product suits your baby, avoid nut oils, and wash the oil out after softening.
Should I use a dandruff shampoo on my baby?
Not unless a doctor prescribes one. Adult medicated and dandruff shampoos contain active ingredients intended for adults, and the NHS advises against adult shampoos for babies. If gentle care is not enough, a doctor may prescribe a suitable antifungal shampoo, mild steroid lotion or moisturiser for your baby.
Conclusion
Scaly patches on a baby’s scalp are common, usually harmless and not a sign that anything has been done wrong. The official approach is simple: soften the scales, brush gently, wash with a mild baby shampoo and give it time. Avoid picking, adult products, fragrance and nut oils, and ask a pharmacist or doctor when you are unsure which oil or emollient to use.
See a doctor if it is not improving after a few weeks, if it spreads widely, or if the skin bleeds, oozes or swells. If your baby has a fever or seems unwell, get medical advice promptly, and call 995 in an emergency.
