Cradle cap: what it is, how long it lasts and how to treat it
Spotting crusty, flaky patches on your newborn's scalp can feel alarming, but cradle cap is one of the most common and harmless skin conditions babies get. It needs no urgent treatment, usually sorts itself out within a few months, and does not bother your baby at all. This article walks through what cradle cap is, what it looks and feels like, how you can manage it gently at home, and the handful of signs that are worth a call to your GP.
What is cradle cap?
Cradle cap is a very common skin condition that affects babies, particularly in the newborn months. Medically it falls under the category of seborrhoeic dermatitis, but in babies it is almost always mild and short-lived. It is not caused by poor hygiene, and it is not something your baby caught from anyone else. The precise reason some babies develop it is not fully understood, but what is clear is that it is harmless and will resolve on its own in time.
Because it cannot spread between babies, there is no need to keep your little one away from other children or change your routine around it. You do not need any prescription treatments in the vast majority of cases.
What does cradle cap look like?
The most recognisable sign is patches of greasy, scaly skin, most often on the scalp. The scales are typically white or yellow in colour and have a crusty texture. They may loosen and flake off, which can look a little like dandruff.
On lighter skin tones, the skin beneath the scales can appear pink or red. On darker skin tones, the affected area may look lighter or darker than the surrounding skin. Both are normal variations of the same condition.
While the scalp is the most common site, cradle cap can also appear on the face, particularly around the eyebrows and nose. In some babies it shows up in skin fold areas or the nappy region. Wherever it appears, the look is the same: greasy, scaly patches that may flake.
One thing that can surprise parents is finding loose hair coming away along with the scales. This is normal and the hair will grow back once the condition has cleared.
How long does cradle cap last?
Most cases of cradle cap clear up on their own within a few months. Some babies see it resolve sooner, while for others it takes a little longer. In either case, the condition is not causing your baby any discomfort or pain, so there is no urgency to get rid of it quickly.
Knowing it will pass on its own can make the waiting easier, but there are gentle steps you can take in the meantime to help manage the appearance of the scales if you would prefer to.
How to treat cradle cap at home
Home care for cradle cap is gentle and straightforward. The goal is to soften and loosen the scales rather than scrubbing or picking at them, which can irritate the skin and risk infection.
- Apply an emollient or coconut oil. Massage a small amount gently into the affected area on your baby's scalp. This helps soften the scales and makes them easier to lift. Leave it to soak in for a short while before the next step.
- Use a soft brush. After the oil has had time to work, use a very soft baby brush to gently lift the loosened scales from the scalp. Take your time and keep the pressure light.
- Wash with baby shampoo. Follow the brushing with a gentle wash using a mild baby shampoo. This removes any remaining oil and loose scales.
- Bathe regularly with water and emollient. For day-to-day care, bathing your baby in water with an emollient instead of soap helps keep the skin comfortable and supports natural clearing.
- Barrier cream for the nappy area. If cradle cap has appeared in the nappy region, applying a barrier cream can help protect the skin there.
The routine above can be repeated as often as feels helpful, though gentle and consistent care works better than vigorous scrubbing. The scales will loosen over time.
What to avoid
Some products that seem helpful at first glance are best left off a baby's scalp entirely. The NHS is clear that you should avoid the following:
- Olive oil and peanut oil. These are not recommended for baby skin and may cause irritation or sensitisation.
- Adult shampoos and fragranced products. Baby skin is much more sensitive than adult skin, and products made for adults can be too harsh and cause further irritation.
- Picking at the crusts. It can be tempting to try to peel the scales off, but doing so risks breaking the skin, which could lead to infection.
When to see your GP
Cradle cap nearly always resolves without any medical input, but there are a few situations where it is worth getting a professional opinion:
- The condition has not improved after several weeks of home care.
- The scales or patches have spread to cover most of your baby's body rather than staying on the scalp and face.
- The crusts are bleeding or leaking fluid.
- The affected skin looks swollen or inflamed beyond the usual redness.
These signs could point to an infection, or to a different skin condition such as atopic eczema or scabies, which your GP will be able to assess and advise on.
Frequently asked questions
What does cradle cap look like?
Cradle cap appears as patches of greasy, scaly skin, most commonly on a baby's scalp and face. The scales are white or yellow and crusty and may flake off. The skin beneath can look pink or red on lighter skin tones, or lighter or darker on darker skin tones.
How long does cradle cap last?
Cradle cap usually clears on its own within a few months. It does not cause any pain or discomfort, so even while it is present your baby is completely comfortable.
Can I treat cradle cap at home?
Yes. Massaging an emollient or coconut oil into the scalp to soften the scales, then using a soft brush to gently lift them before washing with a mild baby shampoo, is the recommended approach. Regular bathing in water with an emollient instead of soap also supports clearing.
Is cradle cap contagious?
No. Cradle cap cannot spread from one baby to another. The cause is not fully known, but the condition has nothing to do with hygiene or contact with others.
When should I see a doctor about cradle cap?
See your GP if home care has not improved things after a few weeks, if the condition spreads across most of the body, if crusts bleed or leak fluid, or if the affected skin looks swollen. These signs may indicate infection or another skin condition that needs assessment.
