Key facts
Cradle cap at a glance.
The essentials, in plain English - what it is, who it affects and how it is treated in the UK today.
-
What it is
Infantile seborrhoeic dermatitis - a benign, self-limiting inflammatory scalp condition in babies with greasy yellow-white scales.
-
Who it affects
Infants from about 2 weeks to 12 months old, peaking around 3 months and usually settling by the first birthday.
-
What causes it
A mix of maternal androgens stimulating sebum, Malassezia yeast overgrowth and a mild inflammatory response - not poor hygiene.
-
Is it contagious
No - and it is not a sign of allergy or neglect. Babies are usually comfortable and feed and sleep normally.
-
First-line care
Regular gentle washing with a mild baby shampoo, softening with an emollient and lifting scales with a soft brush.
-
When to treat
Persistent, widespread or inflamed cases may need topical antifungal or short-course mild steroid under medical advice.
Why this guide matters
A gentle plan, and clear reasons to escalate.
Cradle cap looks alarming to a new parent and is almost always harmless. The three points below shape the rest of the page.
-
It is benign and self-limiting
For nearly every baby the condition settles by the first birthday - without any long-term consequences for skin or hair.
-
Simple care is usually enough
Gentle washing, an emollient soak and a soft brush handle the vast majority of cases. Medication is the exception, not the rule.
-
A few situations need a clinician
Severe, widespread, inflamed or persistent rash - or an unwell baby - deserves prompt review rather than more home remedies.
How the diagnosis is made
From first flakes to a clear plan.
The steps a UK GP, health visitor or paediatrician will normally follow, in order - so you know what to expect and why.
Phase 1 · Assessing
History, examination and comfort
Phase 2 · Confirming
Ruling out mimics and targeted tests
Phase 3 · Planning
Red flag review and family plan
- 01
Assessing
Clinical history
Age of onset, distribution of scales, sleep, feeding and whether the baby seems bothered by the rash.
- 02
Assessing
Skin examination
A careful look at the scalp, face, eyebrows, ears, neck folds and nappy area for the typical greasy yellow-white plaques.
- 03
Assessing
Check for distress or itch
Cradle cap is usually painless and non-itchy - a scratching, unsettled baby points more toward atopic eczema.
- 04
Confirming
Rule out mimics
Consider atopic eczema, tinea capitis, infantile psoriasis, scabies and, rarely, Langerhans cell histiocytosis.
- 05
Confirming
Targeted tests if atypical
Scalp brushings for fungal culture if tinea is suspected, or scrapings for scabies - only when the picture does not fit.
- 06
Planning
Red flag review
Failure to thrive, severe or refractory disease or systemic upset triggers specialist paediatric or dermatology input.
- 07
Planning
Family plan
Set expectations - most cases settle by 12 months - and agree a simple, step-up routine parents can actually follow.
Typical timeline: most families get a confident diagnosis and plan in a single visit.
Symptoms
What cradle cap actually looks like.
The classic mix of greasy yellow-white scales on the scalp - and the features that mean it is time to check in with a clinician.
-
Greasy yellow-white scales
Thick, adherent flakes on the crown and back of the scalp - sometimes brown or crusted where scales have built up.
-
Well-defined plaques
Patches with a slightly oily sheen, more visible than felt - the underlying skin is usually only mildly red.
-
Face and T-zone involvement
The forehead, eyebrows and creases around the nose can show the same greasy scale as the scalp.
-
Behind and inside the ears
A common site that is easy to miss - look in the folds and the ear canal opening for flaky, greasy skin.
-
Neck and skin folds
Warm, moist creases at the neck, armpits and groin can develop a similar shiny, scaly rash.
-
Nappy area
A well-demarcated rash in the nappy area may overlap with cradle cap - often called napkin seborrhoeic dermatitis.
-
Baby is otherwise well
Normal feeding, normal weight gain and a settled baby are reassuring features and part of the diagnosis.
-
Red flag - severe or persistent
Widespread, weeping, bleeding or refractory rash, or a baby who is unwell or failing to thrive, needs medical review.
Treatment
How cradle cap is treated in the UK.
Reassurance and gentle care first - antifungal shampoo or a short course of mild steroid only when the rash is persistent or inflamed.
-
Reassurance and expectant care
For most babies the condition is benign and settles by 12 months. Parents need to hear this clearly and often.
-
Gentle daily hygiene
Regular washing with a mild baby shampoo (for example Baby Aveeno, Baby Dove or Cetaphil Baby) and a soft brush to lift scales.
-
Emollient soak
Apply a bland emollient (petroleum jelly, Vaseline, Cetraben or coconut oil), leave for 15 to 30 minutes, then gently wash off.
-
Sunflower oil preference
Where an oil is used, sunflower oil is often preferred to olive oil, which may weaken the skin barrier in atopy-prone infants.
-
Over-the-counter products
Named products such as Dentinox, Cradocare and Neutrogena T/Gel Baby can help for stubborn scale - follow age guidance.
-
Topical antifungal
Ketoconazole 2% shampoo or clotrimazole/miconazole cream for extensive or persistent disease, usually on a clinician’s advice.
-
Short-course mild steroid
Hydrocortisone 1% for 1 to 2 weeks on inflamed areas of face or folds, prescribed and reviewed by a clinician.
-
Specialist dermatology referral
Refractory, widespread, atypical or worrying cases go on to paediatric dermatology for a fuller assessment.

Red flags
When cradle cap needs a closer look.
Most cases are managed at home. These are the situations that are not - and where a clinician or specialist opinion is needed.
-
Widespread or severe rash
Extensive involvement of the trunk, limbs or nappy area, especially if weeping or bleeding, needs medical review.
-
Failure to thrive
Poor weight gain, poor feeding or a generally unwell baby is never explained by cradle cap alone - seek urgent assessment.
-
Persistence beyond infancy
A scaly, refractory rash that does not settle by 12 months, or that keeps returning, deserves specialist input.
-
Suspected tinea capitis
Patchy hair loss, broken hairs or a boggy inflamed area (kerion) point to fungal infection and need scalp brushings.
-
Signs of infection
Increasing redness, warmth, pus, honey-coloured crusting or fever suggests bacterial superinfection and needs review.
-
Severe atopic eczema overlap
A very itchy, unsettled baby with widespread eczema and a strong atopic history may need coordinated dermatology care.
-
Immunodeficiency features
Severe, refractory or recurrent rashes with failure to thrive or repeated infections warrant paediatric immunology input.
-
Suspected Langerhans cell histiocytosis
A persistent, atypical seborrhoeic-looking rash with purpura, ulceration or systemic features is rare but needs biopsy.
-
Suspected scabies
Intensely itchy widespread rash, especially with palm, sole or web-space involvement and affected household contacts.
Living with it
A benign condition, managed gently.
Four things that make the biggest difference day to day - a simple routine, patience with scales, care of the wider skin and knowing when to step up.
A quiet reminder
This is not your fault.
Cradle cap is not caused by anything a parent has done or not done. Most babies grow out of it on their own before their first birthday.
- 01 Routine
Keep the plan simple
Regular gentle washes, an emollient soak once or twice a week and a soft brush is often all that is needed.
- 02 Patience
Do not pick or scrape
Forcing off scales can damage the skin and invite infection. Soften, wash and let flakes come away on their own.
- 03 Skin care
Mind the rest of the skin
Manage any coexisting eczema, nappy rash or thrush at the same time - overlapping problems make each look worse.
- 04 Escalate
Ask if you are worried
If the rash is spreading, inflamed, itchy, weeping or your baby seems unwell, get a clinician to take a look.
Frequently asked
Everything we get asked about cradle cap.
Quick answers on what it is, how to treat it at home and when to see a clinician.
-
What is cradle cap?
Cradle cap is the common name for infantile seborrhoeic dermatitis - a benign, self-limiting inflammatory scalp condition of babies. It shows as greasy yellow-white or brown scales on the scalp, and can also affect the face, eyebrows, ears, neck folds and nappy area. It typically appears from about 2 weeks of age, peaks around 3 months and usually settles by 12 months.
-
Is cradle cap caused by poor hygiene?
No. Cradle cap is not caused by dirt, infrequent washing or anything parents have done. It is thought to be driven by leftover maternal androgens stimulating sebum production, together with overgrowth of Malassezia yeast (a normal skin organism) and a mild inflammatory response. It is also not contagious.
-
How can I tell cradle cap apart from eczema?
Cradle cap is usually painless, non-itchy and confined to greasy, well-defined patches on the scalp and folds, and the baby is otherwise settled. Atopic eczema tends to be red, itchy and unsettled, often affects the face and outer limbs, and is more likely in babies with a family history of eczema, asthma or hay fever. If in doubt, ask a clinician.
-
What is the best first thing to try?
Wash the scalp regularly with a mild baby shampoo and gently loosen scales with a soft brush. For stubborn scale, apply a bland emollient such as petroleum jelly, Vaseline or a plain moisturiser, leave for 15 to 30 minutes to soften the crusts, then wash off gently. Sunflower oil is often preferred to olive oil in babies prone to eczema.
-
When should medical treatment be considered?
If the rash is widespread, persistent, inflamed or bothering the baby, a clinician may recommend a topical antifungal such as ketoconazole 2% shampoo, or a short course of a mild topical steroid such as hydrocortisone 1% for inflamed areas of face and folds. Salicylic-acid keratolytics are sometimes used briefly for very thick crusts.
-
When should I see a doctor about cradle cap?
See a clinician if the rash is spreading, weeping or bleeding, if it is very itchy or looks infected, if your baby is unwell or not gaining weight, or if the problem has not settled by 12 months. Also seek review if you are worried about hair loss, unusual patches or overlap with severe eczema - all of which may need a different diagnosis.
