Cradle Cap (Infant Seborrhoeic Dermatitis) — What to Do at Home

Cradle cap is the infant form of seborrhoeic dermatitis. It usually appears as thick yellow or white scale on the scalp in the first months of life. It can look dramatic, but it is usually harmless, not contagious, and not due to poor hygiene. Most babies are not bothered by it, and it often improves over weeks to a few months with gentle care. ^(1–4)

What is cradle cap?

Cradle cap is a common, non-contagious scaling condition in babies. It is related to seborrhoeic dermatitis and tends to affect areas with more oil glands. You will usually see it on the scalp, and sometimes around the eyebrows, behind the ears, or in skin folds. ^(1–4)

It is not caused by poor hygiene. In most infants it is mild, settles gradually, and does not cause long-term problems. Most babies are clear by 6 to 12 months of age. ^(1–4)

What it looks like (and where it appears)

Typical features

• thick yellow, white or tan scale on the scalp
• scale may look greasy or “stuck on”
• mild redness underneath can occur
• usually not itchy and baby is generally well ^(1–4)

Common areas

• scalp
• eyebrows and forehead sometimes
• behind the ears
• occasionally chest, armpits, groin folds ^(1–4)

The 7 to 14 day home protocol

A gentle plan that works for most families.

Step 1 — Soften the scale (10 to 30 minutes)

Before a bath or wash, apply a small amount of a bland oil or emollient to the scalp to soften scale. Options:

• mineral oil or paraffin-based baby oil
• a gentle infant-suitable emollient

Leave it in place for 10 to 30 minutes. ^(1–4)

Step 2 — Lift gently (no picking)

Use a soft baby brush or soft cloth to gently loosen scale. The aim is gradual removal over days, not all at once. ^(1–4)

Step 3 — Wash the scalp

Wash with a gentle baby shampoo, then rinse well.

Repeat this routine daily or every second day for 1 to 2 weeks. ^(1–4)

Step 4 — Maintenance once improved

Once cradle cap is mostly clear, reduce to:

• softening plus gentle brush 1 to 2 times per week, or
• wash normally and repeat only if scale returns ^(1–4)

What to expect: scale usually thins and lifts progressively over several washes.

If cradle cap is stubborn

If scale is thick and returning quickly, a doctor may recommend a short course of a targeted treatment — for example a mild antifungal or a very mild anti-inflammatory — particularly if there is significant redness or inflammation. This is generally reserved for more persistent cases or where the diagnosis overlaps with eczema or contact dermatitis. ^(1–4)

What to avoid

• do not pick, scratch or scrape with fingernails or combs — increases irritation and infection risk ^(1–4)
• avoid fragranced oils, strongly scented natural products, or essential oils on the scalp
• avoid harsh shampoos or adult anti-dandruff shampoos unless specifically directed for your baby

If the rash spreads beyond the scalp

Sometimes infants also get seborrhoeic dermatitis in:

• eyebrows and forehead
• behind ears
• skin folds — neck, armpits, groin ^(1–4)

In these areas, the approach is still gentle:

• cleanse with lukewarm water
• use a simple, fragrance-free moisturiser or emollient
• avoid over-washing or scrubbing

If the folds are very red, weepy or sore, it may be eczema, irritation, yeast overgrowth or infection — and it is worth getting reviewed. ^(1–4)

When to see a doctor

Book a review if:

• the scalp is very red, swollen, weeping, crusted, bleeding or has a bad smell
• baby seems uncomfortable, itchy or unsettled from the rash
• the rash is spreading widely beyond the scalp
• there are signs of infection — oozing, honey-coloured crusts, increasing tenderness
• it has not improved after 2 to 4 weeks of gentle home care
• you are unsure whether it is cradle cap versus eczema or another dermatitis ^(1–4)

Where this fits

Adjacent reads in the seborrhoeic dermatitis library:

• Daily scalp routine for dandruff — adult scalp protocol
• Facial seborrhoeic dermatitis plan — adult facial protocol
• Prescription treatments — when OTC is not enough
• Facial flaking guide — seb derm vs rosacea vs peri-orificial vs psoriasis

If cradle cap is persistent, inflamed, spreading beyond the scalp, or you are not sure what you are dealing with, the appointment confirms the diagnosis and guides you to a safe plan — with targeted treatment only if genuinely needed.
