Seborrhoeic Dermatitis in Babies: Beyond Cradle Cap | Parenting Hub
When cradle cap spreads to the eyebrows, neck folds and nappy area — that's infant seborrhoeic dermatitis. Here's how to care for it.
When cradle cap turns up in the eyebrows, behind the ears, in skin folds or the nappy area, it's the same condition with a longer name: infant seborrhoeic dermatitis. It's harmless and clears within months.
Where it shows up
Same yellowy greasy scales as cradle cap, but in other oily areas: eyebrows, behind the ears, sides of the nose, neck folds, armpits and (confusingly) the nappy area. Usually appears in the first 3 months and clears by 6–12 months.
Gentle care
- Wash with plain water or a mild non-soap cleanser.
- Massage a small amount of plain emollient or natural oil into scales, leave 15 minutes, then gently brush off and rinse.
- Don't pick — it can damage delicate skin.
- For persistent eyebrow or skin-fold scale: ask your GP about a short course of 1% hydrocortisone or an antifungal cream.
Cradle cap vs. eczema
Cradle cap/seborrhoeic dermatitis isn't usually itchy — babies don't seem bothered. Eczema is itchy, dry and bothersome. If your baby is scratching or unsettled by the rash, get a GP review.
When to seek help
- Weeping, oozing or yellow pus (possible infection)
- Rash spreading rapidly or baby very unsettled
- Not improving by 12 months
Common questions
Is it the same as cradle cap?
Yes — same condition, different body parts. See our cradle cap article for more detail.
Will my baby grow out of it?
Almost always by 12 months. It rarely returns later in childhood.
