Those yellowish, slightly greasy scales on a baby's head have a name: cradle cap. It looks more dramatic than it actually is — it almost never hurts or itches, and in most cases it goes away on its own over time.
What it is
It's a form of seborrheic dermatitis very common in the first months. The exact cause isn't fully clear, but it's linked to excess oil production in the skin, likely triggered by maternal hormones still circulating in the baby after birth. It has nothing to do with hygiene or anything you did wrong.
What it looks like
- Yellow or brown scales, sometimes thick and crusty-looking, on the scalp.
- The skin underneath can look a bit red.
- It can also show up on eyebrows, behind the ears, or in neck and armpit folds.
How to treat it at home
- Gentle oil massage (mineral or baby oil) before bath time, to soften the scales.
- Soft-bristle brush after the bath, to gently comb out what's already loosened.
- Mild baby shampoo, with regular scalp washing.
- Don't scratch or force it off — it'll clear up on its own with consistent care like this.
When to call the pediatrician
- It spreads a lot across the body, beyond the typical areas.
- It looks very red or inflamed, or shows signs of infection.
- It doesn't improve after several months of consistent care.
- The baby does seem bothered or itchy — that could point to something else, not simple cradle cap.
