The quickest tell: does it itch?
Cradle cap usually doesn't itch; eczema does. That single difference is the biggest clue. Cradle cap is greasy, yellowish, and your baby seems untroubled by it. Scalp eczema is dry, red/inflamed, and clearly bothers the baby — itch, fussiness, scratching.
Cradle cap (infant seborrheic dermatitis)
- Looks like: yellow or brownish, greasy, scaly patches or crusts on the scalp, sometimes with a little redness. Can extend to eyebrows, behind the ears.
- Feels like: generally not itchy, doesn't seem to bother the baby.
- Timeline: very common in the early months and usually clears on its own by around 12 months.
- Care: often needs little. Gently massaging in a bit of baby oil to loosen scales before a gentle shampoo can help; don't pick at it. It's harmless.
Scalp eczema (atopic dermatitis)
- Looks like: dry, red, flaky, inflamed patches — and often eczema elsewhere too (cheeks, body).
- Feels like: itchy — the baby may rub their head, and it disrupts sleep.
- Timeline: a chronic condition that comes and goes, not a phase that simply passes.
- Care: the usual eczema toolkit — gentle cleansing, moisturizing, and any treatment your doctor prescribes (see baby eczema basics).
When they overlap — and when to check
Real life is messier than a chart: a baby can have both, and sometimes even a doctor takes a proper look to be sure. See your pediatrician if you're unsure, if the patch is clearly itchy or inflamed, if it's spreading, weeping, or looks infected, or if plain cradle-cap measures aren't helping. Getting the right label matters, because the two are handled differently — cradle cap mostly needs patience, eczema needs ongoing care.
