Cradle cap (seborrheic dermatitis) is a type of eczema, thought to be caused by overactive oil glands on the scalp and face. The condition can sometimes also affect necks, ears and even armpits.
What does it look like?
Yellowy/brown greasy flaky scales and sometimes the skin around can look a little red. It usually appears in the first few months and will normally clear up by their first birthday.
The good news is that there is no evidence that it causes children discomfort.
How to treat it
Most cases of cradle cap will clear up on their own but you can gently massage the scalp using circular movements with a baby brush and then apply a natural oil such as olive oil into their scalp to help or there are several special shampoos that you can buy in pharmacies that may also help.
NEVER PICK AT CRADLE CAP as this can cause infection, leave it to fall off naturally.
