L21.1: Seborrhoeic infantile dermatitis
The areas of skin that are usually affected are those that produce a lot of sebum and are often hairy.
You have scaly, crusted skin there. It is usually the scalp and face that are inflamed.
The rash often occurs in babies. After the birth, babies still have their mother’s hormones in their blood. These hormones cause the sebaceous glands to produce a lot of sebum. In babies, the rash usually fades away within their first 3 months. Often, the skin does not itch at all, or only a little.
