Seborrheic eczema

What is seborrheic eczema?

Seborrheic dermatitis is a common rash in children, particularly during infancy and adolescence.

This scaly and crusty rash develops on parts of the body where there are lots of sebaceous (oil) glands. These glands are responsible for producing an oily substance that moisturizes and protects the skin.

In infants, the rash commonly occurs on the scalp and is called "cradle cap".

The cause of seborrheic dermatitis is unknown, but there are theories that it is caused by hormones, or a lack of balance between fatty acid and sweat production in the skin.

Treatment / What you should do

Seborrheic eczema rarely needs treatment or the care of a doctor.

In babies with cradle cap, the scales usually can be removed.

First rub baby oil into the scalp.

Wait 10 to 15 minutes and then loosen the scales with a fine-toothed baby comb or a soft brush.

Finally, wash the baby's hair with a mild baby shampoo.

You may need to do this several times before the cradle cap goes away. If the baby is over six months old, you can use a mild anti-dandruff shampoo to help remove the scales, but be careful not to get this shampoo into the baby's eyes. If the cradle cap does not disappear after 2 weeks of treatment, as recommended above, or if you think the rash has become infected, you should contact a doctor.

In older children and adolescents, a mild steroid cream (for example, hydrocortisone) may help to decrease inflammation and skin irritation. Do not use steroids on the face without first talking with a doctor.
