What are the symptoms of seborrhea?

The main feature of seborrhea during childhood is red skin covered with greasy, crusty scales. It’s most common behind the ears, under the arms, in the diaper area, and on the face and neck. In the first month of life it is most common on the scalp, where it is called cradle cap. In teens, the seborrhea may only appear as the dry flakes of dandruff. It may also appear on the eyelids or concentrated in the beard area. Occasionally it shows up in ear canals or in the belly button.
If seborrhea itches at all, the itching is typically mild.

Often seborrhea cannot be prevented. Sometimes gentle skin cleansing and avoiding excess perspiration can reduce or prevent seborrhea.
