Seborrheic dermatitis (SD) is a common, chronic condition that produces red, itchy scales in areas of the skin where there are many sebaceous glands, such as the scalp, eyebrows, chest, nose, ears and armpits.
The scaling and flaking of SD is caused by an excessive growth of surface cells. The scales of SD may be powdery and dry, or moist and greasy, and at times they may ooze. If left untreated, the scales may become thick, yellow and greasy and, occasionally, a secondary bacterial infection may occur.
What is the Difference Between SD and Dandruff?
Dandruff causes a dry, powdery white flaking of the scalp, often accompanied by itching. SD is also itchy and flaky, but the scalp is inflamed and red.
SD in Infants
When SD occurs during infancy, it is also called "cradle cap" because it usually occurs around the scalp and ears. Symptoms may also be present in the diaper region or any bent surface areas.
For a complete diagnosis, you should seek the advice of a dermatologist. If you don't have a dermatologist, the DermFinder® directory can locate one near you.
