Seborrheic dermatitis is an extremely common medical problem which is usually isolated and does not indicate in any way a serious underlying medical problem. The condition usually shows up as scaly,flaky areas of redness and irritation in parts of the skin that are rich in oil glands, especially the scalp, hairline, forehead, and around the nose.
There are numerous individual factors that contribute to a flare of seborrheic dermatitis, including a person's particular skin sensitivity and stress level. Probably most flares of seborrheic dermatitis, however, are related to an allergic reaction to a type of yeast that normal lives on the skin called Malassezia.
Treatment for seborrheic dermatitis includes good skin hygiene and use of a dandruff-type shampoo for areas in the scalp and hairline. Additionally, over the counter antifungal medications and steroid creams may be of benefit. If these medications do not work for you, then it is time to talk with your primary care doctor
or your dermatologist
. Prescription strengths of selenium sulfide (the active ingredient in most dandruff shampoos) are available, as are stronger antifungal and steroid creams. Occasionally, in very stubborn cases, your doctor may prescribe oral steroid medications, but this is usually not necessary.
