Seborrheic Dermatitis Triggers
The cause of seborrheic dermatitis is unclear. A common species of yeast normally found in healthy hair follicles has been proposed as one possible cause. A high-fat diet and alcohol ingestion are also thought to play some role. Other possible triggers include stress, fatigue, extreme weather, oily skin, obesity, AIDS, Parkinson’s disease and other disorders.
What to Expect
The symptoms of seborrheic dermatitis, such as itching and scaliness, reduce gradually under treatment. Your dermatologist may tell you to use a medicated lotion or shampoo every other day until you get relief, and then twice weekly to control the symptoms. See your dermatologist if you think you may have seborrheic dermatitis — only a doctor can make a complete diagnosis.
