What causes seborrheic dermatitis?

The cause of seborrheic dermatitis is unknown. It appears to have something to do with an overproduction of oil in the skin. There is also thought to be a link to irritation caused by a type of yeast called malessizia, but this has not been proven.

The exact cause is not known, but studies show that a fungus called malassezia, which causes the skin to over-produce oil, may be to blame. Genetics may also play a role in developing the skin disease. A family history that includes eczema or other skin diseases may make a person more prone to seborrheic dermatitis. But factors beyond family history may also affect the likelihood of developing seborrheic dermatitis, such as stress level, fatigue, dry air or neurological conditions like Parkinson's disease.
