Seborrheic dermatitis
Risk Factors for Seborrheic dermatitis
Seborrheic dermatitis is an itchy flaky scalp condition that closely resembles ordinary "dandruff." Many consider seborrheic dermatitis to be an inflammatory variant of dandruff.
The condition is now understood to be due to a yeast known as Malassezia. Factors such as age, stress, heat, humidity, ultraviolet radiation, neurological disease, depression. HIV/AIDS, Parkinson's disease and medications are all risk factors.
