Seborrhoeic dermatitis, sometimes inaccurately referred to as seborrhoea, is a long-term skin disorder.[4] Symptoms include red, scaly, greasy, itchy, and inflamed skin.[2][3] Areas of the skin rich in oil-producing glands are often affected including the scalp, face, and chest.[4] It can result in social or self-esteem problems.[4] In babies, when the scalp is primarily involved, it is called cradle cap.[2] Dandruff is a milder form of the condition without inflammation.[6]

The cause is unclear but believed to involve a number of genetic and environmental factors.[2][4] Risk factors include poor immune function, Parkinson's disease, and alcoholic pancreatitis.[4][6] The condition may worsen with stress or during the winter.[4] The Malassezia yeast is believed to play a role.[6] It is not a result of poor hygiene.[7] Diagnosis is typically based on the symptoms.[4] The condition is not contagious.[8]

The typical treatment is antifungal cream and anti-inflammatory agents.[3] Specifically, ketoconazole or ciclopirox are effective.[9] It is unclear if other antifungals, such as miconazole, are equally effective as they have been poorly studied.[9] Other options may include salicylic acid, coal tar, benzoyl peroxide, and phototherapy.[3]

The condition is most common in infants within the first 3 months or in adults aged 30 to 70 years.[2] In adults between 1% and 10% of people are affected.[4] Males are more often affected than females.[4] Up to 70% of babies may be affected at some point in time.[5]
