Seborrheic dermatitis causes a red rash with yellowish and somewhat "oily" scales. In addition to the scalp, seborrheic dermatitis can occur on the sides of the nose, in and between the eyebrows, and in other oil-rich areas. Seborrheic seb-o-REE-ik dermatitis is a common skin condition that mainly affects your scalp. It causes scaly patches, red skin and stubborn dandruff.

Seborrhoeic dermatitis is a common scaly rash that often affects the face, scalp and chest, but it can affect other areas. There are two types: adult and infantile. This information is for adults with seborrhoeic dermatitis. Infant seborrhoeic dermatitis known as cradle cap differs from the adult form and is discussed in a separate National Eczema Society factsheet, Seborrhoeic dermatitis and cradle cap in infants.
Considered a chronic form of eczema, seborrheic dermatitis appears on the body where there are a lot of oil-producing sebaceous glands like the upper back, nose and scalp. Among adults and teens, the condition is more common in males. In adults, however, seborrheic dermatitis usually follows a pattern of flaring and clearing that can last for years. The Malessezia overgrows and the immune system seems to overreact to it, leading to an inflammatory response that results in skin changes.
