In Our Own Words

Seborrheic dermatitis is a dermatological condition that can affect infants or adults. In adults, it causes white or yellow greasy scales to form on the scalp. Sometimes red or greasy patches can be found on the ears and face. In infants, seborrheic dermatitis, known as cradle cap, typically causes crusty yellow or brown scales to form on the scalp and sometimes on the eyelids, nose and groin.

 

The cause is not known, but overgrowth of yeast on the skin may be a trigger. Other conditions, including HIV infection, stroke, head injury, Parkinson's disease and epilepsy, are associated with seborrhea. Special dandruff shampoos and mild baby shampoo can help.
