Seborrheic dermatitis is a common condition that makes the skin look greasy, scaly and flaky. It usually affects the scalp. In adolescents and adults, seborrheic dermatitis is commonly mistaken for “dandruff.”
In babies, it is known as “cradle cap.” Seborrheic dermatitis can also affect the skin on other parts of the body, such as the face and chest.
The condition seems to be related to a yeast proliferation on the scalp/skin, called Malassezia Globosa. This organism is normally present on the skin in small numbers, but sometimes its numbers increase, resulting in skin problems.
The main treatment for this condition is a medicated shampoo; used daily it will keep the yeast level down and allow the skin to heal.
If the shampoo alone doesn’t help, your doctor might want you to use a prescription steroid lotion once or twice daily, in addition to the shampoo.
