Seborrheic dermatitis is a chronic skin condition that causes a scaly, itchy rash. It can appear as a mild, white scaling or a yellowish greasy or reddish scaly rash. Most commonly affected areas are along the hairline, in and behind the ears, and on the eyebrows, around the nose, and chest.

Dandruff is a type of seborrheic dermatitis. It is the scaling of the skin on the scalp. It can be dry or oily and sometimes itchy.

Seborrheic dermatitis involves swelling and redness of the underlying skin (inflammation), while dandruff is just a mild, white scaling of the scalp (no inflammation).

Treatments for seborrheic dermatitis are usually applied directly to the skin in the form of shampoo or lotion. Treatment depends on the severity of your condition and your symptoms. Treatment can take several weeks or months and may need to be repeated if the condition recurs.

A wide variety of treatments are used for seborrheic dermatitis. These include:

* Prescription or over-the-counter shampoos containing one or more of the following ingredients:
o Pyrithione zinc
o Hydrocortisone or other cortisone (steroid) preparations
