The severity of
seborrheic dermatitis can be lessened by controlling the risk factors
and by proper skin care. Over-the-counter dandruff or medicated shampoos is usually indicated for the flaking. However, shampoos or lotions containing selenium, ketoconazole, or corticosteroids may be prescribed for severe cases. To apply shampoos, part the hair into small sections, apply to a small area at a time, and massage into the skin. Support groups, local or on-line, may also help.
