DOSAGE AND ADMINISTRATION
SHAKE WELL BEFORE USING
For seborrheic dermatitis and dandruff
Wet skin and apply to areas to be cleansed. Massage gently into the skin working into a full lather. Rinse thoroughly and pat dry. Generally two applications each week for two weeks will control symptoms. Subsequently, shampoo may be used less frequently, or as directed by a physician. It should not be applied more frequently than necessary to maintain control.
