Thanks for the query.
Most of the times these preparation is in the form of shampoos. You should apply atleast twice a week, the frequency may be different depending on severity of the skin condition. After application,keep on the scalp for atleast five minutes. this contact time is needed for the medicine the shampoos to act. Rinse the scalp thereafter.
Hope it helps.
