It is best to prime the pet by bathing/cleansing in DermaPet Conditioning Shampoo. Then rub DERMALLAY Shampoo into skin and/or coat until lightly lathered. Wait 5 to 10 minutes and rinse well. Use as often as necessary or as directed by veterinarian. To help restore natural skin oils and revitalize dry, irritated skin, use DermaPet DermAllay Conditioner after bathing and between baths.
