Wet hair completely to activate a rich, luxurious lather from the highly concentrated Moroccanoil® Clarifying Shampoo. To completely remove buildup, continue to add water while gently massaging the shampoo throughout hair and scalp. Rinse thoroughly until water runs clear. Repeat if needed. Follow with a Moroccanoil conditioner or mask. This clarifying shampoo may be used twice a month; or up to once or twice weekly for those who use a lot of hair products, swim regularly or have hard water.
