Vert Veil is formulated with a balanced blend of ingredients found in iogus treatment. It replenishes the beautiful hair components that are washed away with daily shampoo, providing moisture and maximizing the "uniquely smooth texture, manageability, and shine" of the iogus treatment. This is a 1000g professional-use product (equivalent to 20 bottles of the 50g product; the ingredients are exactly the same as the 50g product). It's a much better value than the 50g product.
