Iles FormulaIles Formula Haute Performance Shampoo

Some shampoos can clean hair a little too wellcausing color to fade and moisture to be sucked away. But this gentle formula, designed by celebrity hairstylist Wendy Iles, cleanses grime and buildup from the roots and instantly transforms all hair types into spun silk perfection. And dont worry: it may be free of sulfates (and therefore safe for color-treated hair), but unlike some sulfate-free shampoos, it foams to a seriously rich lather.
