If you use hair products such as clay's then this is a must. I use it once every two weeks instead of the recommended once every week and it really does do a great job at cleaning out all the gunk that is left over that normal shampoo's do not remove. It a must have for any avid hair stylist to keep your hair from becoming to heavy and not getting the volume you're looking for.
positive
