For the first time, L'Oréal Paris Laboratories have combined 3 Refined Clays to create its first re-balancing range revealing perfectly balanced, beautiful hair, a breakthrough in hair care that understands your unique needs. The Science of Oily Roots and Dry Ends. Oil produced from the scalp can build up causing the roots to become visibly greasy, weighing down the hair. Over-washing to combat this problem can strip the fiber leaving it dry. This results in a vicious cycle of washing. What if you could have hair that was cared for at both ends? The ELVIVE Extraordinary Clay Shampoo gently cleanses excess sebum from the scalp, soothing your scalp and preventing excess oil from building up. However, the shampoo does not dry out your hair - it moisturises your strands right down to the tips. The clarifying sham!
