Take volume to new heights and banish build-up at the root. Use this deep cleansing and clarifying silicone-free shampoo once a week. For those with fine hair, fear not, this shampoo won't weight down your locks. Pro-tip: If root clarifying is needed more than once a week, apply High Amplify Root Up Wash to root area & High Amplify Shampoo from mid shaft to ends. Follow with High Amplify Conditioner or High Amplify Shine Rinse.
