- Daily sulfate-free shampoo removes excess oil that weighs down hair. Free of sulfates, parabens, gluten & sodium chloride. All types of hair looking to build body, volume, and fullness. Increases the diameter of each hair fiver from within, so hair becomes thicker. Contains Organic Bamboo Extract. Bamboo is the world’s richest resource of natural silica – a lightweight mineral vital to creating volume in hair. The Organic Bamboo works from inside the hair fiber by utilizing Nano Science 10² to deliver Bamboo’s abundant silica deep into the cortex. This lightweight silica bonds to the hair’s cortical wall, boosting rigidity and volume. The result is noticeably thicker, fuller hair. Apply to damp hair, lather and rinse. Follow with Healing Volume Thickening Conditioner.
