Thinning hair needs more than a gentle cleanse. It needs a system. The SATARA OPTI System is a targeted regimen designed for hair that's thinning, shedding, or losing density. This is step one. Inspired by the foundational purity of Satara fabric, this gentle shampoo is powered by Procapil and Capixyl, two patented, plant-based ingredients clinically proven in ingredient studies to support hair growth and reduce hair loss. Collagen adds strength and fullness from root to end. It cleanses thoroughly, but it's working much harder than that under the surface. Is it for you?
