Used together as part of our STIMULATE regimen, the combination of STIMULATE.ME WASH and RINSE delivers a breakthrough combination of ingredients that awaken and clarify the hair and scalp, preparing both to receive the benefits of THICK.AGAIN. Thinning hair, hair loss and brittle, weak hair are the biggest complaints we hear from our male clients, so we developed this high-tech trio to help thicken the hair’s appearance.
