Our HYDRASILK Hydrating Bond System is recommended as a monthly reconstructive treatment to maintain hair wellness. For damaged and highly stressed hair, apply once and re-evaluate and reapply weekly to create a hair wellness plan. Evaluate after each application. *Although monthly treatments are recommended for natural, low stressed exposure to achieve Hair Wellness, if the conditions and resulting stressor are evident, prebook for two additional treatments within the next six weeks and reevaluate condition after each application.
