Rusk introduces an innovative solution to protect hair and overcome daily assaults; deepshine. These unique formulas actually saturate hair with deep penetrating and revitalizing nutrients. The benefits of Thalassotherapy or "sea therapy" have been recognized for centuries. Now Rusk defines this ancient practice by harnessing the latest marine technology. Deepshine infuses hair with highly concentrated and moisturizing bio-marine extracts, natural moisture-rich lipids, protective UVA/UVB absorbers and strengthening vegetable proteins, the essential ingredients for achieving and maintaining healthy, shiny hair.
