Hydrate Me Rinse, Kevin Murphy’s Moisture Delivery System, is a smoothing treatment for dry or dehydrated hair. It floods even the driest strands with moisture, helping to restore shine and strengthen the hair fibers. After use, your hair will feel silky and gleam with a radiant luster. For best results, apply the conditioner to freshly washed hair, leave on for one minute, and rinse thoroughly with water.
