White Sands Phase 2 Nourishing Shampoo secures hair color and locks in balanced, self-adjusting moisture with a weightless feel before the clear micro-shield seals the hair. Phase 2 is developed for redheads with a pH level 5.6. The higher pH is ideal for redheads, as lower pH levels will squeeze out the color. It contains Heliogenol, an herbal extract that protects tinted hair from color loss by neutralizing the oxidative radicals generated by daily UV exposure while slowing down hair-dye oxidation. It leaves hair shiny and healthy without residue or buildup.
