Color Wow Raise The Root Thicken + Lift Spray is the solution for flat hair. Typical sprays that target the roots use resins to harden, which can make colored hair dangerously stiff, brittle, and prone to breakage. These resins can alter the color. This game-changing spray provides a significant, long-lasting lift and volume for thin, fragile, color-treated hair. The hair does not darken or become dull and never feels stiff or sticky: it remains flexible, soft, and voluminous. A UV filter helps with color retention and protects the hair. It can be used on wet or dry hair. Application: Spray onto damp or dry hair, focusing on the roots. Style and concentrate the heat on the roots while blow-drying.
