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 fullness for thin, fragile, color-treated hair. The hair does not become darker or dull and never feels stiff or sticky: it remains flexible, soft, and voluminous. A UV filter helps maintain color and protects the hair. It can be used on wet or dry hair. Application: Spray onto damp or dry hair, focusing the application on the hair roots. Style and direct heat from the blow dryer towards the hair roots.
