Wella SP Color Save Infusion, in combination with Wella SP Color Save Mask, protects hair from fading for optimal color protection, as well as smooth and shiny hair. Application of Wella SP Color Save Infusion: Use a Save Infusion ampoule in combination with the SP Color Save Mask. Distribute the cure in the lengths and ends of your hair and leave on for 5 - 10 minutes. After the exposure phase, rinse out the intensive treatment thoroughly. Pro Tip: The Color Save Infusion as a treatment should not be used when working with the Color Save line, but as an additive for another Wella SP line mask. This gives the hair additional intensive color protection.
