5. How does it work & how long does the custom hair treatment take?

Before beginning your treatment, your stylist will diagnose your hair. Depending on what your hair needs most, they will select a Concentré and Booster to combine and spray onto the hair at the back bar. Within 5-minutes, your tailor-made treatment will be complete and you’ll be flaunting lush, re-energized hair all day!

6. Is Fusio-Dose the same as a hair mask?
