More Info
Your routine-boosting 2nd step—after shampoo + before conditioner or rinse-out mask:
Boosters perform best on freshly cleaned hair to ensure the active ingredients can penetrate the hair shaft. To seal in the treatment + deliver optimal results, layer your conditioner or rinse-out mask of choice directly on top of the Booster. Learn more about how Boosters work.
Elevate the co-wash experience with Strength Booster:
Reinvigorate your co-washing experience with Strength Booster on no-shampoo days. Simply apply the Booster + then layer your conditioner of choice on top. Read more about co-washing here.
How to Use
After cleansing with your shampoo of choice, gently remove excess water. Generously spray Strength Booster from mid-shaft to ends; don’t rinse out! Layer your choice of conditioner or rinse-out mask over top. Comb throughout. Let activate for a minimum of 30 seconds (longer if needed) + then rinse thoroughly.
