Go light and bright, bold and beautiful–all without surrendering the integrity of your client’s hair. With the introduction of Bond Fusion, Keune Haircosmetics begins a completely new chapter in healthy hair. This revolutionary new system is a premium bond-boosting treatment compatible with any salon chemical service and all hair types.


Several salon services like hair color and texturizing treatments break down disulfide bonds, which are essential for resilient, healthy hair. Bond Fusion’s three-phase system repairs and rebuilds broken bonds, and even creates new ones, as it continuously treats and conditions chemically damaged hair to keep it strong and shiny. In addition, Bond Fusion helps to preserve the hair during perming and straightening services, and can even be used on its own as a damage-repairing treatment. As a result, stylists can now achieve maximum bond restoration—with multiple benefits and no reformulating or extra processing time. 


Working with Bond Fusion is easy. There are three steps. 

Phase 1: Build. Keune Bond Builder repairs broken bonds, creates new bonds and protects the inner structure of the hair with two types of hair-identical proteins. Simply add Bond Builder to your color or lifting mixture as directed.

Phase 2: Enhance. Keune Bond Enhancer is a deeply nourishing and restorative treatment that strengthens and seals the bonds in each individual strand to ensure that hair stays in the best condition for as long as possible. After rinsing the color, apply Bond Enhancer from roots to end, leave in for at least 5 minutes, then rinse thoroughly.

Phase 3: Recharge. This nourishing maintenance product for use at home prolongs the results of the Bond Fusion salon treatment.



Hair treated with Bond Fusion has five times more long-lasting conditioning. The conditioning effects resulting from just one Bond Fusion treatment indicates that the hair’s combability, softness and smoothness remain comparable after five shampoos. 

After a lightening process and 1,000 comb strokes, hair treated with Bond Fusion experiences 43-percent less hair breakage and is twice as easy to comb through as lightened hair not treated with the Bond Fusion system. The hair looks healthy, soft and conditioned.

Each claim in support of Bond Fusion is based on the average results of three independent lab tests, performed following standardized, reproducible and documented procedures, developed by Keune’s Research & Innovation department.
