Repair damaged hair from the inside out with Bond Serum, powered by the HAIRSTORY exclusive ProTarget Technology™.

This lightweight leave-in treatment delivers more intense and prolonged recovery benefits than other hair repair treatments plus heat protection up to 450°F.

Double repair ProTarget Technology™ is uniquely formulated with liposomes that zero in on compromised areas of the hair. 

• Within the fiber, a clinically proven complex with itaconic acid and arginine restores disulfide bonds that have been damaged by chemical treatments like dyes, bleach and relaxers.
• On the outer cuticle, nourishing ingredients including panthenol and ceramide NP replenish moisture to heal frizz and prevent split ends and breakage.

Hair is stronger, smoother, softer and shinier—for longer.
