Olaplex No. 9 Hair Serum 90ml

Are dry, damaged lengths topping your list of beauty concerns? Meet the No. 9 Bond Protector Nourishing Hair Serum, a protective treatment that repairs your hair while shielding it from free radicals, pollution, and heat damage.

Like all of OLAPLEX’s hair heroes, the key ingredient in this weightless, silicone-free serum is bis-aminopropyl diglycol dimaleate. This bond-building technology restores and repairs chemically treated and heat-damaged hair, leaving it shiny, soft, and easy to style. Used as the first leave-in treatment on clean hair, this serum also prevents future damage. It's packed with antioxidants that neutralize free radicals, act as a barrier against pollution, guard against breakage, and protect from heat styling. This multitasking serum definitely deserves a spot in your hair care routine.
