Dry, damaged lengths at the top of your beauty bugbear list? Allow us to introduce you to the No. 9 Bond Protector Nourishing Hair Serum, a protective treatment that repairs your mane while protecting it from free radicals, pollution and heat damage. Phew!

As with all of OLAPLEX’s hair heroes, the star ingredient in this weightless, silicone-free serum is bis-aminopropyl diglycol dimaleate. That mightsound a bit science-y but this bond-building technology will restore and repair chemical-treated, heat-ridden hair, leaving it full of shine, soft to the touch and so much easier to style. This serum protects from future damage too, as it’s packed with antioxidants to neutralise free radicals, act as a shield against pollution, guard your hair from breakage and protect against heat styling. Yep, this multitasking serum most definitely deserves a place in our hair care line up…
