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. That might sound a bit science 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. Slotting into your routine as the first leave-in treatment on clean tresses, this serum protects from future damage too, as it’s packed with antioxidants to neutralize free radicals, act as a shield against pollution, and guard your hair against breakage and protect against heat styling. Yep, this multitasking serum most definitely deserves a place in our hair care lineup.How to Use:1. Apply a small amount to damp, towel-dried hair working upward from ends to roots. Use more as needed for longer, thicker hair.2. Air-dry for a soft texture. Blow-dry for a smooth finish. Diffuse for waves or curls.3. Apply sparingly to dry hair for frizz and static control and added shine.Joining the ranks is the brand’s very first leave-in serum, the ever-so-protective No. 9 Bond Protector Nourishing Hair Serum. Pollution can damage our hair on a daily (think: dull lengths, breakage, frizz — the list is endless), but just a couple of pumps of this creates a protective layer over strands to stop pollution in its tracks. Oh, and of course, it’s also supercharged with the same bond-repairing technology you know and loves from OLAPLEX, ensuring it helps to restore hair to its previous glory too.
