Olaplex’s New No. 9 Hair Serum Wants to Protect Your Hair From Pollution


At this point whenever Olaplex launches a new product, it’s pretty much guaranteed to be a gamechanger in our hair routine. That’s why we’re so excited that the brand behind so many of our favorite salon-grade hair treatments has introduced its newest innovation and first leave-in serum to its already impressive product-lineup.

Meet the No.9 Bond Protector Nourishing Hair Serum. Dubbed the “anti-damage hair shield”, this nourishing, silicone-free serum provides protection against free radicals while repairing damage caused by heat and pollution in all hair types. It also promises satin shine, style memory, tangle and static control, and even heat protection up to 450°F.

“It also has a curved retention memory and a body retention memory as you style your hair,” JuE Wong, chief executive officer of Olaplex, told WWD. “We are excited about this No.9 launch because protection is the one thing people are most concerned about besides repairing their hair.”

Similar to Olaplex’s other products, this weightless serum contains their multi-patented bond-building technology that works to reconnect broken bonds in the hair shaft and repair your locks from the inside out. No. 9 is also packed with hydrating ingredients like hyaluronic acid and panthenol that restore moisture to dry, damaged locks. But, the real star of the show is red algae extract, which is a potent antioxidant that seals out and neutralizes unwanted free radicals before they cause static, tangles, and hair breakage.

If you’re wondering how best to incorporate No. 9 into your current styling routine, Olaplex recommends using it as the very first step. You’ll want to apply a small amount to damp hair working upward from ends to root—using more as needed for longer, thicker hair. While you can totally use the No. 9 by itself, you can follow up with No. 6 Bond Smoother for frizz control and/or No. 7 Bonding Oil for added shine. Afterwards, you can style as usual. Olaplex suggests air-drying for a soft texture, blow-drying for a smooth finish, and diffusing for waves or curls.

Ready to try it out for yourself? Olaplex No. 9 Bond Protector Nourishing Hair Serum is available for $28.00 at Olaplex.com or Sephora.
