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, pollutionandheat damage. Phew!

As with all of OLAPLEX's hair heroes, the star ingredient in this weightless, silicone-free serum is bis-aminopropyl diglycol dimaleate. Thatmightsound 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. 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 neutralise free radicals, act as a shield against pollution, guard your hair from breakage and protect against heat styling. Yep, this multitasking serum mostdefinitelydeserves a place in our hair care line up...

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.

The bond building brand that needs almost no introduction, OLAPLEX has been repairing our dry and damaged manes since 2014 (and we're all the better for it, to be quite honest). Joining the ranks (and our hair care collection) 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 the 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 love from OLAPLEX, ensuring it helps to restore hair to its previous glory too.

    Olaplex No.9
    5 out of 5 stars
    Love this brand, love the smell, the results and the feel. I use this in combination with the leave-in no 6. I have curly hair and use this as a first step when I brush my damp hair. It helps with untangling and forming my curls. I follow with the no. 6 to style. Sometimes I finish with Olaplex oil at the ends too. Not sure if that last step adds anything that's a must.

    All Cerave products are great and this one is no exception. A nicely sized tube which stands by my bed as I use this nightly to hydrate my lips.
