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.
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 might sound 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 most definitely deserves 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.

Not sure
I love everything Olaplex and own all the other products too, so I really wanted to try this. I've used this for the past couple of weeks now and I guess I don't really feel like it's been money well spent. I have bleach damaged hair that's dry, prone to breakage and my ends tangle easily (especially the hair right down the back of my neck if I work up a bit of a sweat) I love the no. 6 and no. 7 after washing and conditioning as they help detangle and make my hair feel so nourished and soft, I thought maybe I could swap them out for this serum but nah. It smells amazing, but I haven't really noticed it does anything special for me. It doesn't help detangle, it doesn't feel nourishing (have started applying 6 and 7 after this now because I couldn't even get through my hair with a brush with just the serum applied) so to me it just feels like a lovely smelling heat protectant. Maybe over time it could make a difference, but I'm not sure I'd be quick to repurchase this. It's a gel like texture and it is very light weight, so if that's something you're looking for (as opposed to the no. 6), then this might be for you.
Report this reviewSilky soft hair
I've wanted to try this brand for so long and decided to buy this serum as my first product. Smells really nice not too strong either. My hair definitely feels a lot silkier from using this. A little goes a long way. The size is better than what I expected money wise
Report this reviewExcellent Serum
Olaplex is a wonderful brand for hair products, and this serum is absolutely wonderful. It leaves hair super soft and yet full of body.
