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, 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...

2. Air-dry for a soft texture. Blow-dry for a smooth finish. Diffuse for waves or curls.

Great hair serum
It is a very good serum, great quality. Definitely worth the price. Olaplex never disappoints, it is a trust-worthy haircare brand. It makes effective products that actually deliver results in repairing the hair strands.
Report this reviewA win
This serum helps to strengthen my fine, curly hair. I use it in combination with a leave-in conditioner, as it doesn't leave my hair moisturized enough on its own. When I use it, I feel my curls hold their shape longer.
Report this reviewok
It's an okey serum, would be better for curly hair I think It works and says it protects the hair from heat and damage and although I can't tell, i will keep using it.
Report this reviewLove it
This is the first time I buy this product and small amount of it is enough for my long hair. After 1 use, my dry bleached hair felt softer. My curly hair is looking better if I style with this product. Definietly buy it again.
Report this reviewMy favourite Olaplex product
I’ve tried several Olaplex products but this one is my favourite! This serum also doubled as a heat protector and gives my hair a healthy shine. For someone with curly hair it also keeps my curls soft but in place. Love how lightweight it is!
Report this reviewPleasantly surprised
Has a true serum consistency. Very light, but hydrating at the same time. Spreads nicely on the hair and you don’t need a big amount. Smells nice, typical for their products. Leaves the hair feeling soft and shiny, without weighting it down. Definitely has become a favorite leave on product.
Report this reviewNice serum
Been using this for a while now and it tames flyaways for a smoother look when I’m straightening my hair. Sadly the packaging leaks a little bit if it’s not stored upright, overall good product.Â
Report this reviewNot sure

Report this reviewAmazing
