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.

Perfect for my dry hair I wear this every day with olaplex no.7 the best thing about the serum that is silicone-free
Report this reviewFine
Like another reviewer, I use Olaplex 6 & 7 as well. If you use these products, this is redundant. It's a nice product, not heavy, but if you are using the other Olaplex styling products, this one is just not going to make any difference to the outcome. I cannot use it without Olaplex 6 as my hair is just too unruly and damaged (bleaching/coloring) for this alone. It's nice but likely best suited for those with not overly processed or thick/course hair.
Report this reviewPerfect for my dry hair
Hairs feel incredibly soft and hydrated. And love the smell
Report this reviewIt's great!
It smoothens hair really well from blow-dry freeze. Just make sure to not use too much! A little goes a long way.
Report this reviewI see a difference when using this product
Every time I use this product my hair is more hydrated and smooth without weighting it down. Just bought my second bottle.
Report this reviewGreat but not the best
I enjoyed the product and appreciate that fact that ir provides heat protection but does not contain silicones, however, found that it leaves my hair greasier/more weighted down as compared to a combination of other Olaplex products that I’ve been using (no. 6 and 7).
Report this reviewIt conditions the hair very well without weighing it down
Works very well on wet hair. If you're using it on dry hair, it's best to use it in the evening as it takes a long time to absorb. It conditions the hair very well without weighing it down. I really don't like the smell, but for me it's not that important.
Report this reviewGreat product
I really can’t imagine my hair care routine without this one. It’s working great and I highly recommend itÂ
