Founded in 2014 by Dean Christal, OLAPLEX has changed the landscape of the hair care industry. After employing two chemists to find a chemical that wouldn't damage dyed tresses, the team formulated the brand's proprietary, patented bond building technology. Joining the ranks (and our hair care collection) is the No.9 Bond Protector Nourishing Hair Serum (90ml) which creates a protective layer over strands to stop pollution and environmental aggressors in their tracks.
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 (90ml), a nourishing treatment that protects from free radicals, pollution and heat damage.
Restoring chemical-treated, heat-ridden hair and leaving it full of shine, soft to the touch and easier to style, you'll be reaching for this multitasking staple time and time again. Protecting from future damage, it's packed with antioxidants to neutralise free radicals, shield against pollution, guard your hair from breakage and defend against heat styling. Yep, this really is what hair care dreams are made of...

Amazing products
Ive been using the olaplex range since having hair extensions removed which ruined my hair,my hairdresser recommended me these products and although reluctant first of all as quite pricy it is well worth it,my hair has never been in the best of condition, dry and breaks easily, this range has really left my hair in the best condition its ever been in and a little does go along way, throughly recommend

This sets the bar!
A small tube of this was included in one of the hair kits, and having finally got round to trying it, I'm completely blown away by how effective it is - quite simply, on dry hair, its the best serum for smoothing, eradicating frizz and imparting a super-sleek, silky shine. A tiny amount is all that's required and hair never looks lank, even after top-ups. I have the oil too (a little greasy so use in the evening as an overnight mask) but this is significantly better & I won't leave the house without it. I've since bought the full-size however it would be helpful if the 20 ml tubes were sold separately to throw into handbags.

A nice treat
Again with the products in this range it's something I reach for as a home spa style treat - not an every day product for me - mainly due to the price point. I do like the smell and texture of this serum but I do feel like I need to use a lot of it to actually see visible results. Over time using the range it's definitely made a difference to my hair condition; but I think that's more the n03 repair & shampoo/conditioner.

Good, not great
It’s not amazing like some of the other Olaplex products. It’s good. Weightless, which works well with my thin hair, but I use other serums with it. So not good enough to be used on It’s own

Game Changing
I have tried most of the Olaplex range and this is one of my favourite products. I notice a genuine difference if I do not use it. A little goes a long way and I have very thick shoulder length hair. It delivers on all of its claims. Highly recommend.

Olaplex
Another great effective product from Olaplex. Does not disappoint, easy to use , no wait time as a leave in product. I have highlighted hair that a fairly fine and wanted a product that I could air dry with and this was excellent. No more frizz. Would definitely buy again .

Nice addition
I have been using olaplex products for a couple of years but this has been a really nice addition and smells amazing. The numbers are a bit confusing but I find this works best if I use it on wet hair before 6 and 7

Good product
I bought this to try because it has heat protection, and I’m really pleased with the results. A little does a long way, and it makes my hair smooth and shiny. Can leave my hair a little static sometimes, but overall it’s very good.

Great multi-tasking hair serum
A recent purchase along with Olapex No.7 Bonding Oil. Beautiful light texture, doesn't weigh my fine hair down, however warning to first-time users: alittle goes a very long way!! Great results whether I'm air-drying my locks or applying heat.
