I'm impressed and love it!

Bought the smallest size at my hairdressers, and was impressed. Now, I just bought the 50 ml size and I swear by it. I have fine and long hair, so I am always looking for volume, and this improves my hair, it really does. My hair is shinier, it has more volume, if the volume is thanks to K18 I don’t know but the styling gets better… The hair looks healthy and shiny. I’ve been loving the Olaplex nr 3 and 6 but this is better. And I love that I don’t have to rinse my hair, just wait 4 minutes and style as usual. I will continue to repurchase.

No noticeable difference

Did nothing to my hair. I skipped the conditioner and was wondering how this product would cope with my curly dry tinted hair. It didn’t. So expensive and a waste for me sadly

The best

My 57 year old, menapausal, highlighted, dry,   frizzy and unruly hair has now reverted back to the hair I had donkeysyears ago, results were noticeable after the first use and my hair’s  now sleek, smooth, glossy, hydrated and totally manageable. I do use a couple of other products , Colour Wow Dream Coat and CHARLOTTE MENSAH hair oil,  I’m now back in love with my hair and This product, for me, is now a HG

NOT universally suitable

Wish I had checked the ingredients before purchasing. This is basically a protein leave in conditioner (ingredients state Wheat Protein). Using protein when your hair doesn't need it will cause it to be dry, brittle, dull and straw like. This is exactly what happened to mine. If your hair is protein deficient it may help you but please do a quick Google search to check if your hair needs it before spending the hefty amount on this product. You may just need a deep moisture mask.

Beautiful shiny hair

Bit suprised by some reviews here. I have long, fine, balayage hair, which was badly damaged by overly strong bleach. I bought this product beginning of July and went through the course of 6 treatments within a week (I usually wash my hair every 2-3 days but heatwave happened to coincide). I apply 3-4 pumps, starting with the ends and working my way up. I leave it for a few minutes, comb through, and let dry naturally. I now use it every 3 washes and use my regular conditioner in between (label.m, oat and honey). My hair is soft like baby hair. The shine is incredible. The frizz is gone. The hair does not tangle in between washes either, which is the first for me. I love this product and definitely repurchasing.

Nothing special

Apart from being excruciatingly expensive for a tiny amount, this did nothing for my hair at all. I have thick, curly hair that is prone to breakage. Its not strong enough as a conditioner alone for my hair type, and made no visible difference to breakage. I'll stick with Olaplex.

Hate to say it but…

Totally didn’t think I’d love this product but sadly I do. (Sadly, purely just down to the price!) I have long, naturally curly, frizz prone hair so I need more of this than the recommended x2 pumps. My hair didn’t feel a whole lot different once blow dried but after straightening I was blown away by how nourished my hair felt having not used conditioner. Three days in and my hair still feels AMAZING. Total convert!

Easy to use

I am a fan of olaplex but thought I would give this a try as it seemed easier to use. My hair is quite fine and it certainly was more manageable but if I use it again I will only use on the ends.

Top notch!

This stuff is brilliant. I’ve tried so many serums and intensive conditioners that work ok but not brilliantly - this really does the job it says it does.  You don’t need that much of it, which is good because it is ridiculously expensive for the amount you get, but honestly my hair is so swishy and silky afterwards. I love it.
