Not great
Very disappointed with this product. Left a coating on my hair and just didn’t deliver the way it promised

Mixed feelings about this product
What is really amazing about this product is that it de-tangles your hair without conditioner. I usually always use conditioner as I cannot comb my hair otherwise. With this product indeed even without conditioner after the 4 minutes waiting time my hair was really smooth and easy to comb through. However, I ma not sure that it really did anything to repair my broken hair. My hair was really broken after bleaching and the overall condition of my hair did not change even after several applications. I finally cut my hair...and now it looks healthy.

Did nothing
I was so excited to try this product as it was all over tiktok. I used it as recommended after showering but it did absolutely nothing. I even tried their detox shampoo, but it also changed nothing. My hair still looks dry frizzy. Feels like a waste of money.

Made my hair dry and brittle
I've been using K18 on and off for almost a year now. I had really high hopes and made sure I followed the instructions every single time and also used detox shampoo. Whilst my hair usually did feel "stronger" after washing, it was even more dry and felt more brittle/ straw like, too. Despite using a really moisturising leave in conditioner. I have highlighted, very long hair and also blow-dry my hair so I thought this would help but I feel like it doesn't do too much.

Useless 👎
Dry and split ends after the very first use. Olaplex n3helped to restore the hair after K18.

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 sadlyÂ

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 HGÂ

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.
