    I was in two minds about buying k18 but im so pleased I did!
    My hair instantly regained it's CURL after the first treatment. My ends don't look fried anymore. I've now done 2 treatments so the results are incredible. I don't colour my hair but my hair is dry curly and highly porous.
    K18 has given me the best results of any product ever used.. now i don't have to cut off the damaged ends!
    I used davroe clarifying shampoo before using k18 for great results. I didn't need to use a hair treatment after the 4 minutes you have to leave k18 to soak in.
    I read some reviews that said users needed extra conditioning after applying but i did not.
    Wonderful product, highly recommend!
    Thanks ingrid at hair plus.

    I’ve been using K18 on my bleached, prone to breakage hair, for two years now and it truly does make all the difference even compared to other high end products. Much less breakage at my foil appointments, thicker and healthier hair. This 15ml size is great for when you cant fork out the cost of the full size one, I have shoulder length hair and have gotten 6 uses out of this and still going

    K18 truly does what it claims to do. After applying it you can feel and see it working. When I blow wave and style my hair I find that it looks much better when I've used K18 too. A little bit goes a long way. Leaves hair looking healthy and smooth. I have fairly damaged hair due to bleach/colouring and I suffer from dry, split ends. This product really helps. Highly recommend.

    I have been using K18 for my super fine hair and it works wonders! I put it in with my fingers using them like a comb and putting the product from the ends to just about the top of my scalp. It’s not oily or heavy and it really has conditioned my hair from all the colouring I have done in the past 35 years. This works and I can shampoo then put K18 in and blow dry my hair. Just remember to leave in for 5 minutes to get the full conditioning effect. Anyone with fine hair will have tried lots of conditioning products - but this actually works. My new best product recommendation.

    It's early days with using this product, but I wouldn't say it's lived up to the hype. I have quite badly bleach damaged straw like hair and I'd say it's only been marginally softer and more manageable. I wouldn't buy this product expecting the miracle you might have been promised

    I do not rate this product at all. Used as per instructions and was left with horribly greasy roots and frazzled dry ends. Could not wait to wash it off and get some conditioner on my hair. Glad I did not buy the large size.

  • Not worth the hype or the hefty price tag…

    Posted by Hannah on 27th Apr 2022

    I bought this product after trying it in the salon. Due to not conditioning afterward, and I’m suspecting not enough product, my hair was left feeling really dry and horrible after. I bought it anyway because it was recommended to use four consecutive times to really take affect and I was worried about my hairs health after bleaching. I have thick, wavy, mid length hair, but the small bottle suggested I start with three pumps and go from there (equivalent to one pump in the bigger bottles). Three was nowhere near enough for my hair, so I did three each side. I think I had good coverage without going overboard so I don’t suspect user error - but by the end of the four washes my hair did not feel as promised by the convincing description or the hefty price tag. It was worse off then if I had regularly washed it and it was a painful 4 washes before I was finally able to use shampoo with conditioner as normal. I have reverted to once a week now that my four consecutive washes is over and I still haven’t noticed any changes. I’m not sure if I am actually using it wrong or if this product just doesn’t suit my hair. I’d welcome some guidance, but if I don’t think I’ll be purchasing again unless someone can confirm user error.

    If your blonde or trying to go blonde , buy this immediately ! Amazing product , i use this along side Olaplex 3,4,5 & my hairs the healthiest its ever been despite going from brown to blonde in 6months , iv had zero breakage.

    Posted by Emma J on 17th Apr 2022

    Bought the small size just to try. Am now going to buy full size! I can tell it’s working because combing my hair without using conditioner is getting easier and easier everyday! I have a lot of hair, but it’s fine, so it’s hard to find products that don’t weigh my hair down or make it look greasy.
    Take the plunge - you won’t regret it.
    Better than Olaplex

    This is liquid gold. A hairdresser friend recommended it to me, stressing the importance of only using the prescribed amount. You can tell a difference from the first use, after using a clarifying shampoo, but after wash #4, my extremely processed white-blonde hair feels like it did before colouring it. Worth every cent, and I’ll keep buying it forever!
