Phenomanal
I have a full head of bleach and have had for over 15 years. Yeah it’s high maintenance and at the min my hair is tired  dry and dull.After doing much research I came across this little beauty and I have to say I have used it once and Oh My Word! This is amazing my hair felt lies brittle and tangly and absolutely amazing. It blow dried really nice and smooth.  Mentioned to to my hairdresser and she said it’s amazing isn’t it better than olaplex… now that is a big statement but I have to say I agree.  I’m going to use this twice a week as my hairdresser suggests.  But I would highly recommend this product  to anyone especially with a full head of bleached hair.  Expensive ..yes but I would say it’s worth every penny!Â

Game changer
This - used with the spray mist as a salon treatment, has been a game changer for me. For some years I have experienced significant hair loss - illness & menopause related. After a single application of K18 I noted immediate reduction in hair loss which, after continued use of K18, has decreased to almost nothing /negligible. My hair feels stronger, thicker and styles better when using the products.

An expensive mistake
This is a review based on 6 washes following the instructions. After so much research I finally caved in and invested in k18. I followed the instructions very carefully and even contacted their customer service as to which shampoo I should use. All it’s done is cause so much breakage to my hair, messed up my hair colour and created massive frizz, I’m going to have to get a keratin treatment to fix the damage.Â

A must for my frizzy hair!
I gasped at the price of this at first, but I was so fed up with my thick, frizzy, wavy hair, I thought I'd give it a try. I followed the instructions - apply through hair and don't touch for 4 mins, then I add my curl cream and wow! My hair is smooth with the waves and my curls more enhanced because of it. I only need 1 pump for my chin-length bob - I did overdo it once which left me a bit greasy, so less is more! I'm still on my first bottle, but as I can't see how much is left, I've bought a second one, so I don't have to do without. I'm now stuck buying this as it's changed my hair for the better!

K18 hair mask
I think my expectations were too high. I use Olaplex and love it but it does take time to use. When I read about K18 leave in (wait just 4 mins) then style I thought I’d give it a try. The first time I used it I used 3 pumps, as directed, but my hair (when dry) looked like straw. I tried next time using 5 pumps but this time my hair lacked lustre and was floppy. Not a product for me I’m sad to say.Â

Lives upto the hype
I have very curly coily hair that is coloured, this has definitely strengthened my hair. A little does go a long way. I don't use it all the time every other wash but it definitely an important part of my routine.

Phenomenal
My hair is extra fine, & coloured professionally I also have an under active thyroid that affects my hair.  This is absolutely amazing! I wash my hair most days & also swim a couple of times a week.  Within a week my hair was soft & shiny.  Unbelievable.  I always feel Olaplex treatments need a boost between salon treatments  so the difference is K18 you are using every 3/4 washes.  Expensive but for me worth every penny.

Incredible!
After reading all the great reviews I finally caved in and purchased this to help repair my fine, bleached, and heat damaged hair. I just wish I’d bought it sooner, because it’s absolutely incredible! It’s blown olaplex no.3 out of the water completely for me. I used it exactly as instructed, and in only 2 weeks it’s transformed my hair. It’s so soft and shiny, and has so much body! I’ve all but ditched my straighteners as I hardly need them. It’s so convenient to use as it’s leave in. Two pumps is enough for my long hair, comb through, wait 4 mins, then style as usual. I bought the 50ml bottle, and their website says one pump = 1ml, so I should get 25 uses from it. Yes it’s expensive, but 100% worth it for these results, and I won’t be without it now. I cannot recommend it enough!
