Small but mighty

5 stars out of a maximum of 5

Recommend by my sister who was recommended by a friend. Makes a noticeable difference to the quality of dyed hair. The bottle is small but it goes a long way.

Good product but not groundbreaking

4 stars out of a maximum of 5

I like this product and I bought primarily for a trip overseas where I have luggage restrictions and I had to downsize everything. I have long fine hair, and although the product kept me going for 10 days I switched back to olaplex (pre and post shampoo) as soon as I came back. It did the job but I did not notice anything as groundbreaking as the glossy magazines reported

The bottle is very small and after a few washes it made my hair feel a bit softer. Olaplex better

Magic in a bottle!

5 stars out of a maximum of 5

This product is very expensive but in my opinion worth every penny. I have been using the k-18 leave in hair mask for a couple of years now, and it has transformed the health and texture of my hair! My hair is bleached and this keeps it looking healthy and soft, and reduces split ends and breakage. It’s also really easy to use, and unlike most bond repair products can be used after washing your hair (pre conditioner), and only takes 4 min to work. This means I am far more likely to consistently use this compared to other similar products. Would highly recommend!

This is the best hair mask

5 stars out of a maximum of 5

This is the best hair mask I've ever used. I have bright red hair which is bleached and then dyed, so it's always in pretty poor condition. This hair mask has saved my hair, it makes it feel so soft and is in much better condition than if I didn't use the mask. This is my third purchase - an absolute must for me.

Works on split ends

5 stars out of a maximum of 5

I’m very impressed with this leave in treatment, it’s probably the only product I’ve used that has actually corrected and repaired/re-bonded the split ends on my bleached hair so they’re no longer like candyfloss and that’s after only 2 applications! The improvement is dramatic and long lasting. The bottle is tiny but 3 pumps is enough for my long hair. Only negative is you can’t use conditioner prior to applying as this only works on pre shampooed hair as conditioner would stop it from absorbing and because I’m only applying to my split ends it means the rest of my hair is a bit dry from not using conditioner.
