Absolutely amazing, I’m late to the party with this one but wow this transformed my dull hair.Â

Great product.
Great product, I use very occasionally when hair is feeling a bit damaged. 4 stars because the product is expensive and I tend to have to use a bit more than on the instructions to get through my hair. Hair type: curly

Essential purchase
Ok so I colour my hair, and there is NO OTHER product that matches what K18 does. I have tried rebond from the salon and oleplex and will go back to expensive k18 because simply it works and quickly. Just buy it, your hair will thank you later

Amazing product
This is pricey and I had it on my wish list for ages but I'm so glad I tried it. My hair is quite knotty and tangly but using this made it so soft and happy :-) I will definitely repurchase!
