Silky soft hair
My hair is blonde and super damaged, even after one wash and blowdry it feels and looks so much healthier and soft. Can’t wait to use it consistently! You have to use to to the instructions on the box otherwise it’s not worth it!

Amazing product
Have noticed such a difference using this on my damaged, bleached hair! Much better than olaplex for me and have been using it consistently

Amazing
I have been bleaching my hair for years and have been struggling to find something that actually helps with the damage. I have tried other treatments like Olaplex but have found them to make my hair break off. I have really noticed a difference in the length of my hair while consistently using this product.

Transformative
This completely repaired my dry and colour damaged hair. My hair was dry and frizzy before this. Now it is smooth, silky and “fixed”. It feels strong and complete again rather than frizzy and split. I had to use a lot more than 3 pumps but I have a lot of hair. I also used the K18 oil on the ends. Glad I got this rather than Olaplex. This is more transformative. I say this as someone who has unruly hair and most things don’t have much of an effect on it.

Rescued my hair
Had a little dalliance with some bleach and box dye over the festive period which left my hair in that fun chewing gum state. I cried to my hairdresser as she cut in lots of layers and she recommended K18. I didn’t hold out much hope but it’s sooo good and has left my hair feeling like actual hair. Have already repurchased the full size.
