Truly a Game-Changer for Damaged Hair!

5 stars out of a maximum of 5

Truly a Game-Changer for Damaged Hair! I have shoulder-length, highlighted blonde hair (touch-ups every 8–10 weeks), and over time it became thin, dry, and prone to breakage. When I came across this hair repair mask, I was initially hesitant due to the price, but I’m so glad I decided to give it a try. The results have been incredible. My hair feels stronger, healthier, and noticeably smoother. Even my hairdresser asked what I’d been using! The instructions recommend shampooing and skipping conditioner, which made me nervous at first, but the transformation speaks for itself. Yes, it’s on the pricier side, but in my opinion, it’s worth every penny. It deeply nourishes and truly repairs damaged, over-processed hair. This has quickly become my must-have treatment, and I’ll definitely be repurchasing. If your hair is weak, dry, or breaking from colouring or heat styling, this is the product for you!

great for when my hair felt super weak and damaged. having had a good trim and avoided bleach for a year, it’s no longer necessary and a bit expensive for my day to day hsircare

This is an amazing product! Leaves any hair feeling soft and manageable while treating it. Helped my damaged over processed color treat 4c hair come back to life. It’s magic but it really works!

Miracle in a bottle

5 stars out of a maximum of 5

I have been recovering from bleach damage, colour damage and heat damage for the last 3 years and my hair was just missing something until I finally caved in and bought this! My hair has never felt better, looked better. It is wonderful! However, you have to use it correctly. (Shampoo 2x, k18 for 4 minutes, then apply conditioner and rinse!!) If not your hair will still feel dry and stringy as k18 isn’t a hydration treatment. I absolutely love this product and it definitely is worth the high price tag especially because you only need a tiny amount.

Love, love, love

5 stars out of a maximum of 5

This is my third purchase and I love it! I've recently had highlights in my curly hair. I used this before my appointment and after. It's definitely kept my hair healthy and my curls bouncy and full of volume. Yes, it is expensive but you only need a small amount and it's probably one of the most effective hair products that I have ever used
