    • STOP LOOKING. This is THE ultimate hair saver!!! ⭐️⭐️⭐️⭐️⭐️
A set of this K18 conditioner and shampoo was gifted to me by my stylist and it literally saved my hair! My hair would break due to color treatments and blow drying. I would find clumps in the shower drain and strands all over the place. I have coarse, thick, Asian hair and would measure its thickness by the width of my ponytail. It was definitely thinning out. Since I started using K18, I've seen a noticeable change. It's much smoother without being weighed down. It feels fuller and there's hardly any broken hairs anywhere! I highly recommend this for anyone who has damaged hair. It's worth every penny! ... show more

    • I love this!
This conditioner makes your hair extremely soft! It has saved my hair from splitting, and adds a nice shine to the hair. Even better when you combine it with the leave in conditioner, it adds maximum hydration! I didn’t even know, I had curl to my hair until I used this product! It’s amazing!

    • Amazing
Great project for my damaged hair. This really helped my fried hair. It works wonderfully. Smells good too. After a month my hair did look better.

    • Helped my SEVERELY damaged hair!!
I have bleached my hair on so many different occasion! This last time, my hair ended up getting severely fried and damaged! I truly cannot tell you, how many products I have tried to help my hair in any which way. The first wash with the K18 conditioner, I let the conditioner sit in my washed hair for about 10 minutes, and I could tell the difference as soon as I got put of the shower. I could easily brush through my hair and when my hair dried, it was the softest it has been in so long! Definitely recommend to others who have dry or damaged hair! ... show more

    • Perfect for my hair
I am a post kidney patient that was advised to be aware that I could experience hair loss and dry brittle breakage. This was initially introduced to me by my stylist who had my best interest at heart. So happy I tried. I love it. It has turned my hair into my shiny hair again. Re growth is happening. Quality is top notch and smells amazing. A+++ ... show more
Reviewed in the United States on June 24, 2024 by Great read, it was a gift for my son. He is a huge Disney Fan and shared this book with friends on social media, and spoke highly about the illustrations. Highly recommend
    • This stuff is amazing!
I recently lightened my curly hair and it was suffering badly. After only one use of K18 conditioner, my hair is back to its soft natural state. I swear by the conditioner and plan to keep it a part of my regular hair care routine.

    • My new favorite product
I was introduced to this brand by my stylist. I use this and the shampoo combo and it leaves my hair healthy and shiny. You don’t need to use a lot as it’s concentrated and goes a long way.

    • Not worth it
I had high expectations on K18 but honestly I’m disappointed. My hair isn’t soft after using this
