    • 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.

    • K18 Conditioner
Great product. Used until I ran out of the item. It worked well but didn’t reduce the shedding issue I was having. Great slippage, no scalp irritation . Leaves your hair manageable, hydration, little to no scent, great product.

    • 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

    • 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

    • Not worth it.
There was no improvement in my hair texture or manageability. I decided to try this product after putting highlights in my hair. It did absolutely nothing, my hair was difficult to brush through and unmanageable. I went back to Puerology Hydrate and immediately saw the difference. Save your money and get Puerology or Olyplex. ... show more
