backed by science, loved by stylists

Our community of stylists and colorists in 33 countries believe K18 is liberating hair—no matter the hair type or generation.

“Oh my gosh—my hair feels so awesome. I can’t stop putting my hands through it...I have had a terrible relationship up until recently with my hair, I have to admit. Growing up, I had frizzy hair, I have hair that curls but doesn’t curl well, and so it’s hard for me to like my hair. And I have to say, right now—I LOVE my hair.”

- Diane, K18 with color

“K18 allows me to go everywhere I want to go with my color work and the end result is my guests get to be bright and shiny and healthy.”
– Christine Thompson, Director of Color at Spoke & Weal

"What I've found with K18 whether I'm using the MIST or the MASK, is that I can get that hair to do exactly what I want, it has the strength and integrity that I'm looking for, and it looks AND feels amazing which to me is a gamechanger."
- Jon Reyman, Founder Spoke & Weal

where biotech meets haircare
