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
