Why we love it
The K18 hair mask has made our hair softer than anything else has in YEARS. It works at a molecular level to help repair damage from the inside out. It only takes four minutes, doesn’t require rinsing, and delivers visible results quickly.
After just a few uses, hair feels softer, healthier, and stronger. Corrine said, “It’s the BEST $30 I’ve ever spent on my hair! Literally within 2 washes/uses my hair feels more soft and healthy than it EVER has since I started coloring it in 2015.”
Another reason we love it is that a little goes a long way, so even the mini size lasts longer than expected. The included HIGHLY-rated volume spray is also a great addition, adding lift and fullness without stiffness or buildup.
Don’t take our word for it
The K18 hair mask has almost perfect rating from people who say it helped restore their hair after bleaching, coloring, or years of heat damage. Here are some of the reviews:
“Best product for damaged hair! I use it every other week just once.I don’t colour my hair, but I do have some heat damage and this made a huge difference. My hair is now smooth, shiny, and soft to the touch. I highly recommend it to anyone who’s been waiting to achieve their dream hair!”
“My thin, highlighted blonde hair ALWAYS needs volume and lift! K18 has made it simple and easy for me to achieve this, without leaving my hair greasy or hard to brush. I love this set, and I think it's a great gift, too!”
“I love this mini set. I love using this leave in treatment it leaves my hair soft, manageable and my hair has been looking so much healthier. I have been noticing improvements in my hair specifically how stronger my hair feels. I also like using there volume spray before blow drying my hair it gives my so much volume and texture to my hair without weighing it down. I like how it helps control frizz. I think it’s a perfect set for travel or as a gift.”
