Wonderful product!
Superb Product, worked very well on the health of my heavily bleached hair. It’s expensive, but worth it. A game changer!

It actually works!
I box dye my roots/whole head every 5 weeks, so my hair takes a lot of damage. Since using K18, there’s clearly less breakage when I wash/brush/style my hair. Worth every penny!
