Hair transformation in just a few uses!
I’ve tried many repair masks and leave-ins over the years, but K18 truly stands out. My hair is color-treated, slightly dry, and tends to break easily, especially after lightening. After just two uses, I noticed a huge difference, my hair felt stronger, smoother, and looked noticeably healthier without feeling heavy or coated. I love that it works quickly (you leave it on for only 4 minutes) and doesn’t require rinsing afterward. A little goes a long way, so even though it’s pricey, the bottle lasts a while. If your hair has been damaged from coloring, heat styling, or bleach, this product is worth trying. It’s like a salon repair treatment at home. Hair type: Fine to medium, color-treated Concerns: Damage, dryness, breakage Location: Florida Would I recommend it? Absolutely yes!
