A now must-have in my hair routine!
I tried the K18 Leave-In Molecular Repair Hair Mask after coloring my hair and used it for my first four washes as recommended. It was super easy to use, just applied it after shampooing and skipped the conditioner. After a few uses, my hair felt noticeably softer, smoother, and less damaged. By the fourth wash, it looked healthier overall without feeling weighed down. Definitely worth it if you want a simple, effective repair treatment!
