K18 Leave-In Molecular Hair Mask is a breakthrough professional treatment designed to reverse years of damage caused by bleach, color, chemical services, and heat styling. Powered by the patented K18Peptide™, this advanced formula travels deep into the hair cortex to rebuild keratin chains and restore broken polypeptide bonds—repairing hair at a true molecular level. Unlike traditional conditioners or masks that only coat the surface, K18 works from the inside out, delivering long-lasting strength, flexibility, and resilience.

This leave-in mask brings visible transformation in just 4 minutes, making it one of the fastest and most effective hair-repair solutions available. Whether your hair is extremely damaged, dry, brittle, or chemically compromised, K18 instantly improves softness, smoothness, and shine. The lightweight cream formula absorbs quickly without weighing hair down, making it ideal for all hair types—straight, wavy, curly, coily, fine, thick, or chemically processed.

K18 Leave-In Molecular Hair Mask is cruelty-free, vegan, and free from sulfates, parabens, silicones, and artificial dyes. By using biotechnology instead of heavy cosmetic coatings, K18 delivers real structural repair that lasts even after washing. With continuous use, hair becomes noticeably stronger, healthier, and more vibrant.

To use, simply shampoo your hair, skip conditioner, towel-dry, and apply 1–3 pumps depending on hair length and thickness. Leave in for 4 minutes to let the peptide activate, then style as usual. Over time, K18 helps reverse cumulative damage, rebuilds elasticity, and restores natural bounce.
