K18 Leave-In Molecular Repair Hair Mask 50ml

Transform damaged hair in just minutes with the K18 Leave-In Molecular Repair Hair Mask, an award-winning professional hair treatment powered by patented K18PEPTIDE™ technology. Unlike traditional conditioners or protein treatments that only coat the hair, this innovative leave-in mask works at the molecular level to help repair damage caused by bleach, color treatments, heat styling, and chemical services.

The lightweight, leave-in formula helps restore hair strength, softness, smoothness, and elasticity while reducing breakage and frizz. Hair feels healthier, shinier, and easier to manage after continued use—without weighing it down.

Suitable for all hair types, including straight, wavy, curly, and coily hair, the K18 Molecular Repair Hair Mask is an essential treatment for anyone looking to revive dry, damaged, or over-processed hair.
