K18 Leave-in Molecular Repair Hair Mask is an at-home, four-minute treatment powered by the patented K18Peptide™. Unlike traditional masks that sit on the surface, this lightweight balm penetrates deep into the inner cortex, reconnecting broken keratin chains to renew hair strength, elasticity and shine. You’ll feel noticeably softer, smoother and more resilient strands from the very first use.
Ideal for hair weakened by bleaching, colouring, heat styling or chemical treatments, K18’s biomimetic peptide technology restores your hair’s youthful “memory” without weighing it down. Simply apply after shampoo, wait four minutes, and style as usual—no rinse required.
