K18 Leave-In Molecular Repair Hair Mask 50 ml

K18 reset expectations for hair repair. The Leave-In Molecular Repair Hair Mask uses a patented peptide that mimics the keratin chains in hair, reconnecting broken keratin chains to restore strength, softness and elasticity.

It replaces conditioner on treatment days: shampoo, skip conditioner, towel dry, apply a small amount, wait four minutes and style as usual. Results build over the first four to six uses, then maintenance every few washes.

A pea-sized amount covers shoulder-length hair. 50 ml tube.
