Repair the look and feel of damaged hair in just minutes with the K18 Future Society Leave-In Repair Mask. This limited-edition collaboration pairs K18’s biology-first molecular repair with an exclusive, biotech-engineered fragrance inspired by extinct flower DNA.

Powered by patented K18PEPTIDE™ technology, this lightweight, leave-in treatment works deep within the inner cortex to reconnect broken polypeptide chains and disulfide bonds. It reverses the visible effects of damage caused by heat styling, chemical services, bleach, and environmental stressors, restoring a healthier-looking, smooth, and manageable finish without weighing the hair down.
