This powerful repair and styling duo combines the transformative benefits of the K18 leave-in molecular repair mask and the biotech-engineered weightless hair oil, both powered by the patented K18PEPTIDE. The leave-in treatment mask works on the molecular level to reverse damage from bleach, color, chemical services, and heat in just four minutes—restoring strength, softness, smoothness, and bounce with immediate and lasting results. Paired with it, the lightweight hair oil strengthens and repairs damage across all hair types while reducing frizz at both the inner and outer levels of the hair fiber. The K18PEPTIDE penetrates deeply to address the root causes of damage and frizz, while a blend of natural oils—including avocado, sunflower, hemisqualane, and squalane—nourishes and smooths the surface. Together, they improve color vibrancy, enhance shine, tame flyaways, and provide up to 450°F (232°C) heat protection, delivering visibly healthier, more manageable hair.
