The K18 Biomimetic Hair Science Leave-In Molecular Repair Hair Mask is clinically backed to reverse damage in a jiffy. Packed with a patented Peptide Technology, it repairs harm from bleaching, coloring, chemical applications, and heat - reconnecting broken keratin chains to give you stronger, softer, smoother, and bouncier locks! Just one use and you'll be able to see and feel the difference. The K18 Molecular Repair Hair Oil is formulated with a potent blend of K18PEPTIDE™, avocado, and sunflower oils, while hemisqualane and squalane work in tandem to strengthen your hair fiber and nourish from the surface up.
