The K18PEPTIDE™, the heart of K18’s technology
K18’s Philosophy: The Fusion of Science and Nature
K18’s innovative haircare range- K18 leverages patented technologies to address the most complex hair concerns at their core.
Inspired by human biology and natural solutions, its formulas work deeply to:
Repair: The K18PEPTIDE™ reconnects keratin chains broken by external aggressors (bleaching, heat, chemical treatments).
It acts at the molecular level, repairing damaged bonds (polypeptide chains and disulfide bonds) to reverse damage caused by coloring, bleaching, chemical services, or heat. Designed through biotechnology, this peptide is optimized to seamlessly integrate into the hair’s natural keratin structure, like a key in a lock. It reconnects damaged sites at the molecular level, delivering lasting repair for all hair types, restoring strength and elasticity.
Effective in just four minutes, with no extra steps, and visible results from the first application.Protect: resilicore™ technology penetrates deep into the hair’s core for optimal heat and UV protection.
Unlike traditional heat protectants that merely coat the cuticle, its molecular size and structure allow it to penetrate to the cortex—where heat damage runs deepest.
Inspired by nature’s most heat-resistant proteins, this shield fortifies hair from within, providing maximum defense against color fade, dryness, dullness, and breakage.Deodorize: odorBIND™ captures and eliminates odors for fresher hair, even after intense workouts. K18’s scientists harnessed genetic databases to replicate nature’s most powerful olfactory systems.
This smart molecule traps, neutralizes, and eliminates unwanted odors, rendering them undetectable while releasing a subtle, natural fragrance.
