Where science meets hair care.

K18’s patented formula boasts a unique sequence of amino acids through the struggling strands to reconnect. K18 is powered by the patented K18Peptide, which is just the right size and molecular structure to reach the innermost layers of hair and re-connect broken keratin chains responsible for hair's strength and elasticity.

In a clinical study on hair that was bleached 8 times, after 2 uses Biotech-powered K18PEPTIDE restored damaged hair by up to 82%.

K18 is usable for all hair types.
