where biotech meets haircare
After spending a decade in the lab scanning and testing all amino acid sequences searching for a breakthrough within the entire keratin genome that makes up hair, we discovered one unique sequence that brings damaged hair back to its original, youthful state – our patented K18Peptide™.

radical simplicity
We believe in simplifying the hair routine. After 10 years of complex lab research, we unlocked the peptide that makes everything else simple. K18Peptide™ gives us the freedom to liberate your routine and self-expression.
