With our revolutionary K18Peptide, we are able to create hair that looks and feels like new by traveling into the inner-most layers of the hair to reach the core polypeptide chains, reconnecting broken chains responsible for hair strength and elasticity. Our products transform even the most extreme damage into hair that looks and feels like new for all hair types and generations.

The K18Peptide mimics the natural building blocks of hair and integrates itself with the keratin chains to rebuild and restore hair immediately and over time. This patented biotech treatment renews chemically damaged hair from the inside out in just 4 minutes, restoring strength, softness, smoothness, and bounce.
