K18 Biomimetic Hairscience – Repair Hair Like Never Before

Real repair. Real science. Real results.
K18 isn’t just another haircare brand—it’s a biotech breakthrough that changed everything we thought we knew about damaged hair. Born at the intersection of biology and beauty, K18 Biomimetic Hairscience has developed a radically new approach to hair repair, using patented molecular technology to restore hair from the inside out—permanently.

No surface gloss. No temporary fixes. Just clinically proven science that reverses hair damage at the core.

The Science That Started a Haircare Revolution

At the heart of K18 is the K18Peptide™—a patented molecular innovation developed after 10 years of bioscience research. Scientists at K18 decoded the human hair genome, analyzing how keratin proteins are structured, bonded, and broken during chemical, thermal, and mechanical damage.

Their discovery? While other products coat the hair or temporarily patch damage, true repair only happens by reconnecting the broken polypeptide chains that form the inner structure of hair. This led to the creation of K18Peptide™—a biomimetic peptide that travels deep into the hair shaft and reconnects these broken bonds, restoring strength, softness, and elasticity from within.

It’s the first technology of its kind that heals damaged hair permanently in just 4 minutes—with results that get better over time.

What Makes K18 Different:

• K18Peptide™ Technology: The only patented peptide clinically proven to reverse damage from bleach, color, heat, and chemical treatments.
• Works in Minutes, Not Months: See visible transformation in a single use—and cumulative results with consistent application.
• No Rinse Needed: Unlike traditional masks, K18’s signature treatment is a leave-in formula that continues to work as you style.
• Backed by Science, Loved by Stylists: Used in top salons worldwide and trusted by professionals to restore even the most compromised hair.
