K18 is a revolutionary, biotechnology-driven hair care brand that’s changing the way we think about damaged hair. Using a patented bioactive peptide — K18Peptide™ — this breakthrough treatment repairs hair at a molecular level in just 4 minutes.

Unlike traditional conditioning treatments that simply coat the surface, K18 works from the inside out, reconnecting broken polypeptide chains and disulfide bonds to restore hair to its original, healthy state.

What does K18 repair?

• Damage from bleach and lightening services
• Colour and chemical service damage
• Heat damage from styling tools
• Years of accumulated wear and environmental stress

Who is K18 for?

K18 is suitable for all hair types. Whether your hair has been through multiple colour sessions, years of heat styling, or chemical treatments, K18 can reverse the damage and restore strength, softness, and elasticity.

It’s also vegan and cruelty-free — exceptional science without compromise.

How does it work?

Applied as a leave-in treatment during your salon visit, K18 gets to work in just 4 minutes. There’s no need for lengthy processing times or complicated aftercare — just visibly stronger, healthier hair from your very first treatment.
