K18 Peptide Prep pH Maintenance Shampoo is a cleansing shampoo micro-dosed with the patented K18PeptideTM. Powerful yet non-stripping formula is designed with an optimised pH that is safe enough for everyday use.

It cleanses while smoothing the hair surface: Effective yet safe cleansers break down and remove dirt + oil for optimal nourishment and manageability.

Designed for daily use: pH-balanced formula doesn’t disrupt the hair fiber or scalp environment and is safe to use daily if needed.

Creates the ideal foundation for healthy hair: This formula was engineered to create an optimal clean canvas without any fillers to coat or disrupt the hair and scalp equilibrium.

Less is more formulation delivers a superior clean without compromise: Optimised pH keeps the cuticle closed during washing and protects hair’s natural moisture levels for a smooth hair result. Plant-derived surfactants create high foaming + cleansing power without being harsh or leaving buildup behind on hair or scalp.

K18Peptide works as a protective shield to reduce protein loss that can occur during washing to keep hair feeling soft, strong, healthy and clean.

      As self-described hair care ‘liberators’, K18’s ethos is all about supplying you with the tools you need to express your identity, try new trends and have fun with your mane — without sacrificing the softness, strength and vitality of your hair.

      By understanding the biology of your hair the K18 team has been able to get to the (*ahem*) root of the problem of hair damage, and — crucially — discover one hero bioactive peptide that will return strands back to their most healthy state.

      Enter: the K18Peptide, a patented molecule that travels to the polypeptide chains (that’s the very innermost layer of your hair) where it repairs broken bonds and restores hair’s strength and elasticity. This is where biotech meets hair care!
