about K18

a radically different approach

Until now, haircare products covered up damage with conditioning treatments that coat hair in oils, bringing superficial hydration and sheen, while repair treatments patch damage like internal glue – strong but brittle—and provide temporary results. K18 is the first product that actually heals your hair from the inside out.




Conceals Damage

Patches up and hydrates the outer layer of hair without repairing broken bonds in the core. Smooths over, a temporary fix.


Patches Damage

Repairs broken bonds in the cortex - but does so like a fixed hard 'glue'. Does not restore elasticity and washes out over time.

The Science

K18Peptide™ is a oligo peptide formulated to shuttle amino acids (the building blocks of hair) into the inner structure of the hair. Once inside the hair, the unique amino-acid chain bonds with the hair keratin protein to reverse damage by reconnecting the broken disulfide bonds, bringing strength and elasticity to near virgin state and restoring hair’s health, shine and manageability.

Clinically proven to penetrate and repair damaged hair

Using fluorescence microscopy, independent researchers showed that K18Peptide™ penetrates into the hair cortex, bonds with hair proteins – and remains even after daily shampooing.

Clinically proven to add strength


Repairs bleached hair

When hair that had been bleached 8 times was treated with K18Peptide™, the hair strength increased by up to 85%.

Repairs relaxed and straightened hair

Virgin hair was relaxed with a strong alkaline/guanidine solution to produce intense straightening conditions, then treated with K18Peptide™. The result was an over 90% recovery of hair strength.

Clinically proven to improve hair elasticity

Improves elasticity

Independent clinical tests verified an up to 120% improvement in elasticity.

Results improve with repeated treatments

Repeated applications saw up to an additional 41% increase in hair strength.
