the new biosciences frontier

DISCOVER KHAIRPEP K18PEPTIDE.™

the science

K18Peptide goes far beyond traditional hair repair. What seems like a miracle is actually firmly rooted in biotechnology. This scientific breakthrough reverses damage to renew hair. Making it soft, shiny, strong again, with bounce.


It’s all about proteins and peptides.

Hair is made primarily of a protein called keratin: what are called ‘keratin-associated proteins’ play a crucial role in maintaining a strong hair shaft, by forming a cross-linked network with 'keratin intermediate filaments'.


Our K18Peptide was discovered from the DNA sequence for hair keratin, the instructions used by the body to build hair. K18 locks the amino acids together as they are naturally meant to be and penetrates into hair’s inner core to interact with the internal disulfide bonds. These bonds — once broken by bleach, color and chemical treatments — are not just repaired or rebonded, leaving it brittle. They are reconformed. Brought back to life. Even better? It doesn’t wash out. The more damaged the hair, the more dramatic the results.

K18 ONLY TAKES FOUR MINUTES TO WORK. AS IF BY MAGIC.
BUT ACTUALLY A DECADE OF RESEARCH IN A BIOSCIENCE LAB.

the history

The K18 Peptide was developed by noted biotechnologist Professor
Artur D Cavaco-Paulo and a team of European researchers, after they discovered a protein fragment called Surfactant Protein D during their research into lung proteins. Surfactant Protein D has a unique ability to diffuse through fats and bind with other proteins—including keratin.

Inspired, Professor Artur and his team mapped the entire active keratin genome expression of hair and after several years of research, the K18Peptide was developed. Today, it remains the only patented peptide that penetrates hair, delivering the necessary amino acids right to the cortex where broken keratin chains are reconnected. This is BIOMIMETIC HAIRCARE in action—the first of its kind—where science recreates the method used by nature to repair hair.

the proof

Clinical results prove K18Peptide renews all hair types compromised by coloring, bleaching, chemical processing, heat and styling damage. Restores hair to near-virgin, unprocessed strength. Even mends split-ends. Results are lasting—K18 won’t wash out. Improvements continue over time, too—the more you use it, the stronger hair will become.

K18 Heals Hair So It
Looks & Feels Like New

UNPROCESSED,
“VIRGIN” HAIR

Cuticles lay
flat with no
visible damage

DAMAGED/
BLEACHED HAIR

Cuticles become
damaged, leaving hair
more porous and
prone to breakage

DAMAGED/BLEACHED HAIR
AFTER TWO AT-HOME USES
OF K18PEPTIDE MASQUE

Hair is restored
to 82% virgin hair
elasticity (without
the use of silicones)

DAMAGED/BLEACHED HAIR
AFTER ONE IN-SALON USE OF K18PEPTIDE SERUM + MASQUE

Hair repair continues from
the inside out; hair is restored
to 94% virgin hair elasticity
and 91% virgin hair strength


K18’s Biomimetic
Hair Repair in Action

1

Broken disulfide bonds
within hair’s cortex
leave hair porous,
brittle, prone to breakage

2

K18Peptide penetrates
the cortex to reconform
bonds as they were
meant to be

3

Hair is brought back
to life, renewed with
softness, shine,
spring and strength


After One Salon Treatment
of the K18 Masque and Mist


The Visible,
Touchable Results

In a consumer study of 52 women
with chemically-damaged hair who
used the K18 Masque seven times,
92% agreed hair felt smoother, 87%
agreed hair felt softer, shinier and
less brittle while 85% agreed hair
had less frizz and breakage.
