K18 Molecular Repair Hair Mask 50ml



leave-in molecular repair hair mask

10 years of biosciences research 

 1 breakthrough peptide.

K18Peptide™ (formerly Khairpep) was patented after scanning and analysing 1,242 deca-peptides that cover the entire genome of human keratin proteins.
After a decade of research, the inventor discovered one unique sequence unlocking the science to bring strands damaged from chemical services and thermal/mechanical styling back to their original, youthful state — the K18peptide.

Patented K18 is not just a temporary fix — it is the first product to utilise biomimetics to reconnect keratin chains once broken by bleach, colour, and chemical services, resulting in soft, smooth, strong hair with bounce that feels like new.
The more damaged the hair, the more dramatic the results.

Heal Your Hair 

K18 before and after


K18 Peptide™

it starts with science

The only patented bioactive peptide treatment clinically proven to repair hair and reverse damage from chemical services, thermal styling, and mechanical styling. For all hair types. #k18hair

Usage: Shampoo, do not condition. Towel-dry throughly.
Begin with 1 pump of K18 Mask and add more as needed depending on length, thickness, and condition.
Work evenly into hair from ends to roots, one pump at a time. 
Let is sit for 4 minutes to activate. Do not rinse out.

Use for the first 4-6 washes, and then every 3-4 washes as needed.

    - Lightweight, cream consistency

    - Great for longer hair types, medium to thick hair, knotty hair and curly hair.

    - K18 MOLECULAR REPAIR MASK has detangling properties making it easy to distribute and comb through the hair after shampooing

    - Fast absorbing and lightweight, you do not notice the product weight being left in your hair

    - pH 5.4 helps in rebalancing chemically altered hair back to it's natural pH 5.5 - 6.5

    - locks down the cuticle for increased shine and resilience

    K18 works by reforming the disulphide bonds and reconnecting the keratin chains in damaged hair. These bonds make the hair more resilient.

    The K18 peptide transforms damaged hair into hair with greater flexibility and resistance, scientifically proven. This groundbreaking new technology surpasses any other product on the market when it comes to repairing hair damaged by chemical services and heat styling.

    Unlike 'plex' products that are mixed with colour and bleach during chemical services, K18™ provides a simpler and more effective solution that doesn't wash out overtime.

    Khairpep K18 is a treatment like no other; being a peptide based treatment, a leave-in treatment and contains 18 of 23 amino acids, it works to reconnect broken keratin chains by carrying amino acids back into the core of the hair and restoring the hair's overall integrity, adding shine and improving elasticity.

    Hair is made up of a protein called Keratin, the inner core of the hair contains Disulphide bonds and Hydrogen bonds that help keep the hairs heath and integrity intact.

    When the hair becomes damaged from colour, chemical relaxers, hot tools, environmental aggressors and more, the Disulphide bonds often break - this causes the hair to become weak and damaged.

    When we wet and shampoo our hair the Hydrogen bonds break, however, they reset when the hair is dried.

    For K18 to work, the hair needs to be shampooed and wet (hydrogen bonds - broken) so the cuticle is open, creating an entrance portal to the inner structure of the hair.

    The K18 can then travel into the hair and release the amino acids.

    Once in the hair the amino acids work like a transplant, re-linking and repairing the broken keratin chains and disulphide bonds.

    In turn restoring hair back to almost virgin-like quality!

    K18 then remains in the hair, no rinsing out and no conditioning, sealing itself inside the inner structure of the hair.

    Only Used Once

    I’ve only used it once and it does make my hair look good but there’s not much product in the bottle, I’ll only get 3 applications from it so it works out a bit expensive.

    Incredible Mask

    I am incredulously running my hands through my new hair. It was bleach damaged to say the least but now feels virginal. Amazing product.
