K18 Leave-In Molecular Repair Hair Mask

A 4-minute leave-in treatment to clinically reverse hair damage and split ends.

An at-home leave-in treatment infused with the patented K18Peptide™ that works on a molecular level to repair even the most extreme damage, reversing hair to its most youthful, healthy state—leaving strands soft and strong.

Perfect to use after hair lightening, colour, perms, relaxers, thermal reconditioning, keratin straightening, general treatments, and even after a simple haircut. Even ideal for treating damage caused by the sun, heat, products, water and environmental aggressors.

creates hair like new
Traveling deeper into the inner layers of hair than traditional repair products, the revolutionary patented K18Peptide™ is just the right size and makeup to fit in and reconnect broken keratin chains, renewing hair with strength, softness, smoothness, and bounce. You can feel and see the difference after the first use.

See dosage chart for exact usage. For best results, use for the first 4-6 consecutive washes following a service, then every 3-4 washes as needed to maintain hair strength.

results don’t just wash away
The K18Peptide™ mimics the natural keratin building block structure in the hair, and is recognised as natural by the hair instead of a facilitated bond – so it perfectly integrates itself within keratin chains to rebuild and restore hair immediately, and over time. That means it’s not washed away by water or shampoo, like traditional bonding agents. K18 is a genuine and lasting damage solution.

K18 cannot be overused. There is no need to worry about using too much formula for your hair type, length and thickness.

  1. Shampoo, do not condition.
  2. Towel dry thoroughly.
  3. Begin with 1 dime-sized amount (about 1 ml) of the K18 Mask and add more as needed depending on the length, thickness, and condition of your hair.
  4. Work evenly into hair from ends to roots, one portion at a time.
  5. Let sit for 4 minutes to activate.
  6. Do NOT rinse out.
  7. Style as usual.

Description

hair like new

no matter what you put it through

 


The award-winning hair care brand has landed in South Africa.


A breakthrough in biosciences

K18Peptide™ was patented after a decade of scanning and testing the 1,242 decapeptides that cover the entire genome of human hair keratin proteins. The K18Peptide™ is the one unique sequence unlocking the science of transforming damaged hair back to its original, healthy state.

Patented K18 is not just a temporary fix — it’s the first product to utilize biomimetics to reconnect keratin chains once broken by bleach, colour and chemical services, resulting in soft, smooth, strong hair that feels like new. No more worrying about damage sitting in the salon chair. Now you have a healthy, clean canvas of strong hair.

The more damaged the hair, the more dramatic the results.

 

For all hair types, for every generation.

This is BIOMIMETIC HAIRSCIENCE — a new frontier in the hair industry.

Heals hair in 4 minutes.


A radically different approach to hair damage.

Until now, hair care products covered up damage with conditioning treatments that coat the hair in oils, bringing superficial hydration and sheen. Repair treatments patch damage like internal glue – strong but brittle — but provide temporary results.

K18 is the first product that actually heals your hair from the inside out. K18 is clinically proven to undo hair damage caused by chemical services, thermal styling, mechanical styling, and environmental damage.

Damage is universal, and now lasting repair can be too.
