where biotech meets haircare

After spending a decade in the lab scanning and testing all amino acid sequences across the entire keratin genome that makes up human hair, we discovered one unique sequence (a bioactive peptide) that brings damaged hair back to its original, youthful state.

This is our K18Peptide™- the patented molecular breakthrough clinically proven to reverse hair damage in 4 minutes from:
bleach + color bleach + color

get inside the world of hair

Traveling into the inner-most layers of hair to reach the core polypeptide chains (keratin chains), our revolutionary K18Peptide™ is just the right size and makeup to fit in and reconnect broken chains.
more product does not equal better hair
Traditional conditioning products conceal damage. They patch up and hydrate the outer layer of hair without repairing broken bonds at the core. A temporary fix, but the damage is still there.



Traditional rebonding products patch damage. They repair broken bonds in the cortex, but they act like a hard glue, washing out with water. A temporary fix, but will wear down over time.
HAIR WAS NOT MADE FOR PRODUCT
Everything you add to your hair makes it needier, requiring more attention and product, causing more unnecessary stress to strands and so on…it’s a vicious cycle. Hair is not made to have products sitting on it.

We discovered that hair looking good does not necessarily translate into hair feeling good—and that healthy hair needs less product.
DAMAGE DOES NOT HAVE TO BE PERMANENT
Reverse years of damage in 4 minutes with peptide-powered renewal. K18 restores hair’s core strength + elasticity for lasting strength, softness, smoothness, and bounce that only gets better with each use.

the science

The science is complex but here’s everything you need to know about why K18 is a scientific breakthrough—and how it can bring damaged strands back to their original, youthful state.

When hair gets damaged, the polypeptide chains (keratin chains) that make up the inner structure of hair strands become weakened and break. For context, there are billions and billions of keratin chains in a single strand of hair. When these are damaged, hair’s core structure becomes compromised and, as a result, it loses its strength, elasticity, resiliency, and shine.

the discovery

Our answer to damaged hair? The K18Peptide™. Traveling into the inner-most layers of hair to reach the core polypeptide chains (keratin chains), our revolutionary K18Peptide™ is just the right size and makeup to fit in and reconnect broken chains.

And because our peptide is a bit of an overachiever, as a result of this reconnection, any disturbed disulfide bonds are also re-conformed.

hair strength where it matters

The breakage along the y-axis (length) must be repaired or reconnected in order to restore hair strength and elasticity or as we like to call it: genuinely healthy hair.

have questions?

we have answers.

There is alcohol in the formula. Isn’t that bad for my hair?

The three alcohols in our formula work together on a scientific level to open the hair cuticle and act as the vehicle to carry our peptide further into the innermost layers of hair to reach broken polypeptide chains. This repairs the structural integrity of hair, renewing strength, softness, smoothness, and bounce.

Why is it important to apply K18 to clean hair?

In order to work most effectively, K18 needs to be able to reach that innermost part of hair. Buildup from other product can sit on hair making it hard for our peptide to penetrate at full force. Clean hair ensures K18 can make it all the way to the inner layers reaching the polypeptide chains (keratin chains), and renewing strength and elasticity when it gets there.

Why do I need to skip conditioner when using K18?

Traditional conditioners coat the outer layers of hair in an attempt to patch up damage. This also causes buildup, making it hard for our peptide to penetrate at full force. Clarified and cleansed hair ensures K18 can make it all the way to the inner layers reaching the polypeptide chains (keratin chains), and renewing strength and elasticity when it gets there.
