FAQs

How does k18 work?

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 polypeptide chains (keratin chains) in a single strand of hair. When these are damaged, hair’s core structure responsible for elasticity and strength becomes compromised and as a result, it loses its resiliency and shine—or the look and feel of healthy hair. After spending a decade in the lab scanning and testing all amino acid sequences across the entire keratin genome that makes up human hair searching for a breakthrough, that brings damaged hair back to its original, youthful state, K18Peptide™ was discovered.

What is the k18peptide™?

It is a unique sequence of amino acids that travels deep into hair’s core structure to fit in and reconnect broken polypeptide chains (keratin chains) responsible for hair strength and elasticity.

An Analogy: When building proteins, the order of the amino acids determines the kind of protein and its properties, much like the way letters are arranged to make meaningful words and sentences. In the same way, the order and where each word sits in a sentence leads to its overall meaning, K18 is the magic word that fits right in, integrating itself with the keratin chains as the hair recognizes it as a natural building block.

Why should I skip conditioner?

K18 is most effective on clean, towel-dried hair. Conditioners use silicones and conditioning agents that form heavy coatings on hair, preventing peptides from reaching the broken polypeptide chains deep inside the hair’s inner layer.

I noticed there’s alcohol in the formula, isn’t that bad for you?

The formulas are minimal and only use the exact amount of ingredients needed to get the peptide where it needs to go. The unique blend of 3 alcohols functions to open up the hair cuticle so the K18Peptide ™ can penetrate the innermost layer of hair, reaching the broken polypeptide chains (keratin chains). Here the alcohol serves as an agent to optimize the hair environment for K18 to work on a deeper level.

When should I expect to see results?

You will start to see stronger, softer, healthier hair after just one use.

Directions

  1. Shampoo, do not condition. Towel dry until damp.
  2. Begin with 1 pump of K18 Mask and add more as needed depending on the length, thickness, and condition. Work evenly into hair, one pump at a time, from ends to roots.
  3. Let sit for 4 minutes to activate.
  4. Do NOT rinse out. Style as usual.

The Dos & Don'ts

  • DO use a clarifying shampoo if you’re a heavy product or dry shampoo user.
  • DO dry thoroughly with hair towel or turban before application.
  • DO wait the full 4 minutes before styling or applying another product.
  • DO use every 4-6 shampoos consecutively to see and feel the full results.
  • DON’T condition your hair before applying K18.
  • DON’T use too much.
  • DON’T rinse it out.

    My hair is pretty damaged from bleaching every 8 weeks and K18 is such a good treatment and hopefully will reverse some of the damage!
