A leave-in treatment mask that works on the molecular level to reverse hair damage in just 4 minutes. The K18PEPTIDE is clinically proven to repair damage from bleach + color, chemical services and heat, with immediate and lasting results to restore strength, softness, smoothness and bounce to hair.

Key Benefits 🌟

🌟 Takes damage repair further – reconnects both polypeptide chains (and as a result, also reconnects disulfide bonds) for strength along the length + width of the hair - offering comprehensive, lasting damage repair.

🌟 Restores hair from even extreme damage - by working at the innermost layer of the hair, core strength and elasticity are renewed for strong, smooth, bouncy hair.

🌟 Delivers immediate and lasting results – hair is repaired from the first use and lasts past your next wash, for ongoing reparative benefits.

🌟 Simplified repair - convenient, leave-in formula works in just 4 minutes, with no extra rinse required.

🌟 Works on all hair types – because K18PEPTIDE works on a molecular level (where all hair is the same), this product is effective on all hair types.

How To Use 🎯

  • 1. Shampoo, do not condition. Towel-dry thoroughly.
  • 2. Apply 1-3 pumps of K18 molecular hair repair mask based on your length and density, starting at the ends and working up towards the roots.
  • 3. Let sit for 4 minutes. Do not rinse out.
  • 4. Comb, add product + style as usual. Use for 4-6 washes post-salon service, then as needed.

DOs & DON'Ts 🔑

  • ✅ DO clarify before K18 if you’re a heavy product user (demineralize for mineral + metal buildup).
  • ✅ DO apply on clean, damp hair.
  • ✅ DO wait the full 4 minutes before combing or styling.
  • ✅ DO add whatever styling products you love after the 4 minutes.
  • ✅ DO use for 4-6 shampoos consecutively for progressive results.
  • ❌ DON'T use conditioner before applying K18 Mask (you can apply after the 4 min but most find they don’t need it).
  • ❌ DON'T overdo it, less is more.
  • ❌ DON'T rinse it out.

FAQ

Any questions?

How Does The K18 Mask Work?

The K18 mask works as a treatment to reverse damage in 4 minutes. It’s powered by our biomimetic K18PEPTIDE
to seamlessly fit in and reconnect broken polypeptide chains at the
molecular level. As a result, disulfide bonds are also reconnected for
reinforced strength along the length + width of hair, offering
comprehensive, lasting, and progressive repair.

What is The K18PEPTIDE?

K18PEPTIDE is a biotech-developed peptide that mimics hair’s structure to reverse
damage by reconnecting polypeptide chains and disulfide bonds broken
during damage from bleach + color, chemical services, and heat*


When Should I Expect To See Results?

Most see results after 2-3 uses. The more damaged the hair, the more
dramatic the results so it may vary depending on your hair type and
level of damage.


Aren't The Alcohols Bad For You?

No, we like to keep our formulas minimal, only using the exact amount of
ingredients needed to get the peptide where it needs to go. Here the
alcohol serves as an agent to optimize the hair environment for the K18
mask to work on a deeper level. Our unique blend of 3 alcohols functions
to open the hair cuticle so the K18PEPTIDE can penetrate the innermost layer of hair, reaching the broken polypeptide chains (keratin chains).


Why Do We Skip Conditioner?

Conditioner leaves a film that blocks our peptide from penetrating
effectively. Once the 4-minute wait time is up, feel free to use a
conditioner, a leave-in, or any type of product.
