key benefits

leave-in molecular repair hair mask

  • Easy leave-in – simply shampoo, skip the conditioner, and apply to damp hair.
  • Powered by the patented K18PEPTIDE™, engineered over 10 years in a biotech lab to work on the molecular level to rebuild all hair types from the inside out in just 4 minutes.
  • Immediate + progressive results
  • Vegan, color-safe, cruelty-free


PEPTIDE PREP™ detox shampoo

  • Intentional active ingredients remove buildup without stripping
  • Removes 99% product buildup, 95% sebum + 76% copper with one wash *
  • pH 3.8-4.2 which helps maintain color and doesn’t dry out the hair
  • Color-safe, non-stripping lather creates a clean hair base for maximum K18 mask results.

how to use

  1. Cleanse with detox shampoo for the cleanest canvas. Do not condition.
  2. Towel-dry thoroughly.
  3. Begin with 3 pumps of K18 mask, only add more as needed depending on length, thickness, and condition. Apply all over, one pump at a time, maximum dosage is 9 pumps.
  4. Let sit for 4 minutes. Do not rinse out.
  5. Then comb + style as usual (fine to add heat protectant or styling product now).
  6. Use for the first 4-6 washes, then as needed.

how to optimize K18

  • DO use detox shampoo before the mask to remove buildup and help our peptide penetrate and get where it needs to go
  • 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 out the K18 mask

what you can expect
by damage type

backed by science,
loved by stylists

Our community of stylists and colorists believe K18 is liberating hair—no matter the hair type or generation.

“K18 allows me to go everywhere I want to go with my color work and the end result is my guests get to be bright and shiny and healthy.”

– Christine Thompson, Director of Color at Spoke & Weal

got questions?

Get started here

Will the detox shampoo dry my hair out?

A non-stripping lather works to unclog hair follicles while banishing dirt, oils, metals, and things left behind from heavy product buildup without stripping or leaving buildup behind (no fillers). In a consumer study, 90%* said hair feels clean without feeling dry. *results observed on 38 people after 10 days.

Will the detox shampoo strip color?

Nope! The PEPTIDE PREP™ shampoos are color-safe. This purposeful detox formulation is engineered to clean effectively without messing with your color.

why skip conditioner before the mask?

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

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

We like to keep our formulas minimal, only using the exact ingredients needed to get the peptide where it needs to go. Our 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 mask to work on a deeper level and give you the best results.

When should I expect to see mask results?

Most see results from the K18 mask after 2-3 uses. The more damaged the hair, the more dramatic the results so results may vary depending on your hair type + level of damage.

OMG

This stuff is gold period. I have curly extensions with naturally curly hair and this is the best stuff I've EVER used. I've used all of the products cheap, expensive, you name it. This stuff made my hair so soft and light and it tamed my frizz. It's expensive but it just takes a little. The stylist that does my extensions uses it as well. You have to try it!

It's magic!

I've never used a product that delivers everything that it promises. I could barely brush my hair after I washed it and conditioned it. With k-18 the snarls just fall out.

Disappointing

I spent a lot of money for this hair “miracle”. I didn’t notice any difference. Very disappointed.
