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

Groundbreaking PRO stylists, scientists + beauty experts have unlocked new levels of expression with K18 molecular repair.

got questions?

Get started here.

how does the k18 mask work?

K18 works as a treatment to reverse damage in 4 minutes. How it works is a lot like makeup vs. skincare. Concealers (i.e. most hair products) temporarily cover up a problem. K18 works like retinol, highly concentrated, working on a deeper level to renew that base health so you can wear less concealer in the future. Pretty cool right?

what is the k18peptide™?

Our biomimetic peptide mimics hair’s natural structure to seamlessly fit in and reconnect broken keratin chains responsible for hairs core strength and elasticity. As a result of this reconnection it also addresses cleaved disulfide bonds for connection along the Y-axis of hair AND the x-axis or width of hair.

why skip conditioner?

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 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 results?

Most see results 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.

IF YOU’RE TIRED OF FRIZZ

If you’re tire of frizz this is the product for you!!! Apply this liberally on clean , wet towel dried hair, and blow dry and frizz is no more. I love it and have been using for two years.

Repair

Well I've only used it once since I could only afford the mini. The result I had with it was good it seemed to condition without heavy weigh down. I plan on using all of the contents of the mini with hopes of seeing some good results on my hair.
