more to know

The K18PEPTIDE™ works at the innermost layer of hair, reconnecting polypeptide chains and disulfide bonds broken during bleaching, chemical services, and through heat damage. By addressing these damage sites at the innermost layer of hair, core strength and elasticity are renewed for strong, smooth, bouncy hair—even after the most extreme damage done in the salon.

Damage is ongoing

Send the K18 retail sizes home with your client to maintain hair integrity in between appointments + the K18 PRO service.

how to use

  1. Shampoo, do not condition.
  2. Towel-dry thoroughly.
  3. Begin with 3 pumps of K18 leave-in molecular repair hair 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, add product + style as usual.
  6. Use for the first 4-6 washes, then as needed.

how to optimize K18

  • DO clarify before K18 if your client is 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
  • 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

pros using K18

how K18 works

Traveling into the innermost layers of hair, our K18PEPTIDE™ renews strength along the width AND length of hair for lasting strength where it matters.

got questions?

Get started here

how does the K18 mask work?

K18 mask 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 hair’s 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 your client the best results.

When should my client 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 client’s hair type + level of damage.

I absolutely love k18

I love the salon set, the only thing I wish was a better bottle to get all of the product out. Even when it’s empty there is still so much left in the bottle. That’s my only thing, other then that I love it so much!

Yes but…

While I absolutely love this mask and think the size is perfect for clients, there is product left in the tube when you think you’ve run out.

Possibly the engineering of the bottle itself.
