K18 Leave-In Molecular Repair Hair Mask
Results in one 4-minute use.
A leave-in treatment mask that works on the molecular level to reverse hair damage in just 4 minutes. The K18 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.
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 K18 works on a molecular level (where all hair is the same), this product is effective on all hair types
How to use
- Shampoo, do not condition. Towel-dry thoroughly
- Apply 1-3 pumps of K18 leave-in molecular repair hair mask based on your length and density, starting at the ends and working up towards the roots
- Let sit for 4 minutes. Do not rinse out
- Comb, add product + style as usual. Use for 4-6 washes post-salon service, then as needed
Do and Don't
✅ 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

Frequently Asked Questions
How does the k18 mask work?
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 K18 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.
Why skip conditioner?
Why 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.
I noticed there’s alcohol in the formula, isn’t that bad for you?
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 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 K18 can penetrate the innermost layer of hair, reaching the broken polypeptide chains (keratin chains).
When should i expect to see 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 it may vary depending on your hair type and level of damage.
Customer Reviews
My curl pattern came back after 5 weeks of using this product. I went to a hairstylist that used too much heat one time on my hair and have been struggling with heat damage for a year, slowly cutting it out.
Anywho I tried this product the detox shampoo, the leave in conditioner, and used ola….x bonding oil on the weekly basis to revert most of my hair.
There is this stubborn piece but I can hide that!
This makes my hair feel alive. I had my hair bleached. I looks beautiful and I love it but I knew I had to invest and k18 has definitely helped.
Recién llegado lo he usado dos veces, el cabello queda más liviano y con más sedosidad.
Po jednorazowym użyciu efektu wow nie ma. Włosy jednak układają się zdecydowanie lepiej niż bez użycia kosmetyków. Nie jest to coś sztucznego, mocno silikonowego z mnóstwem dodatkowych zapachów.
I can't believe I took so long to try this! My hair takes hours to dry and for some reason this makes it dry so much quicker and fuller. Tangible difference after only one use. AND it is so much quicker than a normal hair mask. I am thrilled with this.
