what makes it different

A leave-in treatment mask that works at the molecular level to reverse hair damage in just 4 minutes. Clinically proven K18PEPTIDE™ repairs damage from bleach, colour, chemical services, and heat, delivering immediate and lasting results for stronger, softer, smoother, and bouncier hair.*

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.

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 does the K18 leave-in repair molecular repair mask work?

The K18 molecular repair leave-in 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.

Why should I use the K18 molecular repair leave-in mask?

You should use the K18 mask because we put our hair through a lot. if you’re someone who expresses themselves through their routine, or frequents the salon for bleach, color, or other chemical services, K18 was engineered for you. If you just live your life with hair, you also need it, since just walking outside and exposing hair to sunlight or pollution can cause chemical reactions and damage. Think of K18 as that multivitamin for your hair, the first step in a healthier routine that makes all those other efforts go further.

got a question?

The cool thing about the K18 mask is it’s powered by our K18PEPTIDE™, which works on a molecular level (where all hair is the same) to renew all hair types. It’s also compatible with all products, easily fitting into any routine.

Less is more, so don’t overdo your K18 mask appllication. This highly concentrated formula was made to use way less than your traditional hair mask or conditioner. Start with 1 ml (1 pump of the 50ml mask, 3 pumps of the 15ml mask) and massage the product between your palms until the product thickens. Add more as needed, the maximum recommendation is 3ml (3 pumps of the 50ml mask, 9 pumps of the 15ml mask).

Yes, it is safe to use K18 mask after every wash on clean, towel-dried hair. Since it is a progressive treatment, you will see better results with continued use.

Think of K18 mask as a highly concentrated treatment. It restores hair’s strength + elasticity in the innermost layers of hair, instead of traditional conditioners that coat the outside of hair. Skip conditioner before applying the K18 mask so it has a clean canvas to penetrate into the innermost layers of hair. After the 4-minute wait time post-K18, feel free to add a leave-in for a boost of conditioning if needed.

Any type of coating whether it’s product buildup, sebum/oil buildup, or even mineral + metal buildup from hard water can block our biomimetic peptide from getting where it needs to go. We recommend PEPTIDE PREP™ detox shampoo prior to K18 mask application for first-time users, or people that use a lot of styling products. This will clear the path for our peptide to fully penetrate hair, and deliver maximum molecular repair results.
