K18 Leave-In Molecular Repair Hair Mask is a 4-minute leave-in treatment to clinically reverse hair damage.

This at-home leave-in treatment is infused with the patented K18Peptide™ that works to repair even the most extreme damage, renewing hair to its most youthful, healthy state.

Traveling deeper into the inner layers of hair than traditional repair products, the revolutionary patented K18Peptide™ is just the right size and makeup to fit in and reconnect broken keratin chains, renewing hair with strength, softness, smoothness, and bounce. You can feel and see the difference from the first use.

Who's it for?

Suitable for all hair types.

1. Shampoo and rinse.
2. Do not use conditioner, towel dry hair thoroughly.
3. Apply Leave-In Molecular Repair Mask and wait 4 minutes.
4. Do not rinse out.
5. After 4 minutes, apply styling products if desired and dry/style as usual.

TIP: for best results, use for the first 4-6 consecutive washes, then every 3-4 washes as needed to maintain hair strength.

As self-described hair care ‘liberators’, K18’s ethos is all about supplying you with the tools you need to express your identity, try new trends and have fun with your mane — without sacrificing the softness, strength and vitality of your hair.

By understanding the biology of your hair the K18 team has been able to get to the (*ahem*) root of the problem of hair damage, and — crucially — discover one hero bioactive peptide that will return strands back to their most healthy state.

Enter: the K18Peptide, a patented molecule that travels to the polypeptide chains (that’s the very innermost layer of your hair) where it repairs broken bonds and restores hair’s strength and elasticity. This is where biotech meets hair care!
