K18 Leave in Molecular Repair Hair Mask is a professional leave-in treatment mask that works on the molecular level to reverse hair damage in just 4 minutes. Powered by the K18PEPTIDE™, clinically proven to repair damage caused from bleach + colour, chemical services and heat* – delivering immediate and lasting results that restore strength, softness, smoothness and bounce. This formula is vegan, colour-safe, cruelty free and suitable for all hair types.
What is K18PEPTIDE™?
K18PEPTIDE™ is a biotech-developed peptide that mimics hair's structure to reverse damage by reconnecting polypeptide chains and disulfide bonds broken during bleaching, color and chemical services + heat*.
Key benefits:
Deeper damage repair – 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.
Immediate and lasting results – hair is repaired from the first use and lasts past your next wash, for ongoing reparative benefits.
No rinse, leave-in convenience - convenient, leave-in formula works in just 4 minutes, with no extra rinse required.
Effective on all hair types – because K18PEPTIDE™ targets on a molecular level (where all hair is the same), it works for straight, wavy, curly, coily, fine, thick, or chemically-treated hair.
What to do - and what to avoid
Do:
- Clarify before K18 if you’re a heavy product user (demineralize for mineral + metal buildup).
- Apply on clean, damp hair.
- Wait the full 4 minutes before combing or styling.
- Add whatever styling products you love after the 4 minutes.
- 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).
- Overdo it—less is more.
- Rinse it out.
How to use the K18 Hair Mask: Shampoo, do not condition. Towel-dry thoroughly. Apply 1-3 pumps depending 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.
Pro Tip: For the most visible transformation, use K18 for the first 4–6 washes in a row. Then, switch to every 3–4 washes to maintain strong, healthy hair.
