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 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.

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.

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*.
pH-optimized (5.0-6.0) to help minimize cuticle swelling + put hair proteins in their most resilient state.
Cream format enables easy, lightweight application across all hair types, with detangling and softening benefits.
Vegan, color-safe, cruelty-free.
