more to know
  • K18PEPTIDE™ is a biotech-developed peptide that mimics the structure of hair to reverse damage by reconnecting polypeptide chains and disulfide bonds broken during bleaching, coloring, and chemical services + heat*.
  • pH-optimized (5.0-6.0) to minimize cuticle swelling and put hair proteins in their most resilient state
  • Cream format allows for easy, lightweight application across all hair types, providing detangling and softening benefits
  • Vegan, color-safe, cruelty-free
key benefits

Enhances damage repair – reconnects both polypeptide chains (and thus reconnects disulfide bonds) for strength throughout the length and width of the hair, offering comprehensive, lasting damage repair

Restores hair from extreme damage - by working at the innermost layer of the hair, core strength and elasticity are renewed for strong, smooth, bouncy hair

Provides immediate and lasting results – hair is repaired from the first use and continues to benefit beyond your next wash

Simplified repair - convenient, leave-in formula works in just 4 minutes, with no rinsing required

Effective on all hair types – because K18PEPTIDE™ works on a molecular level (where all hair is the same), this product is suitable for all hair types

how to use
  1. Shampoo, do not condition. Towel-dry thoroughly
  2. Apply 1-3 pumps of K18 leave-in molecular repair hair mask based on your hair length and density, starting at the ends and working up towards the roots
  3. Let sit for 4 minutes. Do not rinse out
  4. Comb, add product, and style as usual. Use for 4-6 washes post-salon service, then as needed
dos and don'ts

✔️ DO clarify before K18 if you’re a heavy product user (demineralize for mineral and metal buildup)
✔️ DO apply on clean, damp hair
✔️ DO wait the full 4 minutes before combing or styling
✔️ DO add your favorite styling products 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
