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*.

- 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
- Shampoo, do not condition. Towel-dry thoroughly
- 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
- Let sit for 4 minutes. Do not rinse out
- Comb, add product, and style as usual. Use for 4-6 washes post-salon service, then as needed
