• K18 Hair Mask PEPTIDE™ 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

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 K18 Hair Mask PEPTIDE™ works on a molecular level (where all hair is the same), this product is effective on all hair types

how to optimize k18

• 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
