Takes damage repair further – biomimetic peptide seamlessly fits in and reconnects broken polypeptide chains at the molecular level. As a result, disulfide bonds are also reconnected for reinforced strength along the length + width of hair—offering comprehensive, lasting repair

Restores hair after color and chemical services - 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 and with every service

• 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

• pH-optimized (5.0-6.0) to help minimize cuticle swelling + put hair proteins in their most resilient state after salon service or shampoo

• Cream format enables easy, lightweight application across all hair types, with detangling and softening benefits.

• Vegan, color-safe, cruelty-free

Just one application of the K18 molecular repair service (PRO mist + PRO mask) with a salon treatment brings your client’s hair back up to:

• 91% original strength*

• 94% original elasticity*

*Disclaimers

The K18 molecular repair PRO mask is meant to be used as the second part of the K18 molecular repair service.

• DO clarify before K18 if your client is a heavy product user (demineralize for mineral + metal buildup)
• DO apply on clean, damp hair (think about 65% wet)
• DO wait the full 4 minutes before combing or styling
• DO add whatever styling products you love after the 4 minutes

• 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
