K18 Professional Molecular Repair Hair Mask 5oz / 150ml

• K18PEPTIDE™ is a biotech-developed peptide that mimics hair's structure to reverse damage by reconnecting polypeptide chains and disulfide bonds broken during bleach, color and chemical services, and heat.
• 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

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

With a color or chemical service:

• Before the service, apply K18 professional molecular repair hair mist. Wait 4 minutes. Do not rinse out.
• Apply 1-3 pumps of K18 professional molecular repair hair mask based on your client’s length and density, starting at the ends and working up towards the roots. Let sit for 4 minutes. Do not rinse out.
• Proceed with cut or style as usual.
• If toning, use K18 PRO mist first, wait 4 minutes, then apply toner directly over PRO mist. Process as usual. Rinse or shampoo toner + apply K18 PRO mask per instructions above.

Without a chemical service:

• Shampoo, do not condition. Towel-dry thoroughly
• Apply 1-3 pumps of K18 professional molecular repair hair mask based on your client’s length and density, starting at the ends and working up towards the roots.
• Let sit for 4 minutes. Do not rinse out.
• Proceed with cut or style as usual.

• 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
