The PRO mask is engineered to do cleanup duty after bleach + color, chemical services, and heat—restoring strength + elasticity to damaged strands. Lightweight conditioning benefits give your clients smooth, soft, strong, and bouncy hair, even after all the damage done in the salon.

Damage is ongoing

Send the K18 retail sizes home with your client to keep hair health going, make services last longer, and strengthen their canvas so you can go further during the next appointment.

• Do clarify before K18 if you’re a heavy product user (demineralize for hard water 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

1. Shampoo, do not condition.
2. Towel dry thoroughly.
3. Part hair into equal sections. Begin with 1 pump of K18 Mask and add more as needed depending on length, thickness, and condition. Work evenly into hair from ends to roots, one pump at a time.
4. Let sit for 4 minutes to activate. Do NOT rinse out.
5. Style as usual.
6. If cutting, you may start right away.
7. If toning, use K18 Mask then apply toner over K18 Mask. Process as usual. Rinse/shampoo toner, towel-dry thoroughly. Reapply K18 Mask as per instructions above. Style as usual.
