The K18PEPTIDE™ works at the innermost layer of hair, reconnecting polypeptide chains and disulfide bonds broken during bleaching, chemical services, and through heat damage. By addressing these damage sites at the innermost layer of hair, core strength and elasticity are renewed for strong, smooth, bouncy hair—even after the most extreme damage done in the salon.

pH level of 5.0-6.0 helps close down the cuticle to seal in the K18PEPTIDE™ for lasting strength + elasticity.

Damage is ongoing

Send the K18 retail sizes home with your client to maintain hair strength and elasticity in between salon appointments with at-home molecular repair.

• Powered by the patented K18PEPTIDE™, engineered over 10 years in a biotech lab to work on the molecular level to rebuild hair from the inside out in just 4 minutes.

• Clinically proven to reverse hair damage from: Bleach + Color, Chemical Services, Heat

*Results observed in a clinical study while using mist and mask as part of a bleaching treatment. Results may vary depending on hair type, quality, and history.

1. Shampoo, do not condition.
2. Towel-dry thoroughly.
3. Begin with 1 pump of K18 PRO 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, maximum dosage is 3 pumps.
4. Let sit for 4 minutes. Do not rinse out.
5. Style as usual.
6. If cutting, you may start right away. If toning, use K18 PRO mask first, then apply toner directly over top. Process as usual. Rinse or shampoo toner + reapply K18 PRO mask per instructions above.

• 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
