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 7.5-8.0 shifts the cuticle layer open to deliver the K18PEPTIDE™ to damage sites on the molecular level.

• In cases of extreme damage or certain salon services, the mist works alone to renew hair without weighing it down.

• 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.

• Because the K18PEPTIDE™ works at the molecular level, it works on every single hair type

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

• Restores strength, softness, smoothness, and bounce

• Immediate + progressive results

• Vegan, color-safe, cruelty-free

With just one salon treatment using the K18 PRO service (PRO mist + PRO mask), hair is restored up to:

91% original strength*
94% original elasticity*

*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.
