This product is part of the K18 PRO service and is designed to be used after damage caused during bleaching, chemical services, and heat styling. It's a leave-in treatment mask that helps repair and restore damaged hair, maintaining its strength and elasticity. The key ingredient is the K18PEPTIDE™, which works at the innermost layer of hair to reconnect broken polypeptide chains and disulfide bonds, effectively renewing core strength and elasticity in just 4 minutes.

Key Features:

  • The K18PEPTIDE™ technology targets the innermost layer of hair to address and repair damage caused by bleach, color, chemical services, and heat, resulting in stronger, smoother, and bouncier hair.
  • This product is suitable for all hair types.
  • It is clinically proven to reverse damage from various sources, including bleach, color, chemical services, and heat.
  • It restores strength, softness, smoothness, and bounce to the hair.
  • Provides both immediate and progressive results.
  • The formula is vegan, color-safe, and cruelty-free.

Through the K18 PRO Service (which includes the PRO mist and PRO mask), hair can be restored to up to 91% of its original strength and 94% of its original elasticity, based on clinical study results conducted during a bleaching treatment. Please note that results may vary depending on hair type, quality, and history.
