In the meantime, experience the K18 Limited Edition Molecular Repair Mask x Future Society 50ml — the same molecular repair, elevated with a limited-edition scent.*

A leave-in treatment mask that works on the molecular level to reverse hair damage in just 4 minutes.

The K18PEPTIDE™ is clinically proven to repair damage from bleach + color, chemical services and heat - with immediate and lasting results to restore strength, softness, smoothness and bounce to hair.

  • Takes damage repair further - reconnects both polypeptide chains (and as a result, also reconnects disulfide bonds) for strength along the length + width of the hair - offering comprehensive, lasting damage repair
  • Restores hair from even extreme damage - by working at the innermost layer of the hair, core strength and elasticity are renewed for strong, smooth, bouncy hair
  • Delivers immediate and lasting results - hair is repaired from the first use and lasts past your next wash, for ongoing reparative benefits
  • Simplified repair - convenient, leave-in formula works in just 4 minutes, with no extra rinse required
  • Works on all hair types - because K18PEPTIDE™ works on a molecular level (where all hair is the same), this product is effective on all hair types

4-minute leave-in treatment to reverse hair damage

  • K18PEPTIDE™ is a biotech-developed peptide that mimics hair's structure to reverse damage by reconnecting polypeptide chains and disulfide bonds broken during bleaching, color and chemical services + heat.
  • pH-optimized (5.0-6.0): Helps minimize cuticle swelling + put hair proteins in their most resilient state
  • Cream format: Enables easy, lightweight application across all hair types, with detangling and softening benefits

Vegan, color-safe, cruelty-free

  1. How much of the K18 Leave-In Molecular Repair Hair Mask should I apply to my hair?
    For the longest and thickest or most curly-coily hair, you should start with up to 3 pumps of the 50ml K18 mask or 9 pumps of the 15ml K18 mask. You can add more if needed to cover any missed strands, but be careful not to overapply as it may weigh down your hair.
  2. How many applications can I get from each size of the K18 Leave-In Molecular Repair Hair Mask (5ml, 15ml, and 50ml)?
    The 5ml size is significantly smaller, so it might only provide a single treatment. The 15ml size, using 9 pumps per application, would give approximately 1-2 treatments. The 50ml size should provide at least 16 treatments.
