4-minute leave-in treatment to clinically reverse hair damage

A leave-in treatment mask for all hair types that clinically reverses damage in 4 minutes. The K18 peptide technology works to repair damage from bleach, color, chemical services & heat – restoring strength, softness, smoothness, and bounce to hair.


  • Powered by the 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

Directions:

  1. Shampoo, do not condition.
  2. Towel-dry thoroughly.
  3. 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, maximum dosage is 3 pumps.
  4. Let sit for 4 minutes. Do not rinse out.
  5. Then comb + style as usual (fine to add heat protectant or styling product now).
  6. Use for the first 4-6 washes, then as needed

Dos & Donts:

  • DO clarify before K18 if you’re a heavy product user (demineralize for mineral + metal buildup)
  • DO apply on clean, damp hair
  • DO wait the full 4 minutes before combing or styling
  • DO add whatever styling products you love after the 4 minutes
  • DO use for 4-6 shampoos consecutively for progressive results.
  • 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
