  4. Wait 4 minutes. Do not rinse out.
  5. Then comb, add styling product + style as usual.

  • Leave-in treatment mask for all hair types reverses damage in 4 minutes. Helps maintain your client's hair strength and elasticity in-between appointments.

  • Patented K18PEPTIDE™ technology works to repair damage from lightener* + color*, chemical services*, and heat**—restoring strength, softness, smoothness, and bounce to hair.


*Disclaimers

  • DO use a clarifying shampoo if you’re a heavy product or dry shampoo user to remove buildup and help our peptide penetrate and get where it needs to go.
  • DO wait the full 4 minutes before styling or applying other product
  • DO use every 4-6 shampoos consecutively to see and feel ongoing results
  • DON’T condition your hair before application (trust us, most won’t need it after K18, if you still need, add a leave-in after the 4-minute window is up post-application)
  • DON’T overuse, a little goes a long way.
  • DON’T rinse out. This is a leave-in, so you know, leave it in!

One use of leave-in molecular repair hair mask delivers:

  • Healthier hair in 4 minutes*

Get started here
K18 is engineered to work with every hair type, in every service, and with every routine.
Traditional conditioners leave a film on hair that blocks our peptide from penetrating effectively. Once the 4-minute wait time is up, feel free to use a conditioner, a leave-in, or any type of styling product.
Water in damp hair swells the cuticle (the outside layer of hair) to open the gates for our biomimetic peptide to enter and travel to the innermost layers of hair. If the gates aren’t open, the product will stay on the surface—giving you mostly superficial repair. By applying on damp hair, you can use less, waste less, and still get the best results.
Think of the K18 mask as a highly concentrated treatment. It restores hair’s strength + elasticity in the innermost layers of hair, instead of traditional conditioners that coat the outside of hair. After the 4-minute wait time post-K18 mask, feel free to add a leave-in for a boost of conditioning if needed.
Yes, both formulas are the same. The PRO mask is conveniently sized for PRO use.

    The best restorative medicine for hair! The leave in mask

    I’m in love with the line K18 , as a professional hair stylist I’ve tried many different types of treatments and this one for me is a winner! I’m all about theory /certification to really understand the main core principles/use of a product.

    Hair feels silky, clean and healthy! Highly recommend K18 to keep that crown shiny.
