    • more to know

      Takes damage repair further – biomimetic peptide seamlessly fits in and reconnects broken polypeptide chains at the molecular level. As a result, disulfide bonds are also reconnected for reinforced strength along the length + width of hair—offering comprehensive, lasting repair.

      Renews hair for better in-salon results - restores chemically damaged hair and makes hair more resilient for optimal salon transformations. Use before services for a stronger foundation and to help prevent damage during services.

      Resets hair’s strength and elasticity – allowing you to push transformations further with confidence.

      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.

    • key benefits
      • Fortifies hair pre-service to restore up to 99% elasticity*
      • Improves hair’s resilience to prevent damage during and after services for stronger hair over time
      • Color lasts longer + fades slower* when paired with K18 mask usage at home
      • pH level 7.5-8.0 helps the K18PEPTIDE™ better access the hair fiber's core, delivering lasting repair to the innermost layers
      • Made without emollients, the PRO mist won’t interfere with chemical and color services

who is it for?

K18 is engineered to work with every hair type, in every service, and with every routine.

why is the pro mist used before chemical services?

K18 PRO mist is used before chemical services to reverse existing damage and fortify hair pre-service, restoring up to 99% elasticity*. Use before services for a stronger foundation, and to help prevent new damage during services for optimal salon transformations.

By improving hair’s resilience, you can prevent damage during and after services* for stronger hair over time*, especially when paired with K18 mask usage at home. PRO mist empowers you to push your transformations further, and enables your freedom of expression.



*Disclaimers

why do i mist hair with water before using the pro mist?

You should start by misting hair lightly with water before using the PRO mist - to swell the cuticle layers and open up the hair fiber, allowing for maximum penetration of the peptide-powered PRO mist into the innermost layers of hair. In the same way a damp sponge absorbs more water, damp hair absorbs K18PEPTIDE™.

how much pro mist do i use?

Apply a minimum of 10 full sprays of K18 PRO mist per quadrant, increasing up to 20 sprays as needed, depending on client’s length, density, and level of damage.

do i need both pro mist + mask?

The PRO mist + mask (K18REPAIR™ service) were engineered with specific formats and pH ranges for optimized use throughout your services. Use the PRO mist to reverse existing damage pre-service and help prevent new damage during services. Use the PRO mask to reverse damage from bleach* + color*, chemical services*, and heat* after salon services. K18 molecular repair allows you to push transformations further with confidence, and realize your vision on stronger, more resilient hair.
