    how to use

    For stylist use with a color or chemical service

    Begin with pro chelating hair complex:

    1. Section dry hair into 4 quadrants.
    2. Apply 6-10 sprays of K18 pro chelating hair complex per quadrant*.
    3. Wait 4 minutes after chelating** (do not rinse out)

    Apply the PRO molecular repair hair mist:

    1. Apply a minimum of 10 full sprays of K18 professional molecular repair hair mist to each quadrant, increasing up to 20 sprays per quadrant as needed, depending on client’s length, density, and level of damage.
    2. Wait 4 minutes (do not rinse out).
    3. If needed, dry the hair prior to applying lightener or color. Then perform your desired technique.
    4. Process your lightener or color as usual, then rinse and shampoo with K18 PEPTIDE PREP™ detox shampoo. Do not condition.

    Finish with the PRO molecular repair hair mask:

    1. Apply 1-3 pumps of K18 professional molecular repair hair mask based on your client’s length and density, starting at the ends and working up towards the roots.
    2. Wait 4 minutes (do not rinse), then proceed with cut or style as usual.

    *For cases of extreme metal + mineral buildup, process up to 10 minutes, then proceed with the instructions.

    **For best results, we recommend to use K18 chelator before every service. If not using K18 chelator, lightly dampen hair with water (do not saturate) before applying K18 PRO mist

      got questions?

      Get started here

      How can I tell if my clients need a chelating treatment?

      Every client needs a chelating treatment, because chances are high that they have some level of mineral + metal buildup. Regardless of your client’s hair condition, water quality, lifestyle, or desired services, they can benefit from a chelating treatment. Look for signs of buildup like visibly dull, discolored, rough, damaged-looking hair. Other signs are if their products aren’t working well, or after exposure to pool or ocean water.

      What metals does the PRO chelating hair complex target?

      The PRO chelating hair complex targets 7 of the most common metals and minerals from the hair: calcium, magnesium, copper, zinc, nickel, cadmium, and lead.

      Will the PRO chelating hair complex strip my client’s color?

      No, it will not strip your client’s color. This formula was engineered for more vibrant, even color application, and to revive existing discoloration or brassy color that can be impacted by mineral + metal reactions.

      Will K18 molecular repair service work on hair with a lot of buildup?

      Any type of coating whether it’s product buildup, sebum/oil buildup, or even mineral + metal buildup from hard water can block our biomimetic K18PEPTIDE™ from getting where it needs to go. We recommend using the PEPTIDE PREP® PRO chelating hair complex and detox shampoo prior to K18 PRO mist + mask application for first time users. It’s also great for people that use a lot of styling products as it clears the path for our peptide to fully penetrate hair.

      Is K18PEPTIDE™ considered a protein?

      K18 PRO mist + mask are not protein treatments, our biomimetic peptide naturally mimics the amino acid sequences in keratin to rebuild bonds broken by chemical, color, and heat damage. If your clients are experiencing dry, brittle hair, use PEPTIDE PREP® PRO chelating hair complex and detox shampoo to remove buildup prior to the K18 molecular repair service.

      The cutest tiny packaging

      I got this and I’m now offering haircuts/k18 treatments and people LOVE the results. Bonus I gave the first 5 clients when I first advertised a mini k18 mask!
