    more to know

    PEPTIDE PREP™ detox shampoo

    • A non-stripping, color-safe, pH-optimized lather works to unclog hair follicles while banishing dirt, oils, common metals like nickel, cadmium, lead, zinc, and iron from hard and tap water, and things left behind from heavy product buildup.
    • Intentional formulation means no fillers or deposits left behind leaving the cleanest canvas for maximum K18 molecular repair leave-in treatment results.

    leave-in molecular repair hair mask

    • A leave-in treatment mask for all hair types that reverses damage in 4 minutes. Helps to maintain your client's hair strength and elasticity in-between appointments.
    • Patented K18PEPTIDE™ technology works to repair damage from bleach* + color*, chemical services* and heat*—restoring strength, softness, smoothness, and bounce to hair.

    molecular repair hair oil

    how to use

    Begin with detox shampoo:

    1. Massage detox shampoo into hair + scalp to remove excess buildup.
    2. Thoroughly rinse.
    3. Repeat as needed.
    4. Wait to use conditioner until after the mask for optimal repair results.

    Apply the leave-in molecular repair hair mask:

    1. Towel-dry thoroughly.

    3. Apply all over, 1 pump at a time.

    Finish with the molecular repair hair oil:

    1. Apply 1-3 drops of molecular repair hair oil to damp hair, starting at the ends and working upward through the mid-lengths.
    2. Wait 4 minutes. Style as usual.
    3. Apply an additional 1-3 drops of molecular repair hair oil to dry hair as a finisher.
    4. A little goes a long way with our highly concentrated formulas. Start with the minimum recommended amount + build as needed.

      Get started here

      Is it better to recommend the full K18 routine?

      Yes, it is better to recommend the full K18 routine for your client’s cleanest, healthiest hair and optimal molecular repair results. Before the mask and oil, our PEPTIDE PREP™ category tackles every kind of buildup to create their cleanest, healthiest hair canvas. With our molecular repair formulas, they get maximum damage repair plus additional styling benefits with the oil. Your clients can use the K18 routine at home to keep their healthy hair going in-between appointments.

      Will the detox shampoo dry my client's hair out?

      No, the detox shampoo will not dry your client’s hair out. This non-stripping formula has a pH of 3.8-4.2 that won’t leave hair over-stripped. In a consumer study, 90%* said hair feels clean without feeling dry. *Disclaimers

      How do the molecular repair hair mask and oil work together?

      K18PEPTIDE™ in both formulas. The oil will add additional frizz-reducing, styling, and heat-protecting properties. You can layer the oil on top of the mask after the 4-minute processing time.

      Will the mask block the molecular repair hair oil from penetrating?

      No, the mask will not block the molecular repair hair oil from penetrating. The mask is a highly concentrated treatment without any fillers so it won’t block the oil from penetrating. Like layering different skincare products, the oil can be layered on top of the mask without impacting its performance.

      Is the K18PEPTIDE™ in every K18 product?

      K18 molecular repair + PEPTIDE PREP™ shampoos are formulated with the K18PEPTIDE™. In our molecular repair products, the peptide works at the innermost layers to reverse hair damage. In our PEPTIDE PREP™ shampoos, the peptide helps reduce protein loss to help keep hair feeling healthy and strong.
