        bouncy results that won’t wash away.

      how to use molecular repair mask

      1. Shampoo, do not condition. Towel-dry thoroughly.

      2. Apply 1-3 pumps based on your length and density, starting at the ends and working up towards the roots.

      3. Let sit for 4 minutes. Do not rinse out.

      4. Comb, add styling product + style as usual. Use for 4-6 washes, then as needed.

      key benefits

      Takes damage repair further–

      reconnects both polypeptide chains (and as a result, also reconnects disulfide bonds) for strength along the length + width of the hair - offering comprehensive, lasting damage repair.

      Restores hair from even extreme damage-

      by working at the innermost layer of the hair, core strength and elasticity are renewed for strong, smooth, bouncy hair.

      Delivers immediate and lasting results–

      hair is repaired from the first use and lasts past your next wash, for ongoing reparative benefits.

      Simplified repair-

      convenient, leave-in formula works in just 4 minutes, with no extra rinse required.

      Works on all hair types–

      becauseK18PEPTIDE™works on a molecular level (where all hair is the same), this product is effective on all hair types.

        how does the k18 mask work?

        The K18 mask works as a treatment to reverse damage in 4 minutes. It’s powered by our biomimeticK18PEPTIDE™to seamlessly fit in and reconnect 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, and progressive repair.

        what is the k18peptide™?

        K18PEPTIDE™is a biotech-developed peptide that mimics hair’s structure to reverse damage by reconnecting polypeptide chains and disulfide bonds broken during damage from bleach + color, chemical services, and heat*

        why skip conditioner?

        Conditioner leaves a film 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 product.

        i noticed there’s alcohol in the formula, isn’t that bad for you?

        We like to keep our formulas minimal, only using the exact amount of ingredients needed to get the peptide where it needs to go. Here the alcohol serves as an agent to optimize the hair environment for the K18 mask to work on a deeper level. Our unique blend of 3 alcohols functions to open the hair cuticle so theK18PEPTIDE™can penetrate the innermost layer of hair, reaching the broken polypeptide chains (keratin chains).

        when should i expect to see results?

        Most see results after 2-3 uses. The more damaged the hair, the more dramatic the results so it may vary depending on your hair type and level of damage.
