        Why skip conditioner?

        Conditioner leaves a flm 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 anytype 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 anagent to optimize the hair environment for the K18 Mask to work on a deeper level.

        When should l 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
