        dos and don'ts

        DO clarify before K18 if you're a heavy product user (demineralize formineral + metal buildup).

        DO apply on clean, damp hair.

        DO wait the full 4 minutes before combing or styling.

        DO add whatever styling products you love after the 4 minutes.

        DO use for 4-6 shampoos consecutively for progressive results.

        DON'T use conditioner before applying K18 Mask (you can applyafter the 4 min but most find they don't need it).

        DON'T overdo it-less is more.

        DON'T rinse it out.
