Begin by incorporating The Clean Dirt every second or third day, increasing or decreasing as you find the rhythm that suits your individual needs. A good guideline is to exfoliate as often as you shampoo, so I most often incorporate this into my morning ritual. This seems to be the most appropriate timing for me, and also allows me to indulge in the shower for the least mess (it's worth it, I promise!). I let the formula sit on my skin while I run conditioner through my hair and scrub my body. It's the perfect amount of time, and when I rinse, massaging with my fingertips, both my hair and skin are silky smooth. Adjust to your preference - morning and night are equally wonderful.
