Clay masks have been used for skin clarification for thousands of years. As they have a bit of stickiness, clay masks squish down into skin nooks, crannies and pores, connecting with all the dirt and grime hiding in there. As the goo dries, it pulls away from your skin, and it pulls all of those impurities and dead skin cells with it. When you then wash off the dried up goo, you also wash away all that old oil, dirt, grime, etc. that was buried deep in your pores. These specially designed mask for hairy scalp skin have good amount of water in them so as they dry, your scalp skin is being hydrated and pores, now clean of junk, can close up, while blood vessels tend to open up a bit with this warmth, which means they do a much better job of bringing nutrients to your hair follicles and skin and removing toxins and impurities.
