When you think about it - dandruff is very similar to EC, rapis shedding of the skin
Dandruff[1] is the shedding of dead skin cells from the scalp. As skin cells die a small amount of flaking is normal; about 487,000 cells/cm2 get released normally after detergent treatment.[2] Some people, however, experience an unusually large amount of flaking either chronically or as a result of certain triggers, up to 800,000 cells/cm2, which can also be accompanied by redness and irritation.
