Dandruff

Dandruff is the shedding of dead skin cells from the scalp. Dandruff is not to be confused with a simple dry scalp. As skin cells die a small amount of flaking is normal; about 487,000 cells/cm2 get released normally after detergent treatment. 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. Most cases of dandruff can be easily treated with specialized shampoos. There is, however, no true cure.
