50 Million people in the U.S. alone suffer with Dandruff.
Dandruff causes excessive scaling on the scalp, with white flakes made up of dead skin cells.
There is no inflammation or redness and that is one of the differences between Dandruff and Seborrhea, or Seborrheic Dermatitis. Besides the terrible itching sensation, the appearance could be also embarrassing. Dandruff occurs mainly on the scalp. In most cases Dandruff is caused by excessive oil on the skin and scalp, not dryness as some people may think. Some cases of Dandruff and Seborrheic Dermatitis can be caused by bacteria or fungus like Pityrosporum Ovale or Pityrosporum Orbiculare.
