Dandruff is the shedding of dead skin cells from the scalp (not to be confused with a dry scalp). Dandruff is sometimes caused by frequent exposure to extreme heat and cold. As it is normal for skin cells to die and flake off, a small amount of flaking is normal and common; about 487,000 cells/cm2 get released normally after detergent treatment. Some people, however, either chronically or as a result of certain triggers, experience an unusually large amount of flaking, up to 800,000/cm2, which can also be accompanied by redness and irritation. Most cases of dandruff can be easily treated with specialized shampoos.
Causes of Dandruff are:
- mal nutrition
- Lack of minerals like zinc and calcium in diet.
- Fungal infection especially malasezia furfur is the major cause of dandruff
- Infections caused by yeast
- Usage of soaps and shampoos those are alkaline in nature.
