Dandruff

I have been searching the internet and found an important thing that most of every one ever had this bad experience, ha..ha.. I also ever had this problem and now I have found out the reason.....this source I have read on times online...

Dandruff has been blamed on a multiplicity of causes, including dry skin, oily skin, too much or too little hair washing, diet, stress or hygiene. However, the real cause of dandruff is actually a yeast-like fungus, Malassezia globosa, which lives on your scalp, feeding on skin oils.
Dandruff is shedded skin; dandruff sufferers shed skin much more rapidly than other people. This happens because the fungus uses enzymes called lipases to metabolize the oils, which creates a by-product called oleic acid. The acid penetrates your skin and triggers skin cell shedding.
A team of researchers for Procter & Gamble (manufacturers of Head & Shoulders anti-dandruff shampoo) has sequenced the DNA of the fungus and analyzed the lipases it produces. They hope these investigations will eventually lead to new treatments for dandruff.
