What Causes Dandruff?
Is your scalp itchy? Is it dry and flaky yet still paradoxically greasy? Do you shed a blizzard of flakes? Redness and tenderness to the scalp got you down? You very well may have dandruff or seborrheic dermatitis as dermatologist like to call it.
So why do some people get dandruff? The cause of dandruff is believed to be a complicated interaction between naturally occurring yeast, your skin oil, and the resultant inflammation. For unclear reasons, the yeast finds the composition of some individuals’ scalp oil to be delicious. The digestion of these oils generates fatty acids that penetrate the skin and stir up inflammation (hence the redness and flaking). It is not an infection of yeast per se, but a poorly understood reaction to your skin’s natural inhabitants.
