The most common cause of dandruff is seborrheic dermatitis, a mild scalp inflammation with excessive fatty secretions that usually starts as dry or greasy scaling of the skin, but may progress to yellow-red scaling bumps along the hairline, behind the ears, in the ear canals, on the eyebrows, on the bridge of the nose, in the folds around the nose, or on the breastbone. Don`t pick or your scratch scalp, as this will only exacerbate your condition.
When infants get dandruff, it is called cradle cap, which is a yeast problem. Many skin experts in Europe consider dandruff in adults to also be a yeast problem. In other words, dandruff is often an external symptom of an internal problem. Therefore, dandruff treatments can be similar to those for treating candidiasis.
