All About Dandruff
The itching and flakes associated with dandruff are a nuisance that can make you feel self-conscious. You can't prevent dandruff, but the proper use of over-the-counter shampoos usually relieves the symptoms.
The itchy scalp and white flakes of dandruff that you may have noticed on your sweaters and blouses are usually not a medical problem, but they can certainly be embarrassing. Dandruff, a mild form of a common skin condition called seborrheic dermatitis, appears when skin cells grow and die off too fast.
Contrary to what you may think, dandruff usually isn’t caused by careless hygiene. In some cases, dandruff results when a fungus that naturally lives on the scalp grows out of control. If dandruff flakes are yellowish and oily and the scalp is red, the cause may be another form of seborrheic dermatitis, one that’s called cradle cap when it occurs in infants. Hormonal changes and the onset of winter, with its cold, dry air, can make dandruff worse.
