Dandruff isn't anything to be worried about in terms of health risks. It impacts men and women equally, with about 20 percent of the population experiencing symptoms at some point, and aside from negative impacts on your social life, it shouldn't cause too many problems. But a sudden, severe outbreak that comes out of nowhere and doesn't go away with over-the-counter treatment could be a sign of something more serious. "Dandruff itself does not cause other health risks, but interestingly, it can tend to come out more strongly in people suffering from chronic illness," says Dr. Krant. If shampoos, oysters and plenty of sleep aren't solving the problem, schedule an appointment.
