Scientists Finally Pin Down Why Stress Turns Our Hair Gray

It's a well-burnished saying: Stress makes your hair turn gray. But is there actually a correlation between stress and losing the natural color of your locks?

According to a study published today in Nature, there is, in fact, a direct link between stress and graying. Over the past two decades, researchers have found preliminary evidence that stress plays at least a small role in initiating the graying process. But our understanding of how that works has been murky - until now.

It hinges on melanocytes, pigment-making cells that give our hair its color. Scientists knew losing these cells in hair follicles robs hair of its luster, but they had yet to pin down the mechanism responsible for triggering the depletion of melanocytes. Now, scientists finally have an answer: the fight-or-flight response.
