Next time you blame your coworkers, your friends, or your significant other for turning your hair gray, don’t look to science to back you up. So far, researchers have found no link between gray hair and stress, according to an October 24 article from the Scientific American. There are, however, plenty of unsubstantiated theories on why stress could turn you gray. It could damage hair cells, disrupting bodily signals, but the theories remain unproven. In the meantime, it’s probably best to blame your family, and their genetic coding, for all those silver tresses.–Bennett Gordon
