It’s True, Stress Can Turn Your Hair Gray—and Now Scientists Know Why
The study, published in Nature, first recognized how stress affects the whole body (which it does in ways you probably never even thought of). That means that researchers needed to target which body system was responsible for connecting stress to hair color. After some trial and error (the stress hormone cortisol was cleared of all charges), a culprit was found: the sympathetic nerve system, the body's fight-or-flight response.
Sympathetic nerves branch out into hair follicles, experiencing stress causes nerves to release the chemical norepinephrine. Why does that matter? Because norepinephrine causes certain stem cells to convert into pigment-producing cells, which prematurely depletes a reservoir of color in a hair follicle. And there you are, a beautiful 29-year-old streaked with gray.
The wildest part is you're not just going to have a rough day at the office, get a skunk streak, and have it recover. Once you get white hair from stress, there is no manifesting your natural color back into existence. Sorry, babe.
"When we started to study this, I expected that stress was bad for the body—but the detrimental impact of stress that we discovered was beyond what I imagined," said the paper's senior author Ya-Chieh Hsu, PhD. "After just a few days, all of the pigment-regenerating stem cells were lost. Once they're gone, you can't regenerate pigment anymore. The damage is permanent."
All drama aside, this doesn't need to be a bigtime bummer! Think about all the amazing gray-haired icons out there! Andy Warhol! George Clooney! Miranda Priestly! Roger Sterling from Mad Men! MARIE ANTOINETTE. Yes, many of those examples have utilized wigs/are fictional. Nonetheless, you're in good company, you elegant, stressed-out silver fox. Likewise, totally fine if you want to get friendly with a colorist and cover up those bad boys, too.
Ultimately, the color of your hair matters less than than a brain on the fast track to burnout. So the next time you're feeling overwhelmed, close your eyes, take a whiff of some lavender essential oil, and think of France. It could always be worse.
