And research also shows that stress can speed up your body’s natural aging processes, including changes in hair color. These studies don’t show a direct cause-and-effect relationship. But they further support the link between stress and gray hair. In the study, researchers provoked a stress response in the mice.

Scientific American maintains a strict policy of editorial independence in reporting developments in science to our readers. The new Harvard research is only a mouse study, so replicating the same results in a human study would be necessary to strengthen the findings. It’s an important bodily function, but the long-term presence of heightened cortisol is linked to a host of negative health outcomes.

Podcast: How stress can cause grey hair, and the attitude needed to tackle climate change
The team’s first step was to identify proteins that show if a strand was gray, white, or colored—at any point in its history. She emphasizes that people have more control over stress and aging than they realize. “It's interesting to note that it is the perception of stress that is important. So if we feel we have the resources to handle the situation we're less likely to experience chronic stress." Managing stress is a healthy goal regardless of its effect on how you look.
Healthy Aging
Hair melanin comes in two shades—eumelanin (dark brown or black) and pheomelanin (yellow or red)—that combine in different proportions to create a vast array of human hair colors. Hair that has lost most of its melanin is gray; hair that has lost all of this pigment is white. The 14 healthy participants in this study were aged between 9 and 65, and already had some signs of gray or white in their hairs. It took the researchers two-and-a-half years to recruit them, which tells you that these findings don't necessarily apply to large parts of the population. Furthermore, it appears that once people are under less stress, the hair color can return – and while the researchers don't suggest that age-related grayness can be undone, these findings could teach us something about the biological processes of getting older.
They found that stressful experiences such as a job loss were linked to graying. While hairs are growing, cells receive chemical and electrical signals from inside the body, including stress hormones. These signals seem to change proteins under the roots, and those proteins harden once the hair grows out of the scalp. The researchers used mice to determine if stress could cause hair to turn grey. They had three groups, each exposed to a different level of stress. The study determined that noradrenaline (norepinephrine) was the reason for this occurrence.

Presumably the stress of impending decapitation caused her locks to lose color within hours. Extremely unlikely, scientists say, but stress may play a role in a more gradual graying process. Stress is more of a risk factor with hair loss than with going gray.
Scientists Think They Know How Stress Causes Gray Hair
This type of hair loss, known as telogen effluvium, occurs when someone undergoes stress on the body or mind. King explains that stress can cause a large number of hairs to become synchronized and fall out more than the normal amount that you're used to. The good news is, she says, that this kind of hair loss is reversible and does eventually grow back. "Our data show that graying is reversible in people, which implicates a different mechanism," says co-author Ralf Paus, PhD, professor of dermatology at the University of Miami Miller School of Medicine.
This article covers some of the most common hair dilemmas, from hair loss to greasy hair. It can be long and wavy, short and straight, frizzy and unmanageable, or smooth and shiny. Hair comes in many different lengths, styles, colors, and textures.
Research from 2020 suggests that graying hair is a permanent effect of stress. Once the melanocyte stem cells are lost, you can’t regenerate pigments anymore. However, Ya-Chieh and her colleagues showed that suppressing the stress-induced proliferation of the stem cells prevented hair greying. And they also showed that blocking the release of noradrenaline or chemically disabling the sympathetic nervous system meant that stress had no effect on the mice’s hair colour. Christopher Deppmann, from University of Virginia in the US, researches nervous system development and has written a News and Views article about the new work.
But stress isn’t the only — or even the primary — reason that most people get gray hair. "Based on our mathematical modeling, we think hair needs to reach a threshold before it turns gray," Picard says. "In middle age, when the hair is near that threshold because of biological age and other factors, stress will push it over the threshold and it transitions to gray.
The findings can help illuminate the broader effects of stress on various organs and tissues. This understanding will pave the way for new studies that seek to modify or block the damaging effects of stress. Harvard’s Office of Technology Development has filed a provisional patent application on the lab’s findings and is engaging prospective commercial partners who may be interested in clinical and cosmetic applications. Senior author Ya-Chieh Hsu shows off a diagram of a hair follicle — complete with a helpful test mouse. Stress can have a variety of negative effects on the body. The idea that acute stress can cause hair to turn gray is a popular belief.
Although aging is inevitable, it doesn't mean we can’t feel good about ourselves as the years go by. Taking care of our physical and mental health is something that will pay dividends in the long run. The first silvery strands usually pop up around age 30 for men and age 35 for women, but graying can begin as early as high school for some and as late as the 50s for others. That said, if you are going gray prematurely, it wouldn’t hurt to go have a checkup just in case natural genetic factors aren’t the sole culprit. And some degree of oxidative stress is a natural part of life.
