The team then investigated the role of the stress hormone corticosterone, but altering its levels didn’t affect stress-related graying. Hair color is determined by cells called melanocytes, which produce the pigment melanin. New melanocytes are made from melanocyte stem cells that live within the hair follicle at the base of the hair strand. The hair that regrows from hair follicles that have lost melanocyte stem cells has less pigment and appears gray. The color of your hair is determined by the amount of melanin in it. Pigment cells in your hair follicles called ‘melanocytes’ produce melanin.
Are Grey and White Hairs Permanent?
Going gray is a part of the natural aging process for some, but can stress contribute to the early onset? To find out once and for all if there's a connection, we tapped some experts. Ahead, trichologists help us understand if stress can really make your hair turn gray or if there are other factors at play here. You’re more likely to go gray early if your family members also went gray prematurely. There’s some evidence that paternal genes — from the male side — influence when you go gray more than maternal genes (from the female side). So, if people on the male side side of the family had gray or white hair early, it’s more likely that you will go gray, too.

If you're noticing more grays accompanied by stress, making some life changes may be able to help. Researchers at Harvard University have found that stress can accelerate the graying process and have determined the biology behind the phenomenon — at least in laboratory mice. If you were an unruly child, you may have heard your parents say that you were “giving them gray hair.” You may have even heard stories about people’s hair turning white after experiencing a great shock.
How to Donate Your Hair to Support People With Hair Loss
Getting enough protein in your diet is essential as it provides the building blocks for proper hair growth; meat, tofu, eggs, beans, grains, nuts, and fish are all good protein sources. Some studies suggest that telogen effluvium can also be connected to low levels of iron, so include iron-rich foods like leafy vegetables, lentils and liver where you can. If you like the idea of adding supplements to your routine, there are some which are specifically formulated to contain ingredients that increase hair thickness and health. Spikes in cortisol can play a role in another kind of permanent hair loss, known as male and female pattern hair loss, says William Gaunitz. Gaunitz is a certified trichologist — a provider who specializes in hair disorders — and the founder of Advanced Trichology in Tempe, Arizona.
Researchers set out to determine if stress could also cause hair to gray, and if so, how. The study was funded in part by NIH’s National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) and other NIH components. 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.
What are the effects of stress on the body?
“Reversal of graying” — instances of hairs that had a white top segment, but were growing in darker at the bottom, or “repigmenting” — was discovered among 10 of the participants. "There was one individual who went on vacation, and five hairs on that person's head reverted back to dark during the vacation, synchronized in time," lead author Martin Picard, a neurologist at Columbia University said in a statement. “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.
On average, 85 percent of hairs are in the growth phase, while roughly 10 to 15 percent are in the telogen (or shedding) phase. When this natural cycle is disrupted, a larger percentage of the follicles transition to that shedding phase, Dr. Kuhn explains. Telltale signs can include seeing more hair in the shower or in your brush or noticing that your hair feels thinner.

After eliminating different possibilities, researchers honed in on the sympathetic nerve system, which is responsible for the body’s fight-or-flight response. “The stress response is necessary because it will promote survival in evolutionary terms. But there's a cost to being stressed and the cost is that maybe some of the cells age faster,” Picard said. He was amazed at the number of people who reached out to him to share stories of their white hair growing out in color.
Harvard Health Letter
The idea that acute stress can cause hair to turn gray is a popular belief. Hair lost to male-pattern and female-pattern baldness won't grow back on its own, but there are medications that can help slow hair loss and even regrow hair. Minoxidil (Rogaine) is a topical medicine that is available over the counter to treat men and women. Finasteride (Propecia) is a pill that is available to men only by prescription. Injectable cortisone may also help regrow hair lost to certain conditions. When hair loss is related to a medication, stopping the drug usually prevents further hair loss, and the hair will eventually grow back.
Looking at the proteins in the hair strands at different points allowed the team to see that some hairs that were now brown or another color had been gray or white earlier in the year. They also could match the changes in the proteins in the strands to the volunteers’ reports. “Just like tree rings hold information about past decades, and rocks hold information about past centuries, hairs hold information about past months and years,” they wrote. Other contributing factors to premature graying include deficiencies in protein, vitamin B-12, copper, and iron as well as aging due in part to an accumulation of oxidative stress.
The late Sen. John McCain, a Navy pilot during the Vietnam War, suffered multiple serious injuries when his plane crashed in North Vietnam and during beatings while a prisoner of war — and lost color in his hair. “But the hairs that have been gray for 30 years are probably unlikely to be reversible,” Picard noted. Deep breathing, mindfulness, and regular exercise are just a few ways to help manage stress. You may also consider talking with a mental health professional if you want additional support. If you find it difficult to cope or your stress symptoms don’t decrease, it may be time to talk with a professional.

At the end of the day, if the color of your hair is negatively affecting your self-confidence and how you feel about yourself, you may want to consider dyeing it. Genetics plays an important role in determining when your hair starts turning grey. Looking at how early it happened to your parents and/or grandparents is a good indicator of when it will happen to you. Low iron (anemia), auto-immune issues, or medication can also make your hair thin out.
Right now, there’s no way to stop or reverse gray hair, but researchers are investigating treatment options. One of the most-quoted research studies in this area showed that mice that experienced stress lost their fur pigment and went prematurely gray. Researchers exposed the mice to different types of stress, including mild pain and different forms of psychological stress. When there are no more pigment cells in a hair follicle, melanin cannot be produced and the effect is permanent. Scientists experimenting with mice recently showed that three specific genes can help maintain stable numbers of melanin-producing cells. By manipulating the genes, the researchers prevented or reduced gray hair in the mice.
