Reducing stress in your life is a good goal, but it won't necessarily turn your hair to a normal color. The results were compared with each volunteer's stress diary, in which individuals were asked to review their calendars and rate each week's level of stress. 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.
How to deal with hair loss?
But the culprit ended up being a different part of the body’s fight or flight response — the sympathetic nervous system. 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. Gray gets a bad rep in a world that’s looking to biohack our way to forever, but a reputation is all it is — and that can be changed. You can rock your grays like a rock star, dye them to wait until more arrive, or even take a closer look at your diet for potential nutritional gaps — because the truth is grays aren’t an overnight occurrence. Stress is a normal reaction to everyday pressures, but it can become unhealthy when it upsets a person's day-to-day function, according to the American Psychological Association.

Picard and his team began searching for others with two-colored hairs through local ads, on social media and by word of mouth. Not at all, though if the gray hairs come in a short period, they may be a sign that you’re under too much stress. If that’s not the case, you could embrace your gray hair and enjoy celebrating your age. Not everyone showed evidence of regaining color, and it didn’t happen in any volunteers over the age of 40 in this study. More research will tell us if de-stressing can reverse hair loss later in life. 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.
Mice and humans are different. Often medical studies in animals turn out to be impossible to replicate in people.
They found that noradrenaline, also known as norepinephrine, was key to stress-induced hair graying. By injecting noradrenaline under the skin of unstressed mice, the researchers were able to cause melanocyte stem cell loss and hair graying. To connect stress with hair graying, the researchers started with a whole-body response and progressively zoomed in on individual organ systems, cell-to-cell interaction, and, eventually, all the way down to molecular dynamics. The process required a variety of research tools along the way, including methods of manipulating organs, nerves, and cell receptors. Hair growth demands lots of energy and while strands are growing, cells receive signals from the body, including stress hormones, the authors write. It’s possible these exposures trigger changes in hair pigmentation.
How Does Stress Affect Your Hair Color?
Infographic depicting how stem cells are depleted in response to stress, causing hair to turn gray in mice. Changes in 300 proteins occurred when hair color changed, and the researchers developed a mathematical model that suggests stress-induced changes in mitochondria may explain how stress turns hair gray. As they age, men tend to lose the hair on top of their head, which eventually leaves a horseshoe-shaped ring of hair around the sides. It's caused by genes from both parents – the idea that men take after their mother's father is a myth. It's fueled by dihydrotestosterone, a byproduct of the male hormone testosterone. In female-pattern baldness, the hair loss is different – it thins throughout the top of the scalp, leaving the hair in front intact.

Without stem cells left to create new pigment cells, new hair turns gray or white. Because stress affects the whole body, researchers first had to narrow down which specific systems were involved. The team first hypothesized that stress causes an immune attack on pigment-producing cells. However, when mice lacking immune cells still showed hair graying, researchers turned to the hormone cortisol. The mitochondria connection between stress and hair color differs from that discovered in a recent study of mice, which found that stress-induced graying was caused by an irreversible loss of stem cells in the hair follicle.
For some people, some of their hair can naturally go back to its original color.
With fewer stem cells to turn into pigment cells or melanocytes, less melanin can be produced. Using florescent labelling, the researchers observed the stem cells change to melanocytes and migrate away from their reserve in the hair follicle. With no remaining stem cells, no new pigment cells can be made, and any new hair becomes gray, then white. Although reducing your stress levels might seem insurmountable, making sure you’re eating the right things will go a long way to setting a good foundation for optimum hair growth. A healthy balanced diet is also important in stress reduction too as it can support a healthy immune system, repair damaged cells and even reduce elevated cortisol levels. 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.

Gray hair is really hair with reduced melanin, while white hair completely lacks it. That’s partly because of a gradual decline in the number of stem cells that mature to become melanin-producing cells. The cells may wear out, become damaged, or lose the support systems meant to keep them working. Genes are also a factor, since they help control melanin production.
After eliminating the immune system and the stress hormone cortisol as causes of the color change, the team discovered that part of the animals’ nervous system was depleting pigment cells from hair. Chemicals released during the stress response — specifically norepinephrine — causes pigment producing stem cells to activate prematurely, depleting the hair’s “reserves” of color. The researchers eventually turned to the neurotransmitter noradrenaline, which, along with corticosterone, was elevated in the stressed mice.
“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." 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.

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. Yet just about everyone – no matter what kind of hair they have – falls prey to at least one hair problem at some point in life. Scott recommends using a big barrel curling iron to create waves. If you prefer your hair up, Pacheco suggests crossed and french braids that will also help hide grays (or enhance the look with weaves of color).
