New findings suggest how stress may trigger gray hair Harvard Gazette

But again, this is really a moving target right now and each new piece of data changes things. When you are stressed, your body responds by releasing the neurotransmitter, noradrenaline as part of your “fight-or-flight" reaction. Under normal circumstances, pigment-producing stem cells remain inactive until new hair growth occurs. To begin building a new hair, the follicle factory must be rebuilt. Fresh keratinocytes and melanocytes are recruited from progenitor cells, also called "stem cells," residing at the bottom of the follicle. For unknown reasons, keratinocyte stem cells have a much greater longevity than the melanocyte stem cells, says David Fisher, professor of pediatrics at Harvard Medical School. "It's the gradual depletion of [melanocyte] stem cells that leads to the loss of pigment," he says.

What are common types of hair loss?

If you are one of those people who don't find gray hair distinguished, you can easily cover your gray with one of the many different hair dyes available. 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. What we know at the moment is that this outbreak is centred in a city in southern China called Wuhan. So, people are really on guard for another SARS-like outbreak that spreads all over the world, kills hundreds of people and has a high death rate.

So, we certainly need it, but it is not all we need, of course. Live Science is part of Future US Inc, an international media group and leading digital publisher. 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.

Tips for Preventing Premature Grey Hair

As for vitamins and minerals you can take, Garshick says studies show that biotin, calcium pantothenate, zinc, copper, and selenium may help with pre-mature graying. King points to products such as Arey that contain palmitoyl tetrapeptide 20, which have been shown in small studies to promote hair pigmentation. "Our data add to a growing body of evidence demonstrating that human aging is not a linear, fixed biological process but may, at least in part, be halted or even temporarily reversed." Some people start seeing gray hairs in their 20s; others in their 50s, so that window of opportunity will vary. “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.

I mean gritty determination because, frankly, we don’t have any other option. The fallout from atom bombs could be used to put an end to counterfeit whisky scams. Vintage whisky is big business, with one bottle fetching over US$1 million in 2018.

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. Using florescent labelling, the researchers observed the stem cells change to melanocytes and migrate away from their reserve in the hair follicle.

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. But no product based on the research is currently available. While scientists have made the link between stress and gray hair in mice, it's never been conclusively proven to happen in humans.

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. 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.

However you feel about it, gray or white hair is pretty much inevitable with age (if you're fortunate enough to still have hair in your later years). 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.

If you notice your hair is greying significantly without any major changes in your lifestyle or routine, please consult with your doctor to rule out potential medical issues. In short, scientists are beginning to gather clues that stress can hasten the graying process, but there is no scientific evidence demonstrating a cause-and-effect relationship. That stress is prompted by an imbalance between free radicals and antioxidants in your body that can damage tissue, proteins, and DNA, Kasey Nichols, NMD, an Arizona physician and a health expert at Rave Reviews, told Healthline.

You can see a similar dramatic change in former President Clinton. All recent Presidents have visibly aged while in the Oval Office more than you’d expect from the passage of time. Might that also mean someday halting and reverting the march of premature gray hair? “We would expect increasing gray hair as we advance in age, and we see about a 10 percent increase in the chance of developing gray hair for every decade after age 30,” Nichols 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. For every person who embraces his or her gray hair, many more curse this very visible sign of aging.

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. "The cortisol causes the melanocytes to replicate more rapidly into pigment cells, permanently killing off all the melanin-producing cells from the dermal papilla, creating a white or gray hair fiber formation," Hill says. However, noradrenaline activates these stem cells too early and causes them to move away from the hair follicle’s color reserves.

As we age, hair follicles naturally begin to produce less melanin. This makes the hair grow translucent, without any pigment, appearing white. Without the stem cells, there was no way to replenish the pigment-producing cells, and so the mice started to grey. Ya-Chieh wanted to work out exactly how stress triggers the loss of these stem cells. There have been theories that the immune system plays a role in stress-related hair greying, but Ya-Chieh showed that immunocompromised mice still went grey when injected with RTX, so their search for a culprit continued. In mice, stress can deplete hair-pigmenting cells known as melanocytes, according to a 2020 study in the journal Nature.
