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.

Do gray hairs from stress go away?
Reverse graying is also more common in patients being treated for a hair loss condition, rather than people who are graying normally, he said. There's a long-held belief that graying hair is more than just an issue of time and age — it's a marker of lived experience. The adage, "you're making my hair gray" suggests silvering strands are a record of worries, while Marie Antoinette's hair went white in a single night after learning of her execution, according to legend.

If you’re dealing with hair loss from stress, take heart in knowing that it’s likely temporary and your hair should return to normal. 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. It's important to remember that going gray is a natural part of aging that everyone will likely go through eventually.

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. 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.
"Mitochondria are actually like little antennas inside the cell that respond to a number of different signals, including psychological stress." "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," Picard says.

That strand of hair — or in the mouse's case, fur — lost its source of color. Having established a link between stress and graying, the scientists then explored several potential causes. They first tested whether immune attack might be responsible for depleting melanocyte stem cells. But stressing mice with compromised immune systems still led to hair graying.
Exercise creates the release of “feel-good” chemicals like dopamine and serotonin. Mindfulness is the psychological process of actively paying attention to the present moment. But this emergency stress response isn’t always useful in our modern world of everyday stressors.
In response, corticosterone (rodents' equivalent of the stress hormone cortisol) and norepinephrine (a neurotransmitter and hormone) flooded into the follicle. Once in the follicle, the norepinephrine caused the stem cell to transform into a regular melanocyte, meaning it could not divide indefinitely. With the stem cell permanently changed, the follicle no longer had a source of new pigment cells.

Happily, “this type of hair loss is not permanent and generally resolves on its own within one to three months,” she says. Hill explains that the gray coloring of a hair fiber is a result of some melanocyte activity (the cells that produce melanin), and the white coloring of a hair fiber is the complete absence of all melanin and melanocyte activity. As we age, hair follicles naturally begin to produce less melanin.
If strands are about to go gray anyway — perhaps near middle age — a stressful event might push hair cells past that threshold earlier, the study noted. Then when the stress ends and the hair is just above the threshold, it could revert back to dark. "What we do has a material impact on things we used to think were irreversible like hair graying," Picard said. In practice, Kingsley said he doesn't often see hair recover its pigment.
Researchers found that under acute stress, hair in mice turns gray because an overactive sympathetic nervous system (“fight or flight”) can lead to the rapid depletion of melanocyte stem cells, the cells involved in creating pigment. According to researchers, stress causes the stress hormone norepinephrine to release into hair follicles. This caused a noticeable loss of melanocyte stem cells in mice. 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.
It’s possible these exposures trigger changes in hair pigmentation. Research shows that chronic stress can decrease stem cells that produce pigment of color in your hair. 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.
We often think that stress may also play a role, but until recently, that hadn't actually been demonstrated in humans; a 2021 study finally brought some evidence to the table. Some people start seeing gray hairs in their 20s; others in their 50s, so that window of opportunity will vary. Hair needs to reach a threshold before it turns gray, Picard said.
