Scientists Think They Know How Stress Causes Gray Hair

The scalp contains a natural oil called sebum, which helps keep the skin lubricated. Sometimes these glands work overtime and produce too much oil, leading to a greasy scalp. Greasy hair can look dull, limp, and lifeless, and it may be more difficult to manage. To treat greasy hair, try washing with a gentle shampoo that is specially formulated to control sebum.

We are at a critical time and supporting climate journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen environmental literacy and ensure that our response to climate change is informed by science. Gray hair has been linked to stress for centuries — think of U.S. presidents before and after holding office.

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. Managing stress is a healthy goal regardless of its effect on how you look. 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. She emphasizes that people have more control over stress and aging than they realize.

The style and color of our hair can alter our physical appearance and affect our body image. Graying hair is perceived as a sign of old age, which can affect a person’s self-esteem, especially if it occurs prematurely. In short, yes, stress can turn your hair gray — but not in the way you might think. Whether you're dealing with acute stress, chronic stress, or even psychological stress, there's a chance that it can be the cause of your graying hair. The researchers used mice to determine if stress could cause hair to turn grey.
How Stress Can Affect Hair Loss And What To Do About It
When our body responds to stress, it often damages healthy cells. In one study, researchers found that, in mice, the response to stress damages DNA which accumulates over time. Although another mouse study has shown a link, there isn’t any scientific evidence on humans that illustrates a direct correlation between stress and gray hair. The team ultimately discovered that signaling from the sympathetic nervous system plays a critical role in stress-induced graying. Sympathetic nerves extend into each hair follicle and release noradrenaline in response to stress. Normally, the melanocyte stem cells in the follicle are dormant until a new hair is grown.
Facts That Will Change Everything You Think About Going Gray
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.

How to keep your cells young:
Extremely unlikely, scientists say, but stress may play a role in a more gradual graying process. Unless you dye, your hair eventually loses its color, usually beginning in your 30s or 40s. Though going gray is natural, many people dread it because of society’s notions about aging. Here’s what researchers know about how and why graying hair happens.

Consider the following coping strategies to help you relieve stress in your daily life. Marie Antoinette’s hair was said to have turned the color of snow overnight while she awaited the guillotine during the French Revolution. 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. Blow-drying, straightening, highlighting, and perming regularly can wreak havoc on hair, leaving it brittle, broken, and unmanageable.

All caused noticeable loss of melanocyte stem cells and hair graying. The color of your hair is determined by the amount of melanin in it. Pigment cells in your hair follicles called ‘melanocytes’ produce melanin. With fewer pigment cells, there is less melanin in the hair follicles. Eventually, your hair grows without melanin and it becomes grey and then white.
Exercise creates the release of “feel-good” chemicals like dopamine and serotonin. But this emergency stress response isn’t always useful in our modern world of everyday stressors. These physical changes come in handy when you need to react quickly in a life threatening situation. They helped our ancestors who needed a burst of energy to fight or flee predators, such as a saber-toothed tiger. “It was satisfying to question a popular assumption … [and] to identify the mechanisms that now open up new areas of work,” says Ya-Chieh Hsu, a stem cell biologist at Harvard University.
