It has been said that stress can make you go gray, or cause you to lose your hair. Is that possible?
Sometimes, you might feel like tearing your hair out due to personal, economic, and work-related stresses, but stress won't likely be the direct cause of gray hair. A 2009 study in the journal Cell found that unavoidable damage to the DNA in cells that produce the pigment responsible for hair color is most likely the culprit that causes a hair to turn white.
But can stress accelerate the aging process on a cellular level and, as a result, cause you to go gray before your time? Right now, the answer is debatable.
We have all witnessed the graying hair of many past presidents. Perhaps over long periods of stress, there may be an acceleration of gray hair in some people. But, that idea is mainly speculation.
If the jury's still out on the question of stress being responsible for turning hair gray, then what's the verdict on stress and hair loss? Is there a relationship?
It all depends on what type of stress you're talking about. Stress because you're late to work or you've got a heavy workload is not going to cause you to lose hair. That is short-term, everyday stress is not going to affect your body in such a way that your hair falls out. It takes something larger to do that. Something that causes you to lose sleep, or changes your appetite and raises the level of stress hormones.
Stress and Hair: The Hair Cycle
A normal head of hair contains about 120,000-150,000 strands of hair. Usually, at any one time, about 90% of those hairs are in a growing phase, growing by about 1/2 inch each month. This phase lasts for two to three years. At that point, a hair will go into a resting stage. This "rest" lasts for 3 to 4 months before the hair falls out and is replaced by a new one.
Typically, people shed about 100 hairs a day, most people don't even notice.
Sometimes, a significant stress of some sort may spark a change in your body's routine physiological functions, and cause a disproportionate number of hairs to go into the resting phase at the same time. Then three to four months later, sometimes longer, all those resting hairs are shed. The effect can be alarming. The types of events that disrupt the normal hair cycle, can be caused by the substantial physiological stresses on your body.
Physiological stress is not the same as emotional stress. Hair loss can be one way the body responds to significant physiological stress that may be brought on by diet, medical, or lifestyle changes.
Only those things that cause physiological stress can cause a hair loss event. The good news is that the hair loss from these kinds of events is usually only temporary, as long as the stress event is temporary. Once the stressor is addressed, or goes away on its own, hair grows back and the normal hair cycle resumes.
Stress and Hair: What Causes Hair Loss? A variety of stressors may cause your body to undergo hair loss. It happens, when there's some type of physiological change in your system. "For instance, you go on or off an oral contraceptive. Or you lose more than 15 pounds of weight. Things like this change the physiological balance in your system.
Other stressors could include:
Being on a strict low-calorie dietAfter childbirth when estrogen levels fallSevere illnessHaving a high feverHaving major surgerySevere infectionsHair shedding can also result from certain medications such as some type of blood pressure medications, thyroid disease, and nutritional deficiencies such as vitamin D or excess vitamin A.
Pinpointing the actual cause of the shedding isn't always easy. That's because, there's a three- to six-month lag time between the stressful event and the hair loss. In order to determine the cause, you need to look back at what was happening three, six, or even nine months before the hair loss began.
Stress and Hair: The Physiological & Emotional Connection If you're going through a very severe divorce, you might not be eating properly; you might lose weight or not sleep well. You may go off and then back on your oral contraceptives. All of these things cause physiological stress and an imbalance in your system. The point is, there are a lot of other things that are physiological going on. You're not losing your hair because you hate your ex-husband.
Women have a number of things that happen on a regular basis that they may not recognize as stressors. You start out your life and you're fine, You're 20 years old and get married. You get on some oral contraceptives. Well, that causes shedding.
When a woman decides to have a baby, if she is taking them, she will stop taking oral contraceptives. Maybe you have a little bit of shedding related to that. And then you get pregnant. Pregnancy causes the body to keep the hair that normally would fall out as part of the regular hair cycle, so a woman may notice her hair may feel extra thick and fuller during that time. After giving birth, all the hair that would have fallen out is shed three to six months later.
Also, after birth, you realize you've gained 30 pounds and go on a diet to lose it. That causes shedding. But somewhere in all this, someone in the family dies and, because you've heard that stress causes hair loss, you say, 'Oh my God, I'm losing my hair because someone died.' But that's not it. You're losing hair because you lost 30 pounds.
It's not a foregone conclusion, not everyone gets these episodes of hair loss. Some women go on and off of contraceptives and never have shedding. Some have seven children and have no hair loss related to it. Once you have shed hair in response to a physiological stress, you are likely to do it again.
People have repeated the myth of a direct connection between emotional stress and hair loss for so many years, many people now believe it. "There's no way to predict who's going to lose hair and who's not. If you're a shedder, you'll shed. There's no scientific evidence that points to specific emotional stresses that might trigger the physical stress that can lead to hair loss.
Seeing a Doctor About Hair Loss Unlike other types of hair loss that are more often permanent, hair loss during the normal hair growth cycle happens suddenly. It also doesn't normally cause bald spots, or follow a pattern like genetic or autoimmune-related hair loss. Instead, it's diffuse and causes thinning of the hair across the scalp. That’s because each of the 120,000-150,000 hair follicles is independent of other hair follicles, and is in its own cycle of growth -- some are growing while others fall out.
You may notice after washing your hair that handfuls of hair have fallen out. But, usually by the time someone notices the shedding, the hair is already growing back. Whatever caused it happened three months or more before. The new hair growing in is pushing the resting hair out.
That doesn't mean there's no reason to go to the doctor. Hair loss can be an early sign of about 30 different diseases. It's never too early to talk to a doctor about hair loss. The doctor can evaluate what's happening and help you understand it and know what to do. Products on the market, such as over-the-counter minoxidil and various supplements that are sold for hair loss, can actually cause problems if they're not truly needed and not used properly. It's important, to discuss the use with the doctor first.
A doctor can also help you identify the particular stressor that's causing the shedding. There may be lots of things going on that's causing it. A doctor can help you find them out and help you know how to address them. Once the causes of stress are addressed, the shedding should stop and your hair should return to normal.
