Don't Believe These Baldness Myths

BALDNESS MYTH 1: IT'S YOUR MOM'S FATHER'S FAULT

It used to be that if you wanted to know your chances of keeping your hair, you looked at your maternal grandpa. If that guy had strong hair game, you were in the clear. If he was bald, your fate was sealed. Turns out that's just not true. "It's totally a myth that you should look at your mom's father," says Joshua Zeichner, Director of Cosmetic and Clinical Research in Dermatology at Mount Sinai Hospital in NYC. Why? Because hair density is a polygenic trait, meaning more than one ancestor’s genes determine what’s going to happen. “Look at your parents,” says Zeichner, “and your siblings. If a family member is bald or showed early hair thinning, then you need to pay closer attention to your own hair and seek care from a board-certified dermatologist earlier rather than later."

BALDNESS MYTH 2: BALD GUYS HAVE MORE TESTOSTERONE

Long standing legend has it that bald guys are victims of their own elevated testosterone levels. They also have more active sex lives. They compulsively chop wood. And all that boiling testosterone cooks the hair off their heads. (They have great beards, though.) In fact, studies have shown that men who go bald and those who don’t have the same levels of testosterone. It’s more about how sensitive your hair follicles are to the influence of hormones in your body. And what determines that sensitivity? Genetics.

BALDNESS MYTH 3: TANNING WILL BAKE YOUR HAIR OFF

There are those who say lying out in the sun speeds up hair loss. While there’s plenty of bad news about UV radiation, it’s not exactly making you go bald. Follicle function will continue even when you’re playing beach volleyball. The concern here is that sun exposure can degrade the hair shaft itself. You know how a summer at surf camp can make your hair blonder? It can also make it more damaged and brittle, which could lead to shedding. Not the same as male pattern baldness, but maybe a reason to use conditioner. Or wear a hat.

BALDNESS MYTH 4: WEARING A HAT TOO MUCH SUFFOCATES YOUR HAIR

Speaking of hats, we all know that bald guy who always wears a baseball hat. So which came first? The hat, or the bald spot? Pop science says hats can suffocate hair and speed up the rate at which it disappears. Actual science says that’s baloney. "If you're wearing a really tight hat, maybe that can put pressure on areas where it contacts your head," says Zeichner, "which could potentially lead to traction alopecia." That's the medical name for hair loss triggered by pulling hair too tight. But don't worry. "Unless you are being really aggressive with the tightness, there's nothing to worry about," says Zeichner.

BALDNESS MYTH 5: STRESS IS MAKING YOUR HAIR FALL OUT

The final thing you don't need to worry about? Worrying. This one's a bit more complicated. True, certain traumatic events have been linked to hair loss—big stuff like suffering an illness, or going through a really tough time and losing or gaining a large amount of weight. But according to the Mayo Clinic, types of hair loss associated with high stress are telogen effluvium, a "resting phase" in which hair follicles pause, and alopecia areata, patchy hair loss. Both of which can be temporary. Neither of those is what we talk about as male pattern baldness. And neither is related to the everyday definition of "stress." So if you're fretting about your evil boss, or what your new line should be on Tinder, do so without fear. But also, you know, fix it. Because there’s no reason to tear your hair out.

What Hair Loss Really Means For Your Health

As a younger man, you noticed your hair thinning on top. Then a little bald spot popped up. Congratulations, you have male pattern baldness! About half of men do, although in some, it happens decades earlier than in others. (Many women have a similar condition—more about that later.) You know your thinning hair affects your appearance, maybe your self-esteem. But can it be a predictor of your health?

The Testosterone Link

Male pattern balding (MPB)’s medical name is androgenic alopecia. Androgens are “male” hormones, although women have them in smaller amounts, just as men have small amounts of estrogen. The most well-known androgen is testosterone. But a small portion of testosterone is converted into an even stronger androgen called dihydrotestosterone—DHT.
MPB is a genetic condition—it runs in families—marked by increased production of DHT. “Men with male pattern baldness produce higher levels of the enzyme that converts testosterone to DHT,” says Southern Illinois School of Medicine urology professor Kevin T. McVary, M.D., FACS. “DHT is the hormone that causes you to grow hair on your back—and lose it on your head. It also causes your prostate to grow.”

Benign Enlarged Prostate

Men who have male pattern baldness are more likely to experience symptoms of benign prostatic hyperplasia (BPH), aka enlarged prostate, says Dr. McVary. “In one Italian study, men with male pattern baldness were more likely to experience symptoms such as getting up at night, and urination urgency and frequency.” That’s why MPB is “potentially a way to identify men at risk for symptoms of BPH.”

If your pate is shiny, should you get checked? Not neccessarily. “Just because you’re bald doesn’t mean you need to see your doctor,” says Dr. McVary. “But if you have symptoms, bring it to your doctor’s attention.”
Of course, that’s good advice for every man, even those with lion’s manes.

Prostate Cancer

There is a link between getting bald early and getting prostate cancer. Several, but not all, studies show it. “Our study showed increased odds of prostate cancer with baldness by age 30,” says Charnita M. Zeigler-Johnson, Ph.D., an epidemiologist at the Perelman School of Medicine at the University of Pennsylvania. Men getting bald in the front by age 30 were more likely to get “clinically significant” prostate cancer before age 60, she found. Another study found the frontal link, but others have found a link with hair thinning in the middle of your head or vertex (the bald spot). While the cause isn’t specifically known, DHT is a suspect.

Time to call the doc? Not yet. It’s still just a statistical link, not a risk factor. More studies need to confirm the connection.

“We hope that upon such confirmation, we may be able to use early baldness as a clinical indicator of risk for prostate cancer,” says Zeigler-Johnson. If you’re worried, you may want to reinforce lifestyle changes that can lower your risk, such as eating a plant-based diet with no more than a pound of red meat a week (and little or no processed meats). “If you want to improve your prostate health, either for preventing cancer or BPH, follow the same guidelines for a healthy heart,” says Dr. McVary: “Exercise, eat a low animal-fat diet, and try to keep thin.”
Heart Disease

A recent Japanese meta-analysis of six studies, involving 40,000 men, showed a statistical link between MPB and heart disease. Men with severe baldness were about a third more likely to develop heart disease than men with a full head of hair. In this case, the link was to vertex baldness — the bald spot — not a receding hairline. “These studies found an association,” says cardiologist Nieca Golberg, M.D., a clinical associate professor at the NYU School of Medicine. “but it’s far from an established risk factor, such as high blood pressure or high cholesterol.”
If you’re concerned about possible increased cardiovascular disease risk, by all means take charge now. “There are important steps we can take to reduce risk,” says Dr. Goldberg. “Regular exercise, quitting smoking, getting cholesterol checked (and taking meds if you need them), lowering blood pressure—these all lower the risk of heart disease.”

What About Women?

While male pattern baldness is a guy thing, women after menopause often experience a related condition called “female pattern hair loss” (FPHL). It’s characterized not by receding hairline or a bald spot but by a gradual thinning over the crown of the head. It affects as many as 38 percent of women by age 70. Unlike the situation with men, FPHL isn’t tightly linked with excess androgens. Many women with the condition have no excess androgens, although it’s possible that their hair follicles may exhibit some hormonal imbalance. If your doctor does find high circulating androgen levels, though, he or she may want to check into other related conditions such as adult acne or obesity. Although not as well studied as in men, there are some associations between female pattern hair loss and heart disease, especially if it starts early, before age 55. If your hair is thinning, your doctor may want to check you for metabolic and cardiovascular risk. If you have thinning hair, it’s also important to check your iron status, since iron deficiency can cause hair loss. As with men, there are medications such as Minoxidil (Rogaine) that may help restore hair growth or reduce hair loss such as Minoxidil (Rogaine).

Other Kinds of Hair Loss

Male pattern, and female pattern, hair loss are the two most common causes of hair loss. But they are far from the only ones. Many factors—diseases such as diabetes, medications, chemotherapy, high fever, poor diet, hair dyes and more—can cause hair to thin or fall out. If you experience unusual hair changes, see your doc. As for treatment, there are a couple of medications approved by the FDA to treat male pattern baldness: Minoxidil (Rogaine), a solution you apply to your scalp, and finasteride (Propecia, Proscar), a pill that blocks certain androgens. Otherwise, the treatment for both men and women is hair transplantation.
