Why Do Men Bald More than Women? Is It Hormones? (2024)

Balding is a fact of life for many men—and the frustrating part is, women seem to get off easy. But why do men bald more than women?

Is it the genes? Hormones? Something in the water?

Not exactly.

The root of the problem lies in a combination of biological factors that men can’t exactly dodge. It’s all about androgens like dihydrotestosterone (DHT), which, for men, make hair follicles shrink over time, causing those once-thick locks to thin out and disappear.

While women aren’t immune to hair thinning, the reasons men go bald more often are written in their DNA and hormones. Men produce more testosterone, which gets converted to DHT—a hormone that is particularly unforgiving when it comes to keeping hair on your head. Women have lower levels of DHT, and their hair loss tends to be more subtle, resulting in thinning rather than the dramatic bald patches that men experience.

So, how exactly do androgens, genetics, and other factors come together to give men the short end of the hair stick?

Science of Hair Growth

Hair growth isn’t as simple as hair sprouting out of your head and just staying there. It’s actually a continuous cycle, and in both men and women, hair follicles go through three phases: anagen (growth), catagen (transition), and telogen (rest). The length of these phases, however, is where things get interesting—and where men tend to get the short end of the follicle stick.

Here’s the thing: men tend to have shorter anagen phases, meaning their hair spends less time growing and more time in the telogen phase, or “resting” (also known as "waiting-to-fall-out" mode). And thanks to our old friend testosterone (and its troublemaking byproduct DHT), the anagen phase can get even shorter as men age. This is the reason for testosterone and hair thinning in men and why androgenetic alopecia—aka male pattern baldness—is so common.

On the flip side, women tend to enjoy longer anagen phases, giving their hair more time to grow. Plus, they have lower levels of testosterone and DHT, which means their follicles don’t shrink as aggressively. So while women may experience hair thinning, it's usually not as rapid or as noticeable as the balding patterns seen in men.

Why is Hair Loss More Common in Men than Women?

Hair loss is an equal-opportunity problem—men and women both experience it. But let’s be honest: men bear the brunt of it, and often much earlier and more noticeably. In the United States, an estimated 85% of men experience significant hair thinning by the age of 50, while only about 40% of women face some degree of hair loss by that same age​. The reason is not just bad luck. There are clear, scientifically-backed factors that explain why men lose hair more than women.

Let’s break down the main reasons, from hormones to hair growth cycles.

1. Hormonal Differences: The Role of Androgens

When it comes to why men go bald faster, the most significant factor is hormones. Specifically, androgens—the male sex hormones—are responsible for many of the hair-related woes men face. And the biggest offender of all is dihydrotestosterone (DHT), often called the "hair assassin" for its relentless attack on hair follicles.

DHT is a byproduct of testosterone, and while it might sound harmless, it’s anything but for your hair follicles.

In men, higher levels of testosterone lead to higher levels of DHT. Once DHT binds to hair follicles, it begins to shrink them, weakening their ability to produce healthy, thick hair. Over time, those follicles shrink to the point of not being able to produce hair at all​. Women, on the other hand, have much lower levels of DHT, which protects their follicles from this kind of damage—most of the time. This is why androgenetic alopecia (male pattern baldness) affects men much more aggressively and earlier than it does women​.

2. Genetic Predisposition and Family History

You’ve probably heard it before: if your father, uncles, or grandfathers went bald, you might want to start stocking up on hats. But here’s the thing—male pattern baldness isn’t just passed down from your dad’s side. It’s a polygenic trait, meaning you can inherit it from both your mother’s and your father’s side of the family​.

For men, hair loss tends to follow a more defined pattern, starting with a receding hairline or thinning at the crown. Women, while they can also inherit genes for hair thinning, typically experience it in a more diffuse pattern across the scalp​. Thanks to these genetic factors, men are more prone to experiencing visible baldness, while women are more likely to experience subtle thinning.

3. Hair Growth Cycle Differences

Hair growth isn’t as straightforward as it might seem. Hair follicles go through three main phases: the anagen (growth), catagen (transition), and telogen (rest) phases. For men, these cycles tend to be shorter. That means hair spends less time in the growth phase and more time in the resting phase​.

Now, factor in DHT, which further shortens the growth phase (anagen) and you’ve got a recipe for rapid hair thinning. The hair doesn’t have time to grow long or thick before it falls out, making hair loss more noticeable in men. Women, on the other hand, have longer growth cycles, which means their hair stays in the anagen phase for longer periods, leading to less drastic hair loss​.

This helps explain why men seem to lose hair more quickly and visibly than women.

4. Lifestyle Factors and Stress

It’s no secret that lifestyle choices can impact your hairline, but men are often more affected by these factors than women. Stress, for example, can cause a type of temporary hair loss called telogen effluvium. This condition occurs when stress pushes more hair follicles into the resting phase prematurely, causing a noticeable increase in hair shedding​.

While both men and women can experience stress-induced hair loss, men’s susceptibility to androgenetic alopecia means that stress can compound existing genetic and hormonal factors, speeding up hair loss​. Smoking, poor diet, and lack of exercise—common lifestyle factors that increase the risk of heart disease—also worsen hair loss, particularly in men​. Women, by comparison, may have different coping mechanisms, such as more consistent hair care routines, which can help mitigate the visible effects of stress on hair.

5. Aging and Hair Loss Patterns

Finally, there’s the unavoidable factor of aging. As both men and women age, their hair growth cycles slow down, but men tend to lose hair in a more defined pattern. Men typically experience a receding hairline or crown balding, while women tend to experience overall thinning across the entire scalp​.

The male and female hairline are totally different from each other. The difference is that women tend to retain their hairline and often experience less dramatic thinning. That’s why you’ll see more men with distinct bald patches or full baldness, while women rarely go completely bald. The combination of genetics, hormones, and aging simply accelerates the process in men​. The combination of genetics, hormones, and aging simply accelerates the process in men. And as you age, medical issues often increase, which can impact hair health as well. Side effects from medications, autoimmune conditions, and other age-related health issues can exacerbate hair loss, making it even more challenging to maintain hair density over time.

Treatment Options for Male and Female Hair Loss

While hair loss might not always have a “miracle cure,” there are several science-backed ways to slow it down or manage it effectively. Both men and women facing androgenetic alopecia have access to a range of treatments that target the underlying causes, whether it’s hormonal imbalances, follicular sensitivity to DHT, or aging. Here’s a breakdown of the most effective options.

1. Medications for Men (Finasteride and Minoxidil)

When it comes to hair loss treatments for men, the two go-to options are finasteride and minoxidil—both FDA-approved and widely researched. Finasteride works by blocking the enzyme that converts testosterone into dihydrotestosterone (DHT), the hormone most responsible for shrinking hair follicles and triggering male pattern baldness​.

By reducing DHT levels, finasteride helps prevent further hair loss. However, be prepared for a long-term commitment; stop taking it, and hair loss can resume faster than you can say “receding hairline.” Important note: Finasteride is generally not recommended for women, as it has been shown to cause birth defects if taken during pregnancy. For women, it’s essential to consult a healthcare provider for safer alternatives.

Minoxidil, on the other hand, doesn't mess with your hormones. Instead, it boosts blood flow to the scalp and revitalizes dormant hair follicles, promoting regrowth in thinning areas​. It’s available as a topical treatment (hello, easy application), and while it might not stop hair loss entirely, it can help add density to what’s left. One thing to keep in mind: you’ll need to use it consistently to see results, and like finasteride, stopping the treatment might cause your gains to vanish.

The catch with these treatments? Results vary, both require a long-term commitment, and they come with a recurring cost—think monthly expenses for the long haul. No “once and done” solutions here, folks.

2. Hormonal Treatments for Women

For women, hair loss often takes a different approach, especially when related to menopause and hormonal changes. Enter hormone replacement therapy (HRT) and oral contraceptives, both of which help to rebalance the hormonal shifts that contribute to hair thinning​. These treatments work by either supplementing estrogen levels or regulating the hormonal fluctuations that typically happen post-menopause.

Minoxidil is another effective treatment option for women, similar to men, though women tend to use a lower concentration. While most women won’t need finasteride (since they have lower DHT levels to begin with), hormonal treatments are a common route to preserving hair post-menopause​.

One note: hormonal treatments are best used under a doctor’s guidance, as they come with their own set of potential side effects and aren’t a “one-size-fits-all” solution.

3. Low-Level Laser Therapy (LLLT)

Here’s one treatment both men and women can agree on: low-level laser therapy (LLLT). This non-invasive treatment has gained popularity because of its ability to increase blood flow to the scalp, stimulate hair follicles, and promote regrowth​.
LLLT uses low-level lasers to encourage hair follicles to exit the resting phase and enter the active growth phase, which can help slow down thinning and even reverse some hair loss.

The beauty of LLLT? It’s relatively easy to use—think of it like shining light therapy directly on your scalp. Several at-home devices (like wearable caps) are available, allowing for treatment without needing to visit a clinic. Studies have shown that LLLT can be effective in both men and women, making it one of the few treatments that doesn’t discriminate based on gender​.

While it won’t necessarily bring back a full mane overnight, laser therapy has shown promising results when combined with other treatments, like minoxidil or hormonal therapy. So, if you’re looking to preserve those follicles for a little longer, this might be an option worth exploring.

When choosing the right laser hair growth device, Theradome stands out as the leading choice for both men and women seeking effective hair restoration.

Conclusion

So, why do men bald more than women?

It boils down to a combination of genetics, hormones (thanks, DHT), and differences in hair growth cycles. While hair loss might be inevitable for many men, there’s no shortage of ways to tackle it—from medications to laser therapy. And while women don’t go fully bald as often, they’re not completely off the hook either. In the end, understanding the science behind hair loss helps men and women make informed choices to keep their hair for as long as possible.
