Hair loss is a common struggle that can take a toll on confidence. By middle age, a majority of men will experience some degree of balding – in fact, male pattern baldness affects up to 85% of men by age 50. Unfortunately, a lot of misinformation floats around about hair loss treatments, which can scare people away from effective solutions. If you've been sifting through online forums or chatting with mates at the pub, you've probably heard a few myths about what works and what doesn't.
One treatment often surrounded by rumors is finasteride. Finasteride (brand name Propecia® for hair loss) is a widely used, Therapeutic Goods Administration (TGA)-approved prescription medication for male pattern hair loss in Australia. It's helped countless men slow down their receding hairlines and regrow hair. Yet, despite being around for decades, finasteride is subject to many misconceptions that might make some men hesitant to try it.
In this article, we'll take a conversational deep dive into five common myths about finasteride and hair loss – and bust them with factual, science-backed information. No jargon overload here, just an honest look at the claims you've heard versus what's actually true. By clearing up these myths, we hope to help Aussie blokes (and anyone else curious) make informed decisions about treating hair loss. Let's separate fact from fiction!
"Finasteride doesn’t work for hair loss – it’s all hype." If you've heard this, rest assured it's a myth. The reality is that finasteride is one of the most effective treatments available for male pattern baldness. It wouldn't be TGA-approved and doctor-recommended if it didn't consistently deliver results.
How Finasteride Works: Finasteride targets the hormonal cause of male pattern hair loss. In genetically predisposed men, a hormone called dihydrotestosterone (DHT) binds to hair follicles and gradually shrinks them, causing hairs to grow back thinner and shorter each cycle. Over time, DHT can make follicles so small that they stop producing visible hair – hello, bald spot. Finasteride comes to the rescue by blocking 5-alpha-reductase, the enzyme that converts testosterone into DHT. By cutting DHT levels, finasteride protects your hair follicles from that hormone’s withering effect, allowing them to keep producing healthy hairs. In simple terms, finasteride takes the foot off the brake pedal (DHT) that's slowing your hair growth.
What does this mean for results you can see? Primarily, finasteride slows or stops further hair loss, and in many cases, it also stimulates regrowth of hair that's started to thin. It's not an overnight miracle – you have to stick with it for several months to a year to gauge its effect – but numerous studies and real-world use have shown it works for the vast majority of men.
Clinical Evidence: Don’t just take our word for it. Clinical studies have demonstrated impressive effectiveness for finasteride:
Those numbers are pretty convincing. When used as directed (1 mg daily for hair loss), finasteride has a success rate around 80–90% or higher in preventing hair loss progression. Many men even see improvement – thicker, fuller hair – especially in areas like the crown of the head. It tends to work best on slowing hair loss at the crown and mid-scalp, though some men notice improvements at the hairline as well.
It's worth noting that finasteride works gradually. You might not notice much change in the first 3–6 months. This can lead skeptics to prematurely say "See, it's not doing anything!" But by 6 to 12 months, you should see that your hair loss has stopped getting worse, and you may start spotting new growth or thickening in thinning areas. Patience is key – hair cycles take time to show results. Most studies assess results at the 1-year mark and beyond.
Also, finasteride’s benefits will continue as long as you keep taking it. So if you're looking at photos of men after 5 years on finasteride, you'll often see they have maintained significantly more hair than they would have without treatment. In summary, finasteride absolutely is effective for the majority of men dealing with androgenetic alopecia (male pattern baldness). It addresses the root cause (DHT) and has the data to prove its worth.
So, if you've been avoiding finasteride because someone told you "it doesn't work," you can confidently put that myth to rest. The science says otherwise. Finasteride won’t regrow a full head of hair overnight – no treatment can do that – but it can help you hang on to the hair you've got and even regain some that you've lost, giving you a better chance at a fuller head of hair over time.
"Finasteride will make you impotent forever." This alarming myth has been making the rounds on internet forums and scaring off many men from even considering the medication. It's easy to see why this one gets so much attention – sexual health is a big deal! However, the idea that finasteride commonly causes severe or permanent impotence (erectile dysfunction) is not supported by scientific evidence. Let's unpack the facts in a down-to-earth way.
First off, it’s true that finasteride – like any medication – can have side effects. Because finasteride works by altering hormones (lowering DHT, which is a derivative of testosterone), some users worry it will affect sexual function. The known potential side effects related to sexual health include things like a weaker libido (sex drive), difficulty getting or maintaining an erection, or decreased semen volume. These side effects have been reported, but here’s the important part: they occur in a small percentage of men, and they are usually temporary.
Let's look at what the research actually shows about finasteride and sexual side effects. In clinical trials of the 1 mg dose for hair loss (Propecia):
These numbers show that only a small minority of men get these side effects, and the rates aren’t that far off from men who weren’t even taking the drug (placebo). For context, sometimes just the anxiety about potential side effects – known as the nocebo effect – can cause men to experience issues that have no physiological cause. So it’s possible some of those placebo guys had issues just thinking something might happen.
Crucially, the side effects were usually reversible. Clinical studies found that any sexual side effects went away after men stopped taking finasteride, and even in many men who stayed on the medication, the side effects disappeared with continued use. The body can adjust over time. According to Harvard Medical School experts, the side effects of a medication usually go away when you stop taking it. Finasteride is no exception: if a man does experience something like ED or low libido on finasteride and it's bothersome, discontinuing the drug typically resolves the issue. It’s not a permanent change to your body.
"Important: The myth of "permanent impotence" largely stems from reports of a condition you might see online called "Post-Finasteride Syndrome" (PFS). A very small number of men have claimed long-lasting sexual dysfunction even after stopping finasteride. The existence and cause of PFS are controversial and still being studied. To date, there's no conclusive proof that finasteride causes persistent problems in otherwise healthy men. Other health factors could be at play in those cases, and they represent a tiny fraction of users. The vast majority of men do not experience persistent side effects."
So, what’s the bottom line? Finasteride is generally very well tolerated. Millions of men have used it without sexual side effects at all, or with very mild ones that often go away. If side effects do occur, they are usually mild and temporary. For example, a slight dip in libido might improve after a few weeks as your body adapts, or it will return to normal after stopping the medication. Permanent impotence is not a typical outcome – it's more of an internet scare story than a reality for the average user.
That said, every individual is different. If you have pre-existing erectile dysfunction or other health issues, discuss with your doctor whether finasteride is appropriate. But if you're a generally healthy guy, the risk of long-term sexual side effects from finasteride is extremely low. Studies estimate only about 2% (or less) of users have any sexual side effects, and those are usually reversible. Compare that to the benefit of keeping your hair – for many men, the trade-off is well worth it.
To put it in perspective: You're far more likely to keep your hair on finasteride than you are to lose your bedroom performance. The myth of finasteride causing widespread permanent impotence is busted. It’s mostly based on fear and a few anecdotal reports, not the actual statistical reality. If you’re worried, talk it over with a healthcare professional, but don’t let exaggerated claims stop you from considering a treatment that could genuinely help your hair.
"Finasteride is something only older men use. I'm too young for it." This myth likely comes from a couple of misconceptions. Some people think hair loss treatments are like a last resort for men in their 40s, 50s, or beyond. Others might associate finasteride with its original use for enlarged prostates (a condition typically affecting older men) and assume a young guy shouldn't be touching the stuff. Let's clear this up: finasteride is NOT just for older men. In fact, if you're a younger man experiencing hair loss, you might be the ideal candidate for finasteride.
Hair loss can start early: Male pattern baldness often begins in a man's 20s or 30s – sometimes even late teens. By the time many men are in their mid-20s, they may notice a receding hairline or thinning at the crown. It’s a myth that hair loss only hits when you’re older; it’s largely genetic and hormonal, and can kick in at a young age. The earlier it starts, the more hair you stand to lose over a lifetime if you don't intervene.
Why earlier treatment is better: Finasteride works by preserving the hair you currently have and preventing miniaturization of follicles. If you start treatment earlier in the hair loss process, there are more healthy hair follicles left to save from DHT damage. Think of it like protecting a fleet of ships before half of them sink – your chances of keeping a full fleet (full head of hair) are higher if you act early. Medical experts note that the greatest benefit of finasteride is in men in the early stages of hair loss. For example, in one 2-year study, only 17% of men with early male pattern baldness who took finasteride kept losing hair, versus 72% of similar men on placebo who continued to go bald. That’s a huge difference, underscoring that starting treatment before hair loss becomes severe can yield the best results.
Clinical trials in younger men: Finasteride’s approval for hair loss was actually based on trials in men aged 18 to 41. That was the target demographic in testing because those are the ages when male pattern baldness typically first becomes noticeable and treatment can be most effective. So the idea that it's only meant for "old guys" is incorrect – it was literally designed and studied for younger adult men. (The reason efficacy "has not been demonstrated in men over 41" in the official info is simply because the original studies didn't include older men, not because it suddenly stops working at 42. Many doctors do prescribe it to older men too, often with success, but younger men shouldn't hesitate to use it if needed.)
Preventive vs reactive approach: Some younger men think they should wait until they're older or "truly bald" before using something like finasteride. In reality, waiting is not a good strategy if your goal is to keep your hair. Finasteride is best used as a preventive measure – it keeps you from losing more hair rather than regrowing a totally bald scalp. If you wait until hair loss is advanced (say, you have large bald patches), finasteride may still help slow further loss, but it won't miraculously sprout hair on a completely shiny scalp. There need to be functional follicles to nourish. That's why dermatologists often recommend that men start finasteride as soon as hair loss becomes bothersome and noticeable, rather than delaying. Starting in your 20s or 30s when hair loss first appears can lock in more of your hair for the long haul.
To be clear, finasteride is approved for adult men of all ages (18 and up). There's nothing inherently "wrong" with a 25-year-old or 30-year-old taking finasteride – on the contrary, that might be an ideal time to use it. The myth that it's only for older men likely persists because:
So, if you're a younger guy noticing thinning hair and you're hesitating to seek treatment because you think finasteride is only for your dad or your grandad – think again. Tackling hair loss early with finasteride can actually yield better results than starting late. Many men in their 20s and 30s in Australia are using finasteride to great effect. It's all about keeping the hair you have and staying ahead of the game.
In summary, finasteride is for any adult man dealing with male pattern hair loss, not just seniors. Balding is a progressive condition that doesn't care about your age, and neither does finasteride – it can help halt that progression whenever it starts. The sooner you separate this myth from fact, the sooner you can make a proactive decision about your hair.
"If you ever stop taking finasteride, all the hair you gained will fall out instantly!" This myth can make finasteride sound like a scary lifelong trap – as if the day you forget a pill, your hair will suddenly jump ship. Let's soothe those fears. While it’s true that finasteride’s benefits are not permanent once you discontinue the drug, stopping finasteride does not cause an immediate, dramatic shed in a matter of days. You won't wake up the morning after your last pill to find your pillow covered in all your hair. The process is more gradual and simply reverts to your natural hair loss progression.
Here's what really happens if you stop finasteride: Because finasteride was suppressing your DHT levels, once it's out of your system, DHT will slowly rise back to its original levels and resume affecting your hair follicles. In the absence of the drug, your hair will progressively return to its pre-treatment state over time. Essentially, you'll start losing hair again at the rate you were before you started finasteride. Any extra hair that finasteride helped you keep or regrow isn't "immune" to DHT without the medication's protection.
Studies and clinical experience have shown that when men stop finasteride, they tend to lose the hair they've gained or maintained within about 6 to 12 months after discontinuation. For example, one health resource notes that if you stop taking it, you'll probably lose any hair that grew from the treatment over the next year. Hair count typically declines back to the level it would have been if you had never taken the medication at all. But this happens gradually, not overnight.
Let's break down the timeline:
The key point is that hair loss resumes its normal course. Finasteride doesn't make hair loss worse than it would have been; it just pauses it while you're on it. When you stop, you "un-pause," and hair loss continues from there. It's a myth that stopping finasteride creates some special rapid fallout. What people sometimes misinterpret as a sudden loss is just the natural progression catching up, especially if they stop after being on it for years. If you maintained much more hair thanks to finasteride, then stopping it might eventually reveal how much hair you would have lost in those years – which can seem like a lot, but remember, without finasteride you would have been losing it gradually anyway.
Another way to think of it: Finasteride is like paying rent to keep your hair. If you stop paying rent (stop the medication), you don't get to keep living there (the new hair or maintained hair). But the landlord isn't going to kick you out in a single day; you'll have a grace period (months) before you lose your "lease" on those hairs.
So, does finasteride require a long-term commitment? Yes, ideally it’s a long-term treatment if you want to continue preserving your hair. Many men stay on it for years, even decades, to maintain their results. If you stop, you should fully expect that over time your hair loss will continue from where it left off. However, don't let the fear of a catastrophic immediate shed keep you from using it. The process is reversible (start again and you can halt the loss again) and gradual.
Long-term management: Think of treating male pattern hair loss like managing a chronic condition – similar to taking blood pressure medication. If you stop treating high blood pressure, your blood pressure will go back up; if you stop treating hair loss, your hair loss will come back. It’s as simple as that. There’s no cure that permanently fixes hair loss (at least not yet), so continuous treatment is the strategy that works. Finasteride is a cornerstone of that strategy.
In conclusion, stopping finasteride will eventually lead to loss of the hair it was preserving, but not in an immediate, single swoop. The hair will be lost gradually over several months as your follicles once again feel the effects of DHT. This myth is busted in the sense that the "immediate" part is wrong. Of course, it's wise to only start finasteride if you're prepared for the idea that you should keep taking it to maintain the results. If you do stop for some reason, know that you have a bit of time and things won't free-fall in one day. And if you restart it soon enough, you might regain what was lost in the interim.
"I can just use natural remedies or supplements – they work just as well as finasteride for hair loss." In the quest to avoid medications, many people turn to so-called "natural" hair loss solutions – from herbal pills to special shampoos, scalp massages, vitamins, and more. There's an entire industry of products claiming to be natural hair loss cures. While some of these remedies are harmless and a few might have some benefits, none have shown anywhere near the effectiveness of finasteride (or other proven treatments) in rigorous scientific studies. The idea that they work just as well is, unfortunately, a myth.
Let's discuss a few common natural or alternative approaches and what we know about them:
The Australian Better Health Channel sums it up well: a number of other treatments (massage, supplements, herbs like saw palmetto, zinc, amino acids, lotions, tonics) have been suggested for hair loss, but none of these have been shown to promote hair growth or prevent hair loss. That’s a clear statement based on available evidence. Essentially, aside from proven medical treatments, most alternative remedies don’t pass the scientific test. They might be circulating due to anecdotal success stories or clever marketing, but when put under the microscope of clinical research, they haven't delivered convincing results.
On the other hand, finasteride's results are backed by robust clinical trials and decades of use. Regulatory agencies like the TGA approved finasteride for hair loss because the data showed it works and is safe for most users. No "natural" remedy has earned such approval for androgenetic alopecia, because none have demonstrated a comparable level of efficacy. If one did, it wouldn't be considered an alternative treatment for long – it would become a mainstream treatment!
That’s not to say you can't explore natural options if you're curious. Just do so with realistic expectations. Some men use things like saw palmetto or pumpkin seed oil if they absolutely cannot take finasteride (due to side effects, etc.), but they generally understand that the odds of significant improvement are much lower. Natural remedies might have a placebo benefit or make you feel proactive, and a few might slightly help hair health, but none can match finasteride in actively combatting the hormonal cause of male pattern baldness.
If you're serious about treating hair loss, evidence-based treatments are your best bet. These include:
Natural or OTC supplements are, at best, complementary. You might take some general hair wellness supplements for peace of mind, but don't expect them to stop genetic hair loss. It’s always wise to discuss with a healthcare provider before starting any treatment, natural or otherwise. They can help you sort myth from fact. And if a certain natural remedy truly had the same effect as finasteride, you can bet it would be front-page news in the dermatology world and every hair specialist would be using it. The fact that finasteride and minoxidil still reign supreme is telling.
Myth busted: When it comes to measurable results in hair count and preservation, natural remedies just don’t stack up to finasteride. By all means, live a healthy lifestyle and use gentle hair care products – those will support the overall condition of your hair. But if someone claims a natural potion or pill works "just as well" as finasteride, be skeptical and look for the evidence. Chances are, it's marketing or hearsay rather than science. Stick with what’s proven if you want the best shot at keeping your hair.
When it comes to treating hair loss, knowledge is power. By debunking these common myths about finasteride, we see a clearer picture: Finasteride is a clinically proven, effective treatment for male pattern baldness, not some scam. It works for most men, especially when started early, and can make a real difference in slowing or even reversing hair loss. The scare stories about side effects are largely exaggerated – serious adverse effects are rare, and the medication is considered safe for long-term use by medical authorities. Likewise, waiting until you're older or hoping that vitamins and herbs will rescue your hair are strategies that usually end in disappointment. Separating myth from fact means you can approach hair loss with a level head and realistic options.
For Australian men dealing with hair loss, the good news is that getting help is easier and more discreet than ever. Finasteride is a prescription medication, but you don’t necessarily need to visit a clinic in person to get it. Services like NextClinic allow you to consult with a doctor online and get a finasteride prescription from the comfort of home – no awkward pharmacy trips or long GP wait times. Essentially, if you decide that finasteride is right for you, you can have it delivered to your door in a discreet package. This convenience has removed a lot of barriers for men who might have been too embarrassed or busy to seek treatment before.
In summary, don't let misinformation stop you from addressing hair loss. If your hair is important to you, evidence-based treatments like finasteride (and often used alongside minoxidil) are worth considering. Talk to a healthcare professional about your options – armed with facts, not myths. Hair loss can feel like an uphill battle, but with the right knowledge and tools, you have a fighting chance to keep your locks for longer. Remember, you're not alone, and treatments do exist that can genuinely help. Here’s to cutting through the noise and making confident choices about your hair!
Q: Is Finasteride really effective for hair loss?
Yes – Finasteride has been proven to be effective for male pattern hair loss in the majority of men. Studies show it can stop hair loss in over 90% of users, with a significant number also seeing hair regrowth. It works by blocking DHT, the hormone that causes follicle shrinkage, thereby preserving existing hair and often making thinning areas thicker over time.
Q: Will Finasteride cause permanent sexual side effects?
For most men, no. Sexual side effects (like lower libido or erectile dysfunction) are uncommon – around 1-2% of users – and importantly, they are typically reversible. If a side effect occurs, it usually goes away after discontinuing the medication (and sometimes even with continued use as the body adjusts). Permanent issues are extraordinarily rare, and no conclusive evidence links finasteride to long-term impotence in the general population.
Q: What happens if I stop taking Finasteride?
If you stop finasteride, you will likely gradually lose the benefit it was providing. Over several months, your DHT levels will return to normal and your hair loss will resume its natural progression. Any hair that was maintained or regrown thanks to finasteride may be lost over the next 6–12 months after stopping. However, stopping does not cause an immediate massive shed – it’s a gradual reversal to your baseline state. Consistent long-term use is key for sustained results.
Q: How can I get Finasteride online in Australia?
In Australia, finasteride is a prescription medication, but you can obtain it through our online prescription service. NextClinic allows Australian men to have an online consultation with a licensed doctor. If deemed appropriate, the doctor can write a prescription and you can dispense Finasteride at any pharmacy with an e-script token. This process is legal, safe, and TGA-regulated – essentially an easier, more discreet way to get finasteride without needing a face-to-face doctor's appointment.
