Yes, finasteride can stop hair loss for most people, but it’s not a permanent fix. It works by lowering DHT levels, the hormone responsible for shrinking hair follicles. This helps slow down hair loss and, in some cases, encourages regrowth.

That said, finasteride is more of a maintenance tool than a cure. If you stop taking it, hair loss will likely resume within months.

It works best for men with mild to moderate thinning, helping them keep the hair they have rather than bringing back what’s already gone.

Some people combine it with other treatments like minoxidil for better results.

What is finasteride and how does it work?

Finasteride is a prescription medication that helps slow hair loss by reducing DHT levels in the scalp. DHT (dihydrotestosterone) is a hormone that causes hair follicles to shrink over time, leading to thinning and baldness.

Finasteride blocks an enzyme called 5-alpha-reductase, which is responsible for converting testosterone into DHT.

By lowering DHT levels, finasteride helps protect hair follicles and extends their growth phase. This means existing hair stays in place longer, and some people may notice thicker, healthier strands over time.

Originally, finasteride was developed to treat an enlarged prostate (BPH), but researchers discovered its ability to slow hair loss. It was later approved for male pattern baldness in a lower 1mg dose. While it works well for many men, it’s not usually prescribed for women due to potential risks, especially during pregnancy.

Does finasteride actually work? What research says

Finasteride is one of the most effective hair loss treatments available, but it works best when started early. Studies show that most men experience a slowdown in hair loss and, in some cases, slight regrowth. Here’s what the numbers say:

After one year: Around 89% of men stop losing hair.
After two years: About 82% still maintain their hair.
After five years: Roughly 64% continue to see benefits.

While these results are promising, finasteride doesn’t work for everyone. Some men see little to no regrowth, but the key benefit is stopping further hair loss. It’s also worth noting that hair thinning is a progressive condition.

Over time, other factors like genetics, stress, or inflammation can still contribute to shedding, even while on the medication.

Can finasteride regrow lost hair?

Finasteride may help regrow hair in thinning areas, but it’s unlikely to bring back hair in completely bald spots. Its main job is to stop hair loss and preserve existing follicles.

Men with early-stage hair thinning may see some regrowth, especially on the crown. However, once a follicle has been inactive for too long, it’s much harder to revive.

If you're dealing with significant baldness, treatments like minoxidil, PRP therapy, or hair transplants might be needed for better results.

Think of finasteride as a way to freeze your hair loss where it is. The sooner you start, the better your chances of keeping what you have.

How long does it take to see results?

It usually takes 3 to 6 months to notice a difference, with full results taking up to a year. Hair growth is a slow process, and finasteride needs time to work.

At first, you might not see much change—or even experience a temporary shed. This is normal and means your follicles are shifting into a healthier growth phase.

Most people start seeing noticeable improvements around the 6-month mark, with peak results appearing after 12 months.

Patience is key. If you expect instant results, you’ll likely be disappointed.

But stick with it, and finasteride can be a game-changer for slowing hair loss and keeping your hair looking fuller for years to come.

Does finasteride work for women?

Finasteride is sometimes used for hair loss in women, but it’s not FDA-approved for this purpose. Some doctors prescribe it off-label for female pattern hair loss, but results are mixed, and it's generally not recommended for women who are pregnant or may become pregnant due to potential risks.

The reason finasteride is less commonly used for women is that female pattern hair loss isn’t always driven by DHT in the same way as male pattern baldness.

While some women see improvement, others may not respond as well. In many cases, doctors suggest alternatives like spironolactone, which also reduces androgen activity but is considered safer for women.

Why finasteride’s effectiveness declines over time

Finasteride helps slow hair loss, but it’s not a permanent fix. Many men notice it works well for the first few years, but after that, they may start seeing thinning again. This isn’t because the medication stops working—it’s because hair loss is a complex process influenced by more than just DHT.

Here’s why finasteride’s effects may fade over time:

Hair follicles weaken with age. Even with lower DHT levels, follicles naturally shrink as you get older.
Genetics play a role. Some people are more prone to hair loss, and finasteride can only do so much to counteract those genes.
Inflammation can contribute to thinning. Chronic inflammation in the scalp can weaken hair follicles, something finasteride doesn’t address.
Other hormones may be involved. While finasteride targets DHT, factors like cortisol (stress hormone) and poor circulation can also impact hair health.

If finasteride alone isn’t cutting it anymore, combining it with minoxidil, PRP therapy, or low-level laser therapy may help slow further loss.

How to use finasteride for best results

Finasteride works best when taken consistently. Skipping doses can reduce its effectiveness, so sticking to a daily routine is key.

For the best results:

Take 1mg once a day – It can be taken with or without food.
Be patient – Results take at least 3-6 months, with peak benefits seen after a year.
Don’t skip doses – Consistency is important for keeping DHT levels low.
Consider combining with other treatments – Minoxidil, PRP, and laser therapy can enhance results.
Monitor side effects – If you notice any unusual changes, consult your doctor.

Stopping finasteride will likely result in hair loss resuming within 3-6 months, so it’s a long-term commitment for those who want to maintain their hair.

Potential side effects of finasteride

Finasteride is well-tolerated by most people, but like any medication, it comes with possible side effects. Some are mild and temporary, while others are less common but more serious.

The most frequently reported side effects include:

Lowered libido or sexual function
Erectile dysfunction
Decreased semen volume
Breast tenderness or enlargement
Mood changes, such as anxiety or depression

For some men, these side effects go away after stopping the medication, but in rare cases, symptoms persist—a condition often referred to as post-finasteride syndrome (PFS).

Rare side effects can also occur, including:

Allergic reactions (rash, swelling, itching)
Testicular pain
Persistent fatigue or brain fog
Breast lumps or nipple discharge (requires medical attention)

If you experience any unusual or severe symptoms, it’s important to talk to your doctor.

Are there any better alternatives to finasteride?

If you're concerned about the side effects of finasteride or looking for a drug-free option, there are other treatments that can help slow hair loss and even promote regrowth. Some are backed by clinical studies, while others work best when combined with other therapies.

Here are some alternatives that might be worth considering:

Bio Pilixin Serum

Bio Pilixin Serum is a plant-based treatment designed to help reduce hair loss and support new growth. Unlike finasteride, it doesn’t alter hormone levels. Instead, it uses plant growth factors, stem cell technology, and active ingredients to strengthen hair follicles naturally.

Clinical studies on Bio Pilixin show promising results:

77% of users reported less hair shedding within 45 days.
93% saw a reduction in hair loss after 150 days.
73% experienced an increase in hair density after five months.

The formula contains key ingredients like Capilia Longa®, which has been shown to reduce hair loss by up to 89%, and niacinamide, which helps strengthen hair by increasing keratin production.

Users often notice less hair fall in the shower within a few weeks, making it a good option for those looking for a non-prescription treatment.

Minoxidil (Rogaine)

Minoxidil is one of the most well-known hair loss treatments and is FDA-approved for both men and women. It works by increasing blood flow to the scalp, which helps revitalize weak hair follicles and extend their growth phase.

Unlike finasteride, minoxidil is a topical solution or foam that needs to be applied directly to the scalp twice a day.

While it doesn’t block DHT, it encourages hair regrowth in thinning areas, making it a great option for those who want to regrow lost hair rather than just maintain what they have.

PRP (Platelet-Rich Plasma) therapy

PRP therapy involves drawing a small amount of your blood, separating the platelet-rich plasma, and injecting it into the scalp. These platelets contain growth factors that can help stimulate dormant hair follicles and encourage regrowth.

Many dermatologists recommend PRP therapy as a natural, drug-free alternative to finasteride, especially for people who are sensitive to medications.

Treatments are usually done once a month for three to four months, followed by maintenance sessions every few months.

Low-level laser therapy (LLLT)

LLLT is a non-invasive treatment that uses red light therapy to stimulate hair follicles, increase blood circulation, and improve hair thickness. It’s commonly used in laser caps, combs, or helmets, making it easy to use at home.

While results vary, studies suggest that consistent use for at least six months can lead to stronger, healthier hair. Many people combine LLLT with finasteride or minoxidil for better outcomes.

Hair transplants

For those dealing with advanced hair loss, a hair transplant is the only option that provides permanent results. The procedure involves moving healthy hair follicles from one part of the scalp to thinning or bald areas.

There are two main types:

FUE (Follicular Unit Extraction) – Individual hair follicles are transplanted for a more natural look.
FUT (Follicular Unit Transplantation) – A strip of scalp with hair follicles is transplanted, typically used for larger areas.

While hair transplants require a bigger upfront investment, they offer a permanent solution and don’t require ongoing medication.

Is finasteride right for you?

Finasteride is a good option for men who want to slow hair loss and maintain their existing hair, but it’s not for everyone. It works best for early to moderate hair thinning and requires long-term use to keep results.

If you’re experiencing significant shedding and want to take a preventative approach, finasteride could be a great fit.

However, if you’re worried about side effects or prefer natural alternatives, options like Bio Pilixin Serum, PRP therapy, or minoxidil might be worth exploring.

Always talk to a doctor to find the best treatment for your specific hair loss pattern and goals.

Conclusion

Finasteride remains one of the most effective medications for slowing hair loss, but it’s not a cure, and it doesn’t work for everyone. It helps maintain existing hair, but regrowth is usually limited to thinning areas, not completely bald spots.

For those looking for alternative options, treatments like Bio Pilixin Serum, minoxidil, PRP therapy, laser therapy, and hair transplants can also help. The best approach often involves combining multiple treatments for better, long-lasting results.

If you’re considering finasteride, think about your long-term commitment and whether the potential side effects are worth it for you.

No matter what route you take, early action is key—the sooner you address hair loss, the better your chances of keeping the hair you have.
