When considering finasteride, it’s important to understand both the benefits and risks. Many men experience slowed hair loss and, with consistent use, may see thicker hair and even some regrowth. Achieving visible improvement takes time and daily treatment.

Always consult a licensed clinician before starting finasteride to ensure it’s safe and appropriate for you.

What Is Finasteride?

Finasteride is a prescription medication that belongs to a class of drugs called 5-alpha reductase inhibitors. It is FDA-approved to treat two conditions in men: benign prostatic hyperplasia (BPH), which is an enlarged prostate, and androgenic alopecia, more commonly known as male pattern hair loss.

By inhibiting a specific enzyme, finasteride reduces levels of a hormone that causes hair follicles to shrink. This helps slow hair loss and, in some cases, promote regrowth.

History and FDA Approval for Hair Loss

The development of finasteride for hair loss began with research linking male hormones to baldness. In 1992, finasteride received FDA approval under the brand name Proscar (5 mg) for treating benign prostatic hyperplasia. Five years later, the 1 mg dose was approved as Propecia for male pattern hair loss, establishing it as a targeted medical treatment for androgenetic alopecia.

How Finasteride Works in the Body

Finasteride works by blocking the enzyme 5-alpha reductase, which converts testosterone into dihydrotestosterone (DHT). This reduction is about 70% in the bloodstream and up to 90% in the prostate and it helps prevent DHT from shrinking hair follicles. As a result, hair loss slows, and many men experience thicker, healthier hair.

Finasteride doesn’t completely eliminate DHT, so its primary effect is to slow hair loss rather than stop it entirely. If the medication is discontinued, DHT levels typically return to normal within about two weeks.

Finasteride: What to Expect (& What to Watch)

Finasteride is an important treatment for male pattern hair loss because it directly targets the hormonal cause. It slows follicle shrinkage, preserves existing hair, and can improve density over time. Understanding what to expect helps you set realistic goals and monitor progress effectively.

Knowing how finasteride differs from other treatments, such as minoxidil, is also important. The next sections explain why finasteride works so well, outline the typical hair growth timeline, and highlight what to monitor for safe, effective results.

Why finasteride is a cornerstone for male hair loss

Finasteride is considered a primary treatment for male pattern baldness because it directly targets the underlying hormonal cause of the condition. Androgenic alopecia is driven by the hormone dihydrotestosterone (DHT), which binds to receptors in scalp hair follicles, causing them to shrink over time. This process, known as miniaturization, results in shorter, finer hairs until growth eventually stops.

Unlike many other treatments that work by stimulating hair growth without addressing the cause, finasteride intervenes at the source. By reducing the body's production of DHT, it helps protect hair follicles from miniaturization.

This mechanism makes it a powerful tool for preserving existing hair, slowing the progression of hair loss, and, for many men, improving hair density and thickness. Its proven ability to address the root of the problem is why so many healthcare providers recommend it as a first-line therapy for androgenic alopecia.

Key differences from other hair loss treatments

When considering hair loss treatments, it’s helpful to understand how finasteride differs from other popular options, most notably minoxidil. Their mechanisms of action are fundamentally different, which is why they are sometimes used together. Thinking about these differences can help you and your doctor decide on the best approach for you.

Finasteride is a systemic treatment that works from the inside out. It addresses the hormonal aspect of hair loss directly. In contrast, minoxidil is a topical solution that works as a growth stimulant on the scalp.

Here are the key differences:

Mechanism: Finasteride is a DHT blocker, tackling the hormonal cause of hair loss. Minoxidil is a vasodilator that is believed to increase blood flow and prolong the growth phase of hair follicles.
Administration: Oral finasteride is taken as a daily pill. Minoxidil is applied directly to the scalp as a liquid or foam, typically twice a day.
Primary Goal: Finasteride is primarily aimed at stopping the progression of hair loss and preserving hair. Minoxidil is focused on stimulating new growth.

What results most men can realistically expect

Setting realistic expectations is crucial when starting finasteride. The results are not immediate and require patience and consistent daily use. For most men, the primary benefit is the stabilization of hair loss, meaning you stop losing more ground. This alone is a significant victory in managing pattern hair loss.

Beyond stabilization, many users see visible improvements in hair growth and hair count. Clinical studies show that a reversal of hair loss, seen as an increase in hair count, can begin to appear within the first 12 months of treatment. This often translates to hair that appears thicker and fuller.

However, results vary from person to person. Finasteride is most effective at preventing further loss and reviving miniaturized but still-active follicles. It is less likely to regrow hair in areas that have been completely bald for many years. Consistent use is key, as stopping the medication will lead to a reversal of its benefits.

How it works in male AGA

For men experiencing androgenetic alopecia (AGA), or male pattern hair loss, the process can be frustrating. The good news is that finasteride offers a scientifically proven way to fight back. It works by directly targeting the hormonal mechanism that drives this specific type of hair loss.

The key to its success lies in its ability to reduce levels of dihydrotestosterone (DHT) at the scalp level. By doing so, it helps to break the cycle of hair follicle miniaturization that defines male pattern hair loss. Let's look closer at this mechanism and why DHT is so important in this process.

Mechanism: blocking DHT at the follicle level

Finasteride’s effectiveness comes from its precise action within your body. It is classified as a 5-alpha reductase inhibitor, and this enzyme is responsible for converting testosterone into the more potent androgen, dihydrotestosterone (DHT). Specifically, the type II isomer of 5-alpha reductase is highly concentrated in the outer root sheaths of hair follicles.

By acting as a competitive inhibitor, finasteride blocks this enzyme, significantly reducing the amount of testosterone that gets converted to DHT directly in the scalp. This local reduction of DHT is crucial.

Lowering DHT levels at the follicle helps to shield it from the hormone's damaging effects. This allows the hair growth cycle to normalize, preventing further miniaturization and creating a better environment for healthier, stronger hair to grow. The drug's targeted action is what makes it a powerful tool against androgenetic alopecia.

Why DHT matters in androgenetic alopecia

To understand why finasteride works, you need to understand the role of dihydrotestosterone (DHT) in androgenetic alopecia. In men who are genetically predisposed to pattern hair loss, hair follicles on the scalp become sensitive to DHT. This sensitivity is the root cause of the condition.

When DHT binds to androgen receptors in these sensitive follicles, it triggers a process called miniaturization. This causes the anagen (growth) phase of the hair cycle to become progressively shorter and the telogen (resting) phase to become longer.

Over time, the affected follicles shrink and produce hairs that are shorter, finer, and less pigmented. Eventually, the follicles may become so small that they stop producing visible hair altogether, leading to the classic patterns of male baldness. By reducing DHT, you interrupt this destructive cycle.

How finasteride preserves and thickens hair

By significantly lowering DHT levels, finasteride provides a lifeline to struggling hair follicles. With less DHT present to cause miniaturization, follicles that were shrinking can begin to recover. This intervention has two main effects: preservation and thickening. First, it acts as a defensive measure, preserving the hair you still have by halting the progression of hair loss.

For many men, this is the most important benefit, as it stops the thinning from getting worse. Second, by relieving the hormonal pressure on the follicles, finasteride can reverse some of the miniaturization process.

This allows the hair growth cycle to lengthen, giving follicles the chance to produce thicker, healthier, and more pigmented hairs. Over time, this improvement in hair quality contributes to an increased overall hair count and density, making your hair appear fuller and more robust.

Oral finasteride: efficacy & timelines

When taking oral finasteride for hair loss, the standard treatment involves a 1 mg dose taken once daily. Understanding the timeline for results is key to staying motivated, as improvements are gradual and require consistent finasteride therapy. You won't see changes overnight.

It typically takes several months of continuous use to assess the full effect of the treatment. In the following sections, we’ll break down what you can expect at the 3, 6, and 12-month marks, review the findings from long-term studies, and identify who tends to respond best to the medication.

When to expect visible results (3, 6, 12 months)

Patience is essential when starting oral finasteride. The medication works on the hair growth cycle, which is a slow process. Visible results unfold over several months, and it's important to stick with the daily 1 mg dose to see the benefits. Your progress can generally be tracked along the following timeline.

Here’s a breakdown of what you might expect:

3–6 Months: Hair shedding slows; early stabilization.
6–12 Months: Noticeable thickening and new growth.
12+ Months: Peak results; consistent use required for maintenance.

Long-term studies on efficacy and durability

The effectiveness of finasteride isn't just a short-term fix; it has been proven durable in long-term clinical studies. One of the most cited is a 5-year multinational study on the use of finasteride 1 mg for androgenetic alopecia. This study demonstrated that the positive effect of finasteride on hair growth was sustained over the entire period.

The study showed that men continuing the finasteride use not only maintained their hair count but also experienced continued improvement for up to two years, with results stabilizing thereafter. In contrast, the placebo group continued to lose hair steadily over the 5 years.

Furthermore, this long-term data provided valuable insights into the safety of finasteride use. It found that the incidence of drug-related sexual side effects was low and actually decreased over time, dropping to 0.3% or less by the fifth year of treatment. This suggests that for many men, the treatment is both effective and well-tolerated long-term.

Best responders: earlier vs advanced hair loss

While finasteride can be effective for many men, its results often depend on the stage of hair loss at which treatment begins. Generally, men in the earlier stages of male pattern baldness are considered the best responders. This is because the medication works by protecting and reviving hair follicles that are miniaturizing but still functional.

If you start treatment when you first notice thinning or a receding hairline, you have more viable follicles for finasteride to save. The drug is highly effective at halting the progression of pattern hair loss and can thicken existing thinning hairs, leading to a visible increase in density.

In cases of advanced hair loss, where large areas of the scalp have been smooth and bald for many years, the follicles may have become dormant or scarred. In these situations, finasteride can still help preserve the remaining hair but is less likely to regrow hair in completely bald spots. Starting early gives you the best chance for optimal results.

Safety profile & side effects (what studies show)

A crucial part of any treatment discussion is understanding the safety of finasteride. While it is an effective medication, it does come with a risk of potential side effects. Clinical trials and post-marketing surveillance have provided a clear picture of the possible adverse events, allowing for an informed conversation between you and your doctor.

The majority of side effects are related to sexual function and mood, though most men do not experience them. Let’s examine the common side effects, their reported incidence rates, and address the concerns surrounding "post-finasteride syndrome."

Common side effects (sexual function, mood changes)

The most widely discussed side effects of finasteride involve sexual function. Because the drug works by altering androgen levels, it can, in a small subset of men, lead to adverse effects in this area. It's important to be aware of these potential changes when considering treatment.

Additionally, some reports and post-marketing data have linked finasteride to mood changes and psychological side effects. While less common than sexual side effects, these should also be part of your discussion with a healthcare provider.

The most frequently reported adverse effects include:

Sexual Dysfunction: This can manifest as erectile dysfunction (ED), a decrease in libido (sex drive), and a reduction in ejaculatory volume.
Gynecomastia: Some men may experience tenderness or enlargement of breast tissue.
Mood Changes: Reports include depression, anxiety, and, in rare cases, suicidal ideation.
Other Effects: Dizziness and weakness have also been reported.

Incidence rates in clinical trials

To understand the real-world risk, it’s helpful to look at the incidence rates reported in large-scale clinical trials. These studies provide data on how frequently side effects occurred in men taking finasteride compared to those taking a placebo. This context is important for making an informed decision about the treatment.

In major studies for male pattern hair loss, the rate of sexual adverse events was low. For example, some reviews of clinical trials show that issues like erectile dysfunction, decreased libido, and ejaculatory disorders occurred in a small percentage of men.

Here is a general summary of incidence rates from various studies:

Adverse Event	Incidence Rate (Finasteride)	Notes
Erectile Dysfunction	~2% to 4%	This is the most common sexual side effect reported.
Decreased Libido	~2% to 5%	The impact on sex drive is another frequently cited concern.
Ejaculation Disorder	~2% to 7%	Primarily a decrease in semen volume due to the drug's effect on the prostate.

Importantly, studies also show that for many men who did experience these side effects, the issues resolved either after stopping the drug or, in some cases, even while continuing therapy.

Addressing concerns about “post-finasteride syndrome”

In recent years, concerns have been raised about a condition referred to as “post-finasteride syndrome” (PFS). This term describes the experience of some patients who report that adverse effects, particularly persistent sexual dysfunction, depression, and cognitive issues ("brain fog"), continue long after they have stopped taking the medication.

These reports have led to significant discussion within the medical community and among patients. Some men have reported that these symptoms, including suicidal ideation, have had a devastating impact on their mental health and quality of life. The persistence of these symptoms is a serious concern.

Currently, PFS is not a universally recognized medical diagnosis, and research is ongoing to better understand its potential causes, true incidence, and whether a definitive causal link to finasteride exists. While reports of persistent symptoms appear to be rare, the possibility is acknowledged in the drug's official product information in many countries.

How risks compare to benefits

Deciding whether to take finasteride involves weighing its proven benefits against its potential risks. This is a personal calculation that should be made in consultation with a healthcare provider who understands your health profile and quality of life goals.

For the vast majority of men, finasteride is an effective and well-tolerated treatment. The benefit of halting hair loss and potentially regrowing hair can significantly improve self-confidence and well-being. For these patients, the low statistical risk of reversible side effects is a worthwhile tradeoff.

However, the potential for persistent sexual or psychological side effects, though seemingly rare, is a serious risk that cannot be ignored.

Benefit: Highly effective at stopping hair loss progression.
Risk: Small chance of sexual side effects, most of which are reversible.
Benefit: Can improve hair density and thickness.
Risk: Rare reports of persistent side effects ("PFS") and mood changes.

Ultimately, the key is making an informed decision. Understanding both sides of the equation allows you to choose a path that feels right and safe for you.

FDA Alert — compounded topical finasteride risks (no FDA-approved topical)

In 2025, the FDA issued an alert warning about compounded topical finasteride products. While oral finasteride is FDA-approved, no topical version has been approved for safety or effectiveness. Many telemedicine platforms and compounding pharmacies market unregulated formulations, which may carry the same systemic risks as oral finasteride, including sexual and psychological side effects. Variations in potency and purity also raise safety concerns.

FDA’s stance on compounded topical finasteride

In 2024, the U.S. Food and Drug Administration (FDA) issued an alert to healthcare providers and consumers about the potential dangers of compounded topical finasteride. The agency's stance is clear: since these products are not FDA-approved, it has not evaluated their safety, effectiveness, or manufacturing quality.

The FDA has received dozens of reports of adverse events from consumers using these products. The reports describe side effects consistent with those of oral finasteride, including erectile dysfunction, depression, anxiety, and suicidal ideation. Alarmingly, many of these side effects were reported to persist even after discontinuing the topical product.

Furthermore, the FDA noted that some consumers were told by prescribers that topical formulations carried no risk of side effects, which is untrue. The agency emphasizes that absorption through the skin into the bloodstream is expected, leading to systemic exposure and potential risks.

Why no FDA-approved topical version exists yet

The reason there is no FDA-approved topical finasteride is straightforward: no company has successfully completed the rigorous process required for approval. For a drug to gain FDA approval, it must undergo extensive clinical trials to prove both its effectiveness and its safety for a specific use. This includes determining the correct dosage, understanding its absorption, and documenting all potential side effects.

Compounded drugs bypass this entire process. They are mixed in a pharmacy for an individual patient and are not subject to the same level of scrutiny. The FDA has not evaluated compounded topical formulations of finasteride for their quality, purity, or stability.

Without this official review, there are no guarantees about what you are actually getting. The concentration of the active ingredient can vary, and the base formula could affect how much is absorbed into your bloodstream. This lack of standardization and oversight is a key reason why an approved version does not yet exist.

Risks of unregulated compounded products

Using unregulated compounded topical finasteride products comes with a unique set of potential risks beyond those associated with the FDA-approved oral tablets. Because these products are not standardized or reviewed by the FDA, you are exposed to several uncertainties and dangers.

The FDA alert specifically highlights that consumers have reported being unaware of the potential adverse effects, believing the topical route was completely safe. This misinformation can lead to serious consequences.

Key risks of these products include:

Systemic Side Effects: Skin absorption can lead to sufficient blood levels of finasteride to cause the same sexual and psychological side effects as the oral pill, including erectile dysfunction, decreased libido, and depression.
Local Skin Reactions: Users may experience local irritation, redness, dryness, stinging, or burning at the application site.
Inconsistent Dosing: The strength and purity of compounded products can vary, meaning you may get a higher or lower dose than intended.
Risk of Exposure to Others: Unlike coated oral tablets, topical solutions pose a greater risk of accidental transfer to others through skin contact, which is especially dangerous for pregnant women.

Emerging research on topical finasteride

Despite the FDA’s warning about current compounded products, the medical community remains interested in the potential of a safe and effective topical formulation of finasteride. The goal of such a product would be to deliver the therapeutic effects of blocking DHT locally in the scalp while minimizing systemic absorption and the risk of side effects.

Researchers are actively exploring various topical formulations in clinical studies to find this balance. You can search for these studies on platforms like Google Scholar to see the progress being made. Early-stage research has shown some promise, suggesting that certain formulations can increase hair count with significantly lower levels of finasteride in the bloodstream compared to the oral pill.

However, it is important to distinguish this ongoing research from the unregulated products currently on the market. Until a product successfully completes large-scale clinical trials and receives FDA approval, its safety and efficacy remain unproven.

Who should avoid it / precautions (pregnancy exposure warning)

Illustration highlighting safety considerations and FDA warnings for finasteride treatment

While finasteride is a valuable tool for many, it is not suitable for everyone. Certain patients should avoid using or even handling the medication due to serious potential side effects. The most critical precaution relates to pregnancy, as exposure can cause severe harm to a developing fetus.

It is also important for people with underlying health conditions to discuss the risks with their doctor. In the next sections, we will detail these contraindications and safety considerations to help you understand who should steer clear of finasteride.

Women who are pregnant or may become pregnant

The strongest warning for finasteride use relates to women who are pregnant or may become pregnant. The medication is classified as Pregnancy Category X, meaning that studies in animals or humans have demonstrated fetal abnormalities and the risk of use in pregnant women clearly outweighs any possible benefit.

Finasteride can cause abnormalities of the external genitalia of a male fetus if a pregnant woman is exposed to it. This is because it inhibits the conversion of testosterone to DHT, a hormone crucial for the normal development of male reproductive organs.

Because of this risk, these women should not take finasteride. They should also not handle crushed or broken finasteride tablets or come into contact with topical formulations. The active ingredient can be absorbed through the skin, posing a direct threat to the pregnancy. Any woman who comes in contact with finasteride during pregnancy should be counseled about the potential hazard.

Handling crushed tablets: safety considerations

The safety precautions for finasteride extend to how the medication is handled. FDA-approved oral finasteride tablets are coated. This coating serves as a protective barrier, preventing contact with the active ingredient during normal handling. This is a crucial safety feature, especially in households where women of childbearing age may be present.

However, if a tablet is broken or crushed, this protective barrier is lost. This creates a risk of finasteride being absorbed through the skin of anyone who handles it. This is the primary reason why pregnant women are advised not to handle broken tablets.

This same risk applies to compounded topical finasteride, which has no protective coating. An allergic reaction or other adverse event could occur from skin contact. Proper handling of the medication is a key part of using it safely and preventing an accidental adverse event for others.

Men with liver disease or certain health conditions

Before starting finasteride, it is essential to share your complete medical history with your health care provider. The drug is extensively metabolized in the liver by the CYP3A4 enzyme system. For this reason, caution should be exercised when prescribing finasteride to men who have a history of liver disease or impaired liver function.

While no specific dose adjustments are listed on the manufacturer's label for hepatic impairment, a compromised liver may not process the drug as efficiently, potentially leading to higher concentrations in the body and an increased risk of side effects.

Your doctor needs to evaluate your overall health to determine if finasteride is a safe option for you. Openly discussing your medical history is the first step in ensuring that the treatment benefits outweigh the potential risks for your specific situation.

Monitoring & follow-up

Starting finasteride is not a one-time decision; it's the beginning of a long-term treatment plan that requires ongoing monitoring and follow-up. Working closely with your healthcare provider is essential to track your progress, manage any side effects, and ensure the therapy remains safe and effective for you.

Regular check-ins allow your doctor to assess changes in hair density and discuss your experience with the medication. This partnership is key to achieving the best possible outcome while prioritizing your health.

When to schedule follow-up with your clinician

Establishing a regular follow-up schedule with your healthcare provider is a critical part of a safe finasteride treatment plan. According to guidelines from the American Urological Association (AUA) for patients using finasteride for BPH, monitoring after 3 to 6 months of starting treatment is recommended. This timeline is also a good benchmark for those taking it for hair loss.

Your first follow-up appointment, typically around the 3-to-6-month mark, allows your clinician to assess your initial response to the therapy. It’s an opportunity to discuss any side effects you may be experiencing and for your doctor to answer any questions you have.

After that initial check-in, an annual follow-up is generally a good practice. This allows you and your doctor to review long-term efficacy, monitor for any new health concerns, and make an informed decision about continuing the therapy. The medical community stresses the importance of this ongoing dialogue.

What labs (if any) may be ordered

For men taking finasteride for hair loss, there are no specific, routine labs that are universally required for monitoring. Most of the follow-up process relies on discussing your progress and any side effects you may be experiencing. However, there is one lab test that is important to be aware of: the prostate-specific antigen (PSA) test.

The PSA test is used to screen for prostate issues, including prostate cancer. Finasteride is known to lower serum PSA levels, typically by about 50% after 6 to 12 months of use. Because of this, it is recommended to get a baseline PSA level before starting therapy.

Your doctor will need to be aware that you are taking finasteride when interpreting any future PSA results. Often, they will double the measured value to get a more accurate approximation. This is crucial for proper prostate health surveillance.

Tracking progress with photos and hair density scores

Since hair growth is a slow process, tracking your progress objectively can help you and your doctor assess the effectiveness of the treatment. One of the simplest and most effective ways to do this is by taking standardized photographs. This creates a visual record of your hair density over time.

This method helps manage expectations and provides concrete evidence of any changes, which can be highly motivating and improve your quality of life. For best results, follow a consistent process.

Here’s how you can effectively track your progress:

Establish a Baseline: Take clear, well-lit photos of your scalp from multiple angles (front, top, crown, sides) before you start treatment.
Use Consistent Lighting and Angles: When taking follow-up photos every 3-6 months, try to replicate the same lighting, angles, and hair length.
Compare Over Time: Compare your photos at the 6-month, 12-month, and annual marks to your baseline images to see changes in hair count and coverage.
Professional Assessment: Some clinics use tools to measure hair density scores for a more quantitative assessment.

Talk to a Healthon clinician to choose a safe plan

Consult a Healthon clinician to create a personalized finasteride plan. Our medical team provides evidence-based guidance, monitors safety, and helps you achieve optimal results with ongoing support.

However, it's important to be aware of potential side effects, especially the recent 2025 FDA alert regarding compounded topical finasteride and its possible links to sexual dysfunction. Regular monitoring of your health and open communication about any adverse reactions will empower you to make an informed decision tailored to your needs.

Why self-medication is risky

Attempting to treat hair loss on your own by ordering medication online without a proper medical consultation is incredibly risky. Self-medication with finasteride exposes you to significant dangers, as you bypass the critical safety checks that a healthcare provider performs.

Without a professional evaluation, you may miss crucial contraindications based on your medical history or other medications you take. As the recent FDA alert on compounded topicals showed, many consumers were unaware of the potential for serious adverse effects because they weren't properly counseled. Making an informed decision is impossible without a doctor's guidance.

The risks of self-medication include:

Receiving unregulated or counterfeit products.
Missing a correct diagnosis for your hair loss.
Failing to understand the full range of potential side effects.
Lacking a plan for monitoring your health during treatment.

Personalized treatment options (oral, topical, combo)

There is no one-size-fits-all solution for hair loss. A consultation with a clinician allows for the creation of a personalized treatment option tailored to your specific needs, goals, and risk tolerance. Your doctor will consider factors like the extent of your hair loss, your medical history, and your lifestyle.

Based on this evaluation, your provider can discuss the different approaches. They can explain the well-documented efficacy and risks of an FDA-approved oral finasteride treatment. They can also provide crucial context on the unapproved status and reported dangers of compounded topical finasteride, helping you understand why caution is warranted.

In some cases, a combination therapy, such as using finasteride with topical minoxidil, may be recommended to tackle hair loss from multiple angles. This personalized strategy, guided by professional expertise, gives you the best chance of achieving your desired results safely.

Next steps for starting safe evidence-based therapy

If you are ready to take control of your hair loss, the path to starting a safe, evidence-based therapy is clear and straightforward. The first and most important step is to move away from anonymous online sources and engage with a professional healthcare provider who can offer expert guidance.

Your next steps should involve a structured consultation. During this meeting, be prepared to openly discuss your hair loss concerns, your goals for treatment, and your complete medical history. This honest dialogue is the foundation for a safe treatment plan.

Based on this conversation and the latest clinical studies, your clinician will help you weigh the risks and benefits of finasteride. Together, you will decide on the most appropriate therapy, establish a plan for monitoring your progress and health, and begin your journey with confidence and professional support.

Frequently Asked Questions

Is topical finasteride safer than oral?

Not necessarily. While some believe topical finasteride has fewer side effects, the FDA has warned that it can be absorbed into the bloodstream and cause the same adverse effects as oral finasteride. Since topical products are unregulated and not FDA-approved, their dosage, purity, and overall safety are unverified, posing unique risks.

What happens if I stop finasteride?

If you stop taking finasteride, your body’s DHT levels will return to their normal baseline within about two weeks. Consequently, the hair loss process that was halted will resume. Any hair growth you gained or preserved while on the medication will likely be lost within 12 months of discontinuation.

Do sexual side effects from finasteride go away?

For most men who experience sexual dysfunction, the side effects are reversible and often resolve after stopping the drug. Some studies show they can even disappear during continued use. However, there are reports of persistent sexual dysfunction that continues after discontinuing finasteride, a concern known as "post-finasteride syndrome."

Can finasteride be combined with minoxidil?

Yes, finasteride can be safely combined with minoxidil to enhance hair loss treatment. This combination may provide improved results by addressing different aspects of hair regrowth. However, it's essential to consult a healthcare professional for personalized advice and monitoring during the treatment.

How long before I see results with finasteride?

Results with finasteride typically appear within three to six months of consistent use. However, individual responses may vary based on factors such as dosage and personal health. It's essential to consult your healthcare provider for personalized expectations and guidelines.
