When it comes to tackling male pattern hair loss, finasteride and minoxidil are two of the most popular and effective treatments available.
While both are backed by years of research, they work in different ways, are used differently, and cater to slightly different needs.
Sometimes you’ll use one or the other, but they can be used together too. But you need to understand them before you start taking them, so let’s get right into the detail. We’ll compare finasteride against minoxidil, dive into the main differences, and explain the realistic expectations you need when using either drug for hair growth.
What is Finasteride?
Finasteride is a drug used to treat hair loss caused by male pattern baldness, which is the most common type of hair loss in men. You take it orally as a tablet.
It works by reducing the levels of a hormone called dihydrotestosterone (DHT) in your scalp. DHT is what causes hair follicles to shrink over time, leading to thinning hair and eventual hair loss.
By lowering DHT levels, finasteride helps slow down hair loss and can even encourage regrowth in areas where the follicles are still active.
Since finasteride works by affecting hormones, it’s a prescription-only treatment in the UK. This means you’ll need to speak to a doctor or pharmacist, although online services now make it much easier with virtual consultations and home delivery options.
Finasteride works best if you start using it early on in the hair loss process because it can’t revive follicles that have completely stopped working.
Finasteride Cost
The cost of finasteride can vary depending on whether you opt for a branded version like Propecia or a generic equivalent.
Generic finasteride is more affordable, typically costing between £15 and £50 per month, while branded options are at the higher end of the range. That’s despite them being no more effective than the generic versions.
Online subscription services often provide competitive prices and can be more convenient, offering monthly plans that include virtual consultations and delivery.
Just be careful to make sure you’re buying from a reputable source.
Timeframe for Results
Finasteride isn’t an instant solution. Most users start to see improvements in hair thickness and reduced shedding after about 3–6 months, with maximum results typically achieved after a year of consistent use.
What is Minoxidil?
Minoxidil is a topical treatment for hair loss that you apply directly to your scalp. It’s commonly used to treat male and female pattern baldness, as well as other types of thinning hair.
It works by improving blood flow to the scalp. Minoxidil is a vasodilator, meaning it helps widen blood vessels. This increased circulation delivers more oxygen and nutrients to the hair follicles, which can strengthen thinning hair and stimulating hair growth.
Unlike finasteride, minoxidil doesn’t affect hormones, so it’s available over the counter in the UK. You don’t need a prescription, and you can easily find it in pharmacies, supermarkets, or online.
Consistency is key with minoxidil. It’s applied to the scalp once or twice daily, depending on the product, and you need to keep using it to maintain results. If you stop, hair loss will likely resume.
Minoxidil is most effective when used early in the hair loss process and works particularly well on thinning at the crown. It’s less reliable for receding hairlines, and results can vary depending on the individual.
Just to note, you can get oral minoxidil, but usually it’s a topical solution that’s provided. If you prefer oral medication then it’s worth asking though it can result in systemic side effects. Always consult a healthcare professional to understand the key differences between the two types.
Minoxidil Cost
Minoxidil is generally one of the more affordable and accessible hair loss treatments, with prices ranging from £10 to £30 per month depending on the product’s concentration (2% or 5%) and whether it’s a branded or generic version.
Foam formulations tend to be slightly more expensive than liquid ones, but both work similarly. As it’s available over the counter, you can shop around for the best deals in pharmacies, supermarkets, or online.
Timeframe for Results
Minoxidil also requires patience. It can take 4–6 months of daily application to see noticeable improvements, with shedding often occurring in the first few weeks as weaker hairs fall out to make way for new growth.
Effectiveness for Women
Minoxidil is one of the few proven treatments for female pattern hair loss.
Women typically use the 2% solution, though some may benefit from the 5% formula if prescribed. It’s important to note that finasteride isn’t commonly prescribed for women due to potential risks, especially during pregnancy.
Finasteride vs Minoxidil – Which is More Effective?
Both finasteride and minoxidil are proven treatments for male pattern hair loss, but their effectiveness can vary depending on the type and stage of hair loss, as well as the individual using them.
While both have been shown to deliver results and promote hair growth, they work in different ways, making them more suitable for certain situations – and they’re often even more effective when used together.
Finasteride Success Rates
Finasteride is highly effective for treating male pattern baldness, particularly on the crown and the mid-scalp.
Medical studies have shown that it slows or stops hair loss in about 90% of men, with around 65% experiencing noticeable regrowth after consistent use over 12 months. This makes it one of the most reliable treatments for combating hair loss caused by DHT.
However, finasteride works best when it’s started early in the hair loss process. It can preserve and strengthen existing hair, but it won’t revive follicles that have already become dormant.
This is why men experiencing thinning or mild balding tend to see the most success, while those with more advanced hair loss may see limited results.
Minoxidil Success Rates
Minoxidil is slightly less predictable in its results. Studies suggest that 40–60% of users see improvements in hair density, thickness, or reduced shedding, though the timeline for visible changes can vary widely.
Minoxidil is most effective on thinning at the crown and works well for people in the early to moderate stages of hair loss.
That said, it’s not always as effective for receding hairlines or temple areas, and individual results depend on how well the hair follicles respond to increased blood flow.
Because minoxidil isn’t targeting the hormonal cause of hair loss, its impact can be less dramatic than finasteride in certain cases. You might not notice the new hair growth as quickly or as clearly, too.
When and How to Use Them Together
Minoxidil and finasteride address hair loss from two different angles: finasteride targets DHT, the root hormonal cause, while minoxidil improves blood flow to nourish the scalp. Because they work in complementary ways, combining the two treatments can often give you better results than using either one alone.
For example, finasteride can stabilise hair loss and prevent further thinning, while minoxidil stimulates growth in areas where hair is already thin.
Many hair specialists recommend using both for men who are serious about tackling hair loss, as the combination can help preserve and regrow hair simultaneously.
Of course, the drawback to that is the long-term cost, since you’re paying for two drugs.
Long-Term Commitment and Results
It’s important to understand that both minoxidil and finasteride require a long-term commitment.
If you stop using finasteride or minoxidil, the benefits will reverse over time, and hair loss will likely resume within six to twelve months.
Lifestyle Considerations
Both treatments have unique lifestyle implications. Oral finasteride is simple to take daily and doesn’t require much effort. However, its potential hormonal side effects may deter some users.
Topical minoxidil, while non-invasive, involves applying a liquid or foam to the scalp daily. Some people find this process time-consuming or messy, and it may not suit those with sensitive skin prone to irritation.
Ultimately, finasteride is generally considered more effective for male pattern baldness, especially when used early on, while minoxidil is a great option for those looking for a non-prescription solution or for additional support alongside finasteride.
Choosing the right approach often depends on the severity and type of hair loss, and consulting with a doctor or specialist can help tailor the best treatment plan for your needs.
Where to Buy Safely
It’s crucial to purchase finasteride and minoxidil from reputable sources. For finasteride, a prescription ensures the product is genuine, while minoxidil should be bought from trusted retailers.
Be really careful when buying online – counterfeit medications can be ineffective or even harmful. Stick to licensed providers or pharmacies, and avoid products with prices that seem too good to be true.
Minoxidil and Finasteride vs Hair Transplants
Hair transplants are a permanent solution to hair loss, but they’re not always the first step for everyone.
Many people consider finasteride or minoxidil as alternatives to surgery, while others use these medications alongside a transplant to maximise their results.
Understanding how these treatments fit into the broader picture of hair restoration can help you decide what’s best for you.
Why Choose Finasteride or Minoxidil Over a Hair Transplant?
For those in the early stages of hair loss, finasteride and minoxidil are often the first line of defence. These treatments are non-invasive, affordable compared to surgery, and don’t require downtime for recovery.
They’re also effective at slowing or even halting further hair loss, which is a key goal for many people. If you just want to promote hair growth after minor losses, then hair loss medications are the best path.
A hair transplant, on the other hand, is a surgical procedure that involves moving hair follicles from one part of the scalp (usually the back or sides) to areas where hair is thinning or has been lost.
While it offers a permanent solution, it can be a significant financial investment and involves both time and commitment to aftercare. For those with mild to moderate hair thinning, finasteride or minoxidil might be sufficient without the need for surgery.
Why a Hair Transplant is Better in Some Cases
While finasteride and minoxidil can preserve hair and encourage regrowth, they have limitations.
Neither treatment can bring back hair in areas where follicles have completely stopped working or have been lost for a long time.
This is where hair transplants excel, as they physically move healthy hair follicles to balding areas, providing a permanent fix that medication alone cannot achieve.
A transplant is particularly effective for men with advanced hair loss, such as a receding hairline or bald patches, where medications may not produce significant results.
It also offers natural-looking, permanent results, especially when performed by an experienced surgeon. However, for the best outcome, many transplant patients combine their surgery with medication.
Using Finasteride and Minoxidil with a Hair Transplant
Finasteride and minoxidil are often recommended alongside hair transplants to improve and maintain results.
Surgery can restore hair in bald areas, but it won’t prevent further thinning of the existing hair around the transplanted areas. Without ongoing treatment, you could end up losing the non-transplanted hair, which may lead to uneven or patchy results over time.
Finasteride is particularly important after a transplant because it targets DHT, the hormone responsible for hair loss. By reducing DHT levels, it helps protect the native hair and prevents future shedding.
Minoxidil can also be useful for improving blood flow and supporting the growth of both transplanted and existing hair, particularly in the months after surgery when follicles are establishing themselves.
So, just be careful in making the assumption that a hair transplant is a one-off fee compared to the ongoing costs of drugs. You might still need to pay those drug costs for the long term.
Side Effects of Finasteride and Minoxidil
While finasteride and minoxidil are effective treatments for slowing hair loss, it’s important to understand the potential side effects associated with each.
Most people tolerate these treatments well, but, as with any medication, there’s a chance of adverse effects. Being informed can help you weigh the benefits against the risks and use these treatments safely.
Side Effects of Finasteride
Finasteride works by lowering levels of dihydrotestosterone (DHT), which can affect more than just hair follicles. The most commonly reported side effects are related to sexual health, though these occur in only a small percentage of users. These include:
- Decreased libido (a decreased interest in sex).
- Erectile dysfunction (difficulty achieving or maintaining an erection).
- Decreased semen volume during ejaculation.
These side effects are rare, affecting around 1–2% of men, and are usually mild.
In most cases, they resolve after stopping the medication. However, a very small number of users report longer-lasting issues even after discontinuing treatment, a condition sometimes referred to as post-finasteride syndrome.
This is still a topic of debate in the medical community, but it’s important to be aware of.
Other possible but less common side effects include mood changes, such as mild depression or anxiety, and in very rare cases, breast tenderness or enlargement.
Women, especially those who are pregnant or may become pregnant, should avoid handling finasteride tablets, as the drug can harm a developing male foetus if absorbed through the skin.
Side Effects of Minoxidil
Minoxidil is applied topically, so its side effects are generally limited to the areas where it’s used. The most common issues are related to skin irritation, including:
- Itching, redness, or dryness on the scalp.
- Flaking or dandruff-like symptoms, particularly with the liquid form of minoxidil.
In some cases, minoxidil can cause excessive hair shedding in the first few weeks of use. This can be alarming, but it’s usually a temporary “shedding phase” as weaker hairs fall out to make way for stronger growth.
Rarely, minoxidil can cause unwanted hair growth in other areas, such as the face, if the product spreads beyond the scalp during application. This is more likely if the medication isn’t applied carefully or if you use too much.
Some users report headaches, dizziness, or a rapid heartbeat when using minoxidil, although this is uncommon. If these symptoms occur, it’s important to stop using the product and speak to a doctor.
Managing Side Effects and Staying Safe
For both treatments, side effects are usually mild and manageable. If you experience any symptoms, speak to your doctor – they may recommend adjusting your dosage or switching to a different product.
Using finasteride or minoxidil correctly, as instructed by your doctor or the product packaging, can also minimise risks.
In some cases, combining treatments (such as finasteride and minoxidil) can help you achieve better results while using lower doses of each, potentially reducing the chance of side effects. However, always consult a specialist before starting or combining treatments.
Alternatives and Complements
Beyond finasteride and minoxidil, there are some other treatments you may wish to consider. Low-level laser therapy (LLLT) devices, such as laser caps or combs, can stimulate hair follicles and improve circulation. Ketoconazole shampoos, like Nizoral, can help reduce scalp inflammation and support healthier follicles. While not a cure, dietary supplements like biotin and zinc can provide additional hair health support.
Before-and-After Tracking
If you’re starting treatment, it’s a good idea to take clear photos of your hair before you begin.
Tracking progress over several months can help you see subtle changes that might otherwise go unnoticed.
This is especially useful with finasteride and minoxidil, where improvements can take time to appear.
Which Option is Right for You?
The decision between medication, a hair transplant, or a combination of both depends on a wide range of factors, including the stage of your hair loss, your budget, and your goals.
Medications like finasteride and minoxidil are often the first step and can be enough for early or moderate hair thinning. They’re also essential for maintaining results after a transplant.
And it’s not always finasteride vs minoxidil. Using both is often better for not only treating the causes, but encouraging the hair growth cycle.
A hair transplant, on the other hand, is the best option for restoring lost hair in areas where medications can’t help, such as bald patches or severe thinning. However, for long-term success, most transplant patients will still need to use finasteride or minoxidil to preserve their remaining hair and protect the investment they’ve made in surgery.
Ultimately, consulting with a specialist can help you create a personalised plan to achieve and maintain the best possible results, whether you’re looking for hair regrowth via the use of minoxidil and finasteride, or whether a transplant is better.
