Should You Use Finasteride and Minoxidil Together for Hair Loss?

Key Takeaways 

• Finasteride and minoxidil work in different ways, which means they can complement each other and may be more effective when used together.

• Several studies show that using both treatments together can lead to better hair regrowth and density than using just one.

• Being consistent is key, and side effects are possible with both medications. 

Hair loss can be unsettling for many men, especially after trying different treatments without success. You may have heard of finasteride and minoxidil or even tried one of these FDA-approved options. You might even be asking whether you can take finasteride and minoxidil together for hair loss.

It’s possible and often recommended to take finasteride and minoxidil together for the best results. Since they work differently, they can help manage hair loss from multiple angles. And that’s not without research to support the effectiveness of the two. Although you can use both medications, the question comes down to whether it makes sense for your situation. 

What is Finasteride?

Finasteride is a prescription drug that works by blocking an enzyme called 5-alpha reductase. This enzyme helps convert testosterone into dihydrotestosterone (DHT), a hormone involved in shrinking hair follicles in those with male pattern baldness.

Taking finasteride can help decrease DHT levels to slow down hair loss. In many cases, it can allow the scalp to regrow hair. As one of the oldest and most effective hair-loss drugs, finasteride was found in some studies to improve hair growth in almost 50% of men after the first year of treatment and over 60% of men by their second year.

Finasteride Dosage and Precautions

Finasteride is typically taken as a 1 mg pill by mouth once daily. It’s also prescribed at a higher dose for benign prostatic hyperplasia (BPH), or an enlarged prostate. 

Potential side effects of finasteride include:

• Decreased sex drive 

• Erectile dysfunction (ED)

• Problems with ejaculation

• Breast enlargement or tenderness

• Rash

Finasteride is not approved for women or children with hair loss. It may cause problems in an unborn baby and should never be handled by women who are pregnant.

What is Minoxidil?

Minoxidil is a topical medication that you apply directly to the scalp. It was originally used as a drug for high blood pressure until healthcare providers started noticing that patients had increased hair growth as a side effect. This side effect was seen in different parts of the body, not just the head. 

Minoxidil works by widening the blood vessels, which increases blood flow to the hair follicles. As a result, minoxidil helps the hair follicles stay in a growth phase for a longer period. Over time, it may also help increase the size of the hair follicles. 

Minoxidil Dosage and Precautions

Minoxidil comes as a liquid or foam in 2% or 5% strengths. It’s typically applied twice daily, although some people might use it once daily, especially if they’ve been on it for a long time.

Potential side effects of minoxidil include:

• Scalp irritation or redness

• Facial hair growth, which may be a concern for women

• Shedding when first starting treatment

Ask a doctor or healthcare provider about using minoxidil if you have a history of heart disease. While minoxidil is used topically for hair loss, a small amount may enter the bloodstream, which could lead to cardiovascular effects. 

Can Finasteride and Minoxidil Be Combined?

Yes, using finasteride and minoxidil together is a treatment option for many men with androgenic alopecia. In fact, they’re often recommended as a combination treatment since they work in different ways. That means they can work synergistically to manage male pattern baldness.

Finasteride helps with the root cause of hair loss, while minoxidil helps preserve and stimulate the hair follicles directly. In other words, finasteride can prevent further damage, while minoxidil can help induce regrowth.

The Research Behind Combining Finasteride and Minoxidil

Studies have shown that combining finasteride and minoxidil may be more effective than using either medication alone. A few studies have formed the basis for using finasteride and minoxidil together. 

2020 Systematic Review and Meta-Analysis

One meta-analysis looked at five randomized controlled trials comparing combination therapy with using either drug alone. Patients using finasteride and topical minoxidil together had higher improvement scores (P < 0.00001) than those on monotherapy. Side effects were similar between the groups, with no significant increase in adverse events.

2022 Network Meta-Analysis Comparing Treatment Options 

Another analysis included 23 studies comparing different hair loss treatments. At 48 weeks, 1 mg per day of finasteride showed the greatest increase in terminal hair count, significantly outperforming both 2% and 5% topical minoxidil (mean differences of 32.1 and 26.2 hairs/cm², respectively). This study solidified finasteride as a key part of combination therapy.

2025 Network Meta-Analysis on Combination Therapies

A 2025 study evaluated 20 different treatment combinations involving minoxidil. For men, finasteride combined with minoxidil ranked highest among all treatment options with a SUCRA value of around 80%. SUCRA shows how well a treatment performs compared to others, with higher numbers meaning better overall results. Combining finasteride and minoxidil also showed an average increase in hair density of around 35 hairs/cm² compared to minoxidil alone.

Because of the evidence behind using finasteride and minoxidil together for hair loss, many dermatologists may recommend them together as a first-line treatment. While results can vary, these studies are worth taking into account.

Who is Combination Treatment For?

Not everyone needs to use both treatments right away. However, combination therapy might make sense if:

• You've tried one treatment alone without seeing much improvement

• Your hair loss is moderate to severe

• You want to maximize your chances of regrowth

• You're able to commit to a consistent routine

• You've discussed the option with a healthcare provider

On the other hand, some people may prefer to start with one treatment and add the other later if needed. There's no one-size-fits-all method, and what works best for one person might not be appropriate for someone else. Your budget and personal preferences also come into play.

Bottom Line

Finasteride and minoxidil are both effective treatments for hair loss that may work better when used together. Finasteride treats the hormonal cause of hair loss, while minoxidil increases blood flow to directly stimulate the hair follicles. Although research shows that taking finasteride and minoxidil together is a viable option, both medications may come with potential side effects.

Keep in mind that these medications are meant to be used long-term on a consistent basis. Stopping these treatments could cause hair loss to return. In any case, it’s best to consult a healthcare provider for the best option.
