Want to emulate Jason Momoa’s full beard or Ben Affleck’s well-groomed quintessential cool guy look? Hollywood stars make it look easy, but the truth is that not all men can grow thick beards. Maybe you’ve heard about Minoxidil, the popular FDA-approved hair loss drug. But does it only regrow hair on the scalp, or is Minoxidil used for beard growth as well? 


If you’re looking to warm your face with a full beard, you might consider using Minoxidil for beard growth. But before investing your hard-earned time and money, you want a solid answer to your question: will Minoxidil work for my beard?


Maybe. But the research to support it is thin. Clinical trial findings showcase Minoxidil’s effectiveness like Russian roulette. The drug shows minimal to no results for some and significant results for others. And most published studies on Minoxidil focus on scalp hair regrowth, sometimes citing facial hair regrowth as a side effect of more potent solutions (3-5% Minoxidil). Only a handful of studies specifically examine the drug’s effects on beard regrowth (more on those later). 


Here at Daniel Alain, we have a team of dedicated dermatologists and scientists conducting the most up-to-date research on hair loss solutions, including Minoxidil. That’s why we created our Minoxidil Response Test (MRT) — to give you control and help you know right away if Minoxidil will work for you. 


So, will Minoxidil work for your beard? Perhaps. But before you try it out, you need more answers. Keep reading.

How Does Minoxidil Work For Facial Hair?

First thing’s first: is Minoxidil used for beard growth? Technically, the FDA approved the drug for scalp hair regrowth, not facial hair. But that doesn’t mean you can’t soak up some off-label benefits. 


Before you consider Minoxidil for growing a thicker beard, remember: it’s considered off-label use. In other words? Use at your own risk. 

What the science says about Minoxidil for beard growth 

Most clinical studies notice facial hair regrowth as a side effect. Meaning? The drug’s beard effects aren’t well studied, but even some beard growth may be good news for those wanting more facial hair.


Both oral and topical Minoxidil can cause hypertrichosis (excessive body hair growth). Doctors also noticed facial hypertrichosis as a side effect for study participants taking both the 2% and 5% solutions (but especially the more potent 5% solution). 


So, how does Minoxidil work its magic on beards? Minoxidil may speed up the hair growth cycle to the anagen (growth) phase and extend it. The result? More hair and thicker hair. 


Minoxidil opens up potassium channels in your muscle cells. This strengthens and improves the chance of stronger hair follicles for your scalp — but, as it turns out, also your body and face. 


A greater Minoxidil concentration is more likely to lead to facial hair growth.  


Let’s walk through a couple of study findings that measure Minoxidil’s direct effects on facial hair regrowth. 


One study explored how effective 3% Minoxidil was at growing beards for Thai men versus a placebo (sugar pill). After about four months of twice-daily application, participants saw progressive beard growth. Another study found that Minoxidil’s 5% solution caused significant hair growth in the beard, eyebrows, fingers, and chest areas after three months. 


These studies may indicate that using Minoxidil for beard growth may show results, but without a doubt, more research is needed. But, early results may be promising enough to encourage many to apply the drug to their face. Just remember that there is no guarantee it’ll work. 


Does it seem worth a shot? Keep reading for the steps you’ll need to take. 



How to Use Minoxidil for Beard Growth

Before you use Minoxidil for beard growth, we recommend you do the following:

  • Consult your doctor.
  • Prepare for any possible side effects (redness, irritation, and itching).
  • Recognize that this mode of treatment is considered off-label use.
  • Order the Minoxidil Response Test to determine if Minoxidil will work for you.


After all that, you’re ready to apply Minoxidil to your beard. 

  1. Purchase Minoxidil, either the popular Rogaine® brand version, or others like Keeps and Hims. 
  2. Use the stronger 5% solution to increase the chances of beard growth. 
  3. Follow the instructions and apply the indicated dosage to your beard area. 
  4. Apply once or twice daily, depending on the instructions, for a minimum of four months. 
  5. Consult your doctor if you notice any side effects like redness, rashes, or itching. 


Now, we wait. But you might ask yourself: how do I know if Minoxidil is working?



How Long Does it Take to See a Fuller Beard?

You’ve applied Minoxidil religiously to your chin for that dream goatee. After a few days of applying, you might wonder: will Minoxidil work for me? If you take the Minoxidil Response Test and learn that you have the SULT1A1 enzyme activity, you may see the first results around three months. But generally, Minoxidil takes 6-9 months to show the best results on the scalp. 


But does that timeline align with using Minoxidil for beard growth?


We can’t be sure. There hasn’t been enough investigation into Minoxidil’s direct effects on beard growth. We can look at existing beard-specific studies as a baseline. The two studies we mentioned show that participants experienced notable results after three and four months. 


During that waiting period, you might notice an unsavory side effect: more hair loss. Don’t worry; this is a common sign that the treatment is working and only lasts 2-4 weeks. But if the shed persists beyond a month, pause treatment and consult your doctor. 



Does Minoxidil Work for Everyone?

Unfortunately, Minoxidil won’t work for everyone. As dedicated hair experts, we’re well-versed in Minoxidil and how it affects our clients differently. That’s why we conducted years of meticulous research to discover precisely why the drug gives some people hunky, Johnny Depp locks, and others, well, nothing. 


Here’s the catch with Minoxidil: We found that Minoxidil users experienced successful results only if they had SULT1A1 enzyme activity in their scalp. Those without this enzyme could wait up to one year just to find out that Minoxidil didn’t work for them. 


Even if you have the enzyme activity, you could still wait 6-9 months to see results. Our opinion? That’s too long to wait unless you know for sure that a strapping beard awaits you at the end of those unnerving months. Currently, the MRT is the quickest way to find out if Minoxidil will work for you.



Is There an Enzyme Booster to Activate Minoxidil?

Don’t have the right enzyme activity to activate Minoxidil? You still have options. Our latest research development has been to perfect our unique SULT1A1 enzyme booster, a product that gives you a prime scalp environment for Minoxidil to work its magic. Stay tuned as we roll out this exciting breakthrough!

Frequently Asked Questions About Minoxidil

How Effective is Minoxidil for Beard Growth?

Minoxidil’s effectiveness for beard growth hasn’t been studied as extensively as its effects on scalp hair regrowth. However, early studies indicate that it promotes facial hair regrowth more than a placebo treatment, especially in higher potencies (3-5%). 

Is it Safe to Use Minoxidil on Facial Hair?

Minoxidil is only FDA-approved as a treatment for hair loss on the scalp, not beard regrowth. However, consistent side effects of facial hypertrichosis have led to growing popularity in using the drug for facial hair regrowth. Minoxidil has several known adverse effects, including contact dermatitis, which can occur if you use the treatment on your face. 


More studies are needed to determine if Minoxidil is truly safe as a facial hair regrowth solution. 

Who Should Avoid Using Minoxidil for Beard Growth?

Doctors advise against using Minoxidil if you have any of the following:

  • Pheochromocytoma (adrenal gland tumor)
  • Heart failure
  • Angina
  • Epilepsy


If you have any other diagnoses, consult your doctor before taking Minoxidil. 

What are the Side Effects of Using Minoxidil for Beard Growth?

Minoxidil is known to have the following adverse effects for some users: 

  • Hypertrichosis (hair growth on the face, chest, back, arms, legs, etc.)
  • Contact dermatitis (skin rashes)
  • Skin irritation and redness (erythema, etc.)
  • Shedding
  • Isolated pruritus (itchy skin)

Should I Use Minoxidil on My Beard?

If you discover you have the right enzymes to respond to Minoxidil, it may be worthwhile to try it for beard growth. Minoxidil isn’t the right hair loss solution for everyone. Before using Minoxidil for beard growth, consider the risks and consult your doctor. 

Does Minoxidil Make Your Beard Thicker?

Minoxidil caused greater hair density (thickness) in the facial area in some clinical study participants. 

Which Minoxidil is Best for Beard Growth?

Researchers find that 3% and 5% Minoxidil solutions are most effective in promoting facial hair regrowth because of their high potency.

Does Minoxidil Age Your Face?

There aren’t any clear studies that suggest Minoxidil ages your face. However, some adverse side effects like redness and rashes could alter your appearance. 

Can You Leave Minoxidil on Overnight for Beard Growth?

Doctors and brand-name Minoxidil providers don’t recommend leaving topical Minoxidil on your body for more than four hours. Leaving it on overnight could perpetuate side effects and cause irritation or skin rashes.

What Else Works for Beard Growth?

While hair density is often genetic, there are other ways to promote beard enhancement. You could try introducing more hair-growth-promoting vitamins to your diet, like biotin, B-12, and niacin. 

Where Can I Buy Minoxidil for Facial Hair?

Several companies sell hair loss solutions with Minoxidil as the primary ingredient, like Rogaine, Keeps, Hims, and Kirkland. However, none of them indicate their product as being primarily for facial hair. 

How Much Does Minoxidil Testing Cost?

Daniel Alain’s Minoxidil Response Test for men costs $139.00. 

Where Can I Get a Minoxidil Response Test?

You can order an MRT online from Daniel Alain.
