Is minoxidil safe for beard growth?

Minoxidil is a popular product that is most commonly used to combat male and female pattern baldness, but is also gaining steam for its use in growing a beard.

Because it is becoming more popular by men looking to grow a beard, we must review what the literature has to say about the safety of using minoxidil for beard enhancement.

Let us try to answer the question, “Is minoxidil safe for beard growth” as conclusive as possible.

Is minoxidil safe for beard enhancement? Literature review

Currently, not a lot of studies have been performed about the safety of rubbing topical minoxidil on the face for beard enhancement.

Yet, the following studies, countless other anecdotes being told by previous topical minoxidil users, myself included, state that using topical minoxidil for beard enhancement is safe and effective in most cases while reporting only minimal side effects.

This particular study is favorable and concludes the following:

Side-effects were evaluated by detailed history
and physical examination. The adverse reactions were mild and not statistically significantly different between groups.

In conclusion, minoxidil 3% lotion is effective and safe for beard enhancement.”[1]

To be fair, it should be noted that the study had only 48 participants, and 46 finished the study. More studies with a larger amount of participants are needed to confirm the safety of minoxidil for beard enhancement.

I personally noted only very mild adverse effects when using topical minoxidil for beard growth, like dried out skin (when taking liquid minoxidil.)

Another study expressing its approval states the following:

Hundred patients with AA classified into five groups of 20 treated with: Group I, latanoprost 0.1% lotion; Group II, minoxidil 5% lotion; Group III, betamethasone valerate 0.1% solution; Group IV, combination of latanoprost lotion and betamethasone valerate solution and Group V, a vehicle lotion control group.

Latanoprost, minoxidil and betamethasone valerate are effective and safe in the treatment of patchy AA.

Again, too low of a testing population to be conclusive, but at least it says something about the safety of minoxidil for beard growth.

At first glance, it sure seems like it, although more evidence needs to be gathered in order to be conclusive.

From personal experience, I’ve had minimal side effects like some slight dried out skin when using the liquid minoxidil that subsided when I switched to minoxidil foam. What I can say is that it certainly worked.

Is Rogaine safe for beard

Rogaine is a brand of minoxidil foam and liquid. Just like every minoxidil brand, it is not FDA approved for use on the face in order to grow a beard, but it is FDA approved for use on the scalp. However, just because it is not FDA approved does not mean it is necessarily unsafe. 

There is simply not enough conclusive evidence to deem Rogaine safe for beard growth. But as shown in the previous studies, anecdotes and my own personal experience with the product, it is certainly looking like it’s safe to use for beard growth.

Keep in mind that minoxidil foam and liquid like Rogaine and Kirkland and all other minoxidil brands are FDA approved and are deemed safe to use for male and female pattern baldness.
