oral minoxidil tablets can increase beard growth in some people, because a common effect is extra hair growth on the face and body. However, evidence specifically for beard enhancement is limited. The better direct study evidence is for topical minoxidil applied to the beard area, not tablets.

Oral minoxidil for hair is off-label and works systemically, so it may also cause unwanted body hair. Possible adverse effects include:

It should not be self-started, especially if you have heart disease, low blood pressure, kidney disease, take blood-pressure medication, or have a history of fluid around the heart. A dermatologist can decide whether it is appropriate and monitor blood pressure and side effects.

If your only goal is beard growth, topical minoxidil is usually the more conservative option, though it is also off-label for the beard and can cause irritation or unwanted hair where it spreads. Results are variable and commonly take several months; gains may diminish after stopping.

A 2025 systematic review of oral minoxidil supports its hair-growth effect in alopecia generally, but does not establish tablets as a proven beard-specific treatment. A small randomized study cited in this beard-minoxidil summary found improved beard density with topical 3% minoxidil over 16 weeks.

For beard growth, minoxidil tablets may help because they can stimulate facial and body hair, but they are not the first choice solely for a beard.

So: yes, tablets can promote beard growth, but topical minoxidil is generally the more reasonable option to discuss first with a dermatologist.
