Minoxidil for Beard Growth: What Studies Report

Disclosure: PrescribedRX sells its own treatments, so we compete with some of the companies covered here, and we may earn affiliate commissions.

Short answer: Minoxidil is labeled as a scalp hair loss treatment, not for beards. The Men’s Rogaine 5% foam Drug Facts label says it is “to regrow hair on the top of the scalp” and says “do not apply on other parts of the body,” so using it on the face is off-label (Rogaine foam label). The main controlled study in men not taking testosterone was a 16-week, placebo-controlled trial of 3% minoxidil lotion, applied to the beard area twice daily by 48 healthy Thai men (Ingprasert 2016; ClinicalTrials.gov).

Below, each finding is tied to the label or study that reported it, along with the size and population of each study, so you can see how much evidence there actually is.

Is minoxidil approved for beard growth?

No. Over-the-counter minoxidil is labeled for scalp hair loss. The Men’s Rogaine 5% foam Drug Facts on DailyMed (updated November 2024) say (Rogaine foam Drug Facts):

• Uses: “to regrow hair on the top of the scalp (vertex only…)”
• When using this product: “do not apply on other parts of the body”
• Directions: “apply half a capful 2 times a day to the scalp in the hair loss area”
• Stop use and ask a doctor if “unwanted facial hair growth occurs”

The label lists unwanted facial hair growth as a reason to stop, not as a use. A 2024 case report in SAGE Open Medical Case Reports titled its paper “Facial hair enhancement with minoxidil: an off-label use,” and its authors noted that most reports of beard use come from “informal reports on online communities” rather than the medical literature (Shokravi 2024).

Does minoxidil work for beards? What the 2016 trial reported

The main placebo-controlled beard trial in men not taking testosterone is Ingprasert and colleagues, published as a short letter in the Journal of Dermatology in 2016 (PubMed 26893270). It was run at Mae Fah Luang University Hospital in Bangkok between November 2014 and March 2015 and registered as NCT02275832 (ClinicalTrials.gov).

• Who: 48 healthy men enrolled; 46 of 48 completed the study (registry; Almurayshid 2020 review).
• What: 0.5 mL of 3% minoxidil lotion or placebo, applied to the beard area twice daily for 16 weeks (review).
• Main outcome: change in a global photographic assessment at 16 weeks; hair count was a secondary outcome and hair diameter another measure (registry).
• Reported results: the trial was published as a short research letter without an abstract, and its full text is not publicly available. A published review reports no significant change in hair diameter and no significant side effects (review).

No follow-up after stopping was reported in the sources above, and a 2024 study team wrote that further studies are needed to see whether gains last after discontinuing (Marinelli 2024).

What do other facial-hair studies report?

The two other studies cited here were done in transgender men taking testosterone, a different population from the 2016 trial, so their results cannot be assumed to apply to other men. The third report is a single case.

• Wattanawinitchai 2026: a randomized, double-blind, placebo-controlled trial in 69 transgender men on stable gender-affirming hormone therapy. Participants applied 3% minoxidil or a vehicle twice daily for 12 weeks. The authors reported beard density changes of 11.16 vs 0.08 hairs/cm2 (p = 0.01), beard diameter changes of 5.37 vs -0.33 micrometers (p = 0.01), and mustache density changes of 18.45 vs 1.74 hairs/cm2 (p = 0.003). They wrote that adverse events were minimal and comparable between groups (PubMed 41778417).
• Marinelli 2024: 16 people assigned female at birth on testosterone with incomplete beard growth, with no placebo group. After 6 months of topical minoxidil, median chin scores on a modified Ferriman-Gallwey scale went from 1 to 4 (p of 0.002 or less) (PubMed 38644453).
• Shokravi 2024: a case report of identical twin men, one of whom used topical 5% minoxidil on his beard and mustache for over a year while the other did not (PubMed 38404498).

What do minoxidil beard before and after results look like?

We do not show before and after photos. In the studies above, “before and after” meant a measured change over 12 to 16 weeks, or 6 months in the uncontrolled study: physician-rated photographs and hair counts in the 2016 trial (registry), and dermoscopy-measured density and diameter in the 2026 trial (Wattanawinitchai 2026). None of these studies reported what happened after people stopped.

For scalp use, the Rogaine label says “continued use is necessary” to keep regrowth (Rogaine foam label). For scalp timelines by week, see our guide to minoxidil results at each trial timepoint.

What about oral minoxidil and facial hair?

Minoxidil tablets are a prescription blood pressure drug. The minoxidil tablets prescribing information says they are indicated only for hypertension that is “symptomatic or associated with target organ damage” and not manageable with maximum doses of a diuretic plus two other drugs, and it carries a boxed warning that minoxidil “may produce serious adverse effects” (minoxidil tablets prescribing information).

The same prescribing information describes hair growth as a side effect (minoxidil tablets prescribing information):

• “Elongation, thickening, and enhanced pigmentation of fine body hair are seen in about 80% of patients” taking the tablets.
• It “develops within 3 to 6 weeks after starting therapy.”
• It is “usually first noticed on the temples, between the eyebrows, between the hairline and the eyebrows,” and later on the back, arms, legs and scalp.
• After stopping, “new hair growth stops,” and “1 to 6 months may be required for restoration to pretreatment appearance.”

Using tablets for hair loss is off-label. Our oral minoxidil guide covers what studies report, and the oral minoxidil side effects page covers reported side effects in more detail.

What side effects and warnings does the Rogaine Drug Facts label list?

The Rogaine foam Drug Facts list these warnings, among others (Rogaine foam label):

• “For external use only.” The foam is “Extremely Flammable”; avoid fire, flame or smoking during and right after use.
• Avoid contact with the eyes.
• Ask a doctor before use if you have heart disease.
• “Some people have experienced changes in hair color and/or texture.”

In the 2026 trial, the authors described adverse events as minimal and similar between groups (Wattanawinitchai 2026). In the 2024 study, one person stopped after about a week because of flushing and skin irritation, according to the full text of that study (Marinelli 2024).

When should you talk to a doctor?

The Rogaine foam label says to stop use and ask a doctor if any of these happen (Rogaine foam label):

• chest pain, rapid heartbeat, faintness, or dizziness
• sudden, unexplained weight gain
• your hands or feet swell
• scalp irritation or redness
• unwanted facial hair growth

The same Drug Facts label says to ask a doctor before use if you have heart disease. For any other question about minoxidil, talk to a licensed provider. General safety information is on our hair loss safety information page.
