Minoxidil for Eyebrows: Does It Work, and Is It Safe?
Short answer: topical minoxidil is approved for scalp hair loss, not eyebrows, so using it there is off-label. Small trials using 2% lotion or gel found it can improve eyebrow hair, but those trials used a lower strength than our 5% scalp serum, and there is no standard eyebrow dose. If you want fuller brows, talk to a dermatologist before trying it.
Is minoxidil approved for eyebrows?
No. In the US, topical minoxidil, sold over the counter in 2% and 5% strengths, is approved for hair regrowth on the scalp. Using it on eyebrows is considered off-label, which means it has not been formally approved or tested by regulators for that area.
What the studies found
| Trial | What they found |
|---|---|
| Randomized, double-blind, placebo-controlled split-face trial, 40 patients: 2% minoxidil lotion on one eyebrow, placebo on the other | The authors concluded 2% lotion was a safe and effective treatment for thin eyebrows. A clinic summary of this trial reports improvements in thickness, fullness, and hair count within about four months, with mild side effects. |
| Randomized trial, three groups of 20: once-daily 2% minoxidil gel vs 0.01% or 0.03% bimatoprost gel | Bimatoprost was found to be about as effective as minoxidil, with a better response at the 0.03% strength. |
Together, the evidence suggests minoxidil may help some people regrow eyebrow hair, but the trials were small.
Why you should not just use your scalp serum
- The strength is different. The trials above used 2%. Our Soti serum is 5% and is made and directed for the scalp.
- There is no standard eyebrow dose. Without an established schedule, people are guessing how much to use and how often.
- It is close to your eyes. Keep minoxidil away from the eyes, because getting it in them can cause irritation.
- Side effects are possible. The most frequently reported side effects of topical minoxidil are allergic or contact dermatitis. Palpitations and a rapid heartbeat have also been reported, so check with a doctor first if you have a heart condition.
- The evidence is limited. Small trials cannot tell you how well it works for you.
What we would suggest
If thin eyebrows bother you, a dermatologist can look for the cause and talk you through options, including prescription products such as bimatoprost, which was compared with minoxidil in the trial above. We make our Soti 5% serum for the scalp, and we do not recommend using it on eyebrows. For scalp hair loss, see our guides to how long minoxidil takes to work and its side effects. We cover the same off-label question for facial hair in our beard article.
Quick answers
Can I use my 5% scalp minoxidil on my eyebrows?
We do not recommend it. The eyebrow trials used 2% or lower, and no standard dose exists.
How long did results take in the studies?
The trial summaries describe improvements over roughly four months.
Is minoxidil on eyebrows approved?
No. It is approved for scalp use only, so eyebrow use is off-label.
