Key takeaways
4 points- In a meta-analysis of 5 randomized trials, finasteride plus topical minoxidil beat either drug alone on photographic scores and on the share of men with marked improvement1.
- Side effects did not differ significantly between the combination and either drug alone1.
- Finasteride is for men only and is contraindicated in pregnancy2.
- Combination pills with oral minoxidil are compounded and off-label; the tablets are approved only for severe high blood pressure7.
Why combine them
Finasteride lowers DHT, the hormone that shrinks follicles in pattern hair loss2. Topical minoxidil is sold over the counter to regrow hair on the top of the scalp3. In a 2022 network meta-analysis in men, each led at a different time point: 5 mg oral minoxidil at 24 weeks and 1 mg finasteride at 48 weeks4.
What the combination trials show
A 2020 meta-analysis pooled 5 randomized trials. All compared the combination with minoxidil alone, and 2 also compared it with finasteride alone1. The combination gave higher global photographic scores, more patients with marked improvement and fewer with no change or worsening; hair density change and adverse events did not differ significantly1. The authors said the best concentrations still need better-designed trials1.
Combination pills and compounded mixes
Online clinics sell compounded products that combine finasteride with oral or topical minoxidil. Compounded drugs are not FDA-approved, and the FDA has warned about compounded topical finasteride6. Using minoxidil tablets for hair growth is not an approved indication7; at hair-loss doses in 1,404 people, unwanted hair growth affected 15.1% and lightheadedness 1.7%5.
