Losing hair? You’re not alone: two out of three guys will experience some form of male pattern baldness by the time they’re 35. That’s where finasteride and minoxidil come in, but what are they?
Finasteride and minoxidil are the two most prominent—and clinically proven—treatments for men’s hair loss. Although they both work to achieve the same goal (slowing down hair loss and promoting regrowth), they work in totally different ways. Let’s break it down:
Finasteride is a DHT blocker. DHT (dihydrotestosterone) plays a starring role in male pattern baldness; it’s a hormone that binds to men’s hair follicles and damages them, ultimately rendering them unable to grow new hair. Finasteride prevents hair loss by stopping your body from converting testosterone into DHT.
Minoxidil is a vasodilator. When applied to your scalp, it widens the blood vessels, facilitating the flow of blood to hair follicles. This increased blood flow, in turn, delivers more oxygen and nutrients to hair follicles, possibly promoting hair growth.
Finasteride helps stop hair loss and grows new hair by blocking DHT.
Minoxidil doesn’t stop hair loss, but it does help grow new hair thicker and faster than before.
Finasteride and minoxidil (the only two FDA-approved products to treat men’s hair loss) have been proven successful at treating hair loss in men, according to multiple studies.
A five-year study on the efficacy of finasteride in 801 Japanese men with androgenetic alopecia showed improvement in 99.4% of participants. A 16-week randomized study of male subjects with androgenetic alopecia showed that minoxidil was statistically significantly superior to the placebo in increasing hair count.
Finasteride is a pill, which you take orally once a day.
Minoxidil is a topical solution, which you apply to your scalp twice a day.
Yes! Finasteride and minoxidil work through different mechanisms, so there is no risk in using both products at the same time. In fact, taking them in tandem may even be the most effective means of tackling hair loss: A 2015 randomized and comparative study of the combined treatment of male androgenetic alopecia with oral finasteride and topical minoxidil found that “the combined medication showed the best efficacy.”
Finasteride and minoxidil are different medications, and each serves a different purpose. Because finasteride stops hair loss at its source by blocking DHT production, many doctors will recommend it as the first step to combat male pattern baldness.
Ultimately, combatting hair loss is a commitment—in order for the treatments to work, you need to use finasteride and minoxidil daily. Increase your chances of success by picking the right solution for your needs and lifestyle.

Finasteride is an oral medication used to treat male pattern baldness in men only. It is not for use by women. When used by men, finasteride is generally safe but it can also cause serious side effects, including but not limited to allergic reactions, sexual dysfunction, and high-grade prostate cancer. Most patients find that problems with sexual function resolve when they stop taking the medicine. For full prescribing information, view the drug label information.
