You may have never heard of DHT until recently, but if you’re experiencing hair loss, it’s probably at the root (sorry) of your problems.

Long story short: DHT, or dihydrotestosterone, is a male sex hormone that binds to receptors in your scalp and precipitates male pattern baldness in genetically-susceptible men.

What exactly is DHT?

DHT is an androgen [male sex hormone] which is made from testosterone in the prostate, testes, and certain other tissues. It’s needed to develop and maintain male sex characteristics, such as a deep voice, facial hair, and muscles.

Testosterone converts to DHT with the help of 5α-reductase, an enzyme that is held in the oil glands of a hair follicle. If you’re genetically prone to male pattern baldness, DHT binds to receptors in your hair follicles, causing the follicle to miniaturize (which basically means shrink) and, eventually, to stop producing hair altogether.

The good news?

This doesn’t happen overnight. Hair follicles that are sensitive to DHT must be exposed to the hormone for an extended period before the miniaturization process is complete and the follicle stops producing hair. Even when DHT is suppressed, hair follicles continue to thrive — so the earlier you take action, the more hair you’ll keep. That’s where DHT blockers come in.


Can you tell me more DHT blockers?

We can! While you can go down an internet rabbit hole and read about all kinds of “DHT blockers” (shampoos, pumpkin seed oil, emu oil—yeah, that one made us pause, too), there’s only one that’s proven to work. And that one is finesteride.

Finasteride (generic Propecia®) is a prescription tablet that effectively blocks DHT and stops further hair loss, including receding hairlines. It works by binding to the 5α-Reductase enzyme, effectively inhibiting your body from producing DHT in the first place.


OK—but do DHT blockers really work?

Yes! A study by the American Academy of Dermatology found that finasteride is effective.

Not only does it halt hair loss, but it can even spur future growth. As Dr. Jane Kardashian told GQ, “In studies, 80% of men taking finasteride 1mg preserved their original hair follicle counts and 64% experienced some regrowth after two years of continued use.”

Those are pretty great numbers.


Quick recap

DHT is the primary hormone responsible for male pattern baldness, so the surest way to prevent hair loss and mitigate the impact of male pattern baldness is to block DHT.

So, are you ready to halt your hair loss?

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.
