Finasteride: Why Men Are Using It, What It Does, And 5 Ways To Prevent (2023)

Hair loss is one of the most frustrating and devastating side effects of aging. It can lead to a lack of confidence and self-esteem, and even social isolation. Finasteride has been shown in clinical studies to slow hair loss in both men and women who have hereditary hair loss. And while it’s only an option for those with a family history of hair loss, there are many things you can do to keep your hair from thinning or disappearing completely.


Finasteride is a medication that is used to treat enlarged prostate and male pattern baldness. It can be taken by mouth or applied topically to the skin. Finasteride is in a class of medications called 5-alpha-reductase inhibitors.

5-alpha-reductase is an enzyme that converts testosterone to dihydrotestosterone (DHT). DHT is a hormone that plays a role in the development of benign prostatic hyperplasia (BPH) and male pattern baldness.

Finasteride inhibits the production of DHT, which leads to decreased levels of DHT in the body. This leads to shrinkage of the enlarged prostate and slowed hair loss.

The FDA has approved finasteride for use in men with BPH and male pattern baldness. It is not approved for use in women or children.

There are two forms of finasteride: oral and topical. Oral finasteride is available as a generic drug and as the brand-name drugs Proscar and Propecia. Topical finasteride is available as the brand-name drug Propecia.

What is Finasteride?

Finasteride is a medication that is used to treat male pattern baldness. It is a prescription drug that is taken orally. Finasteride works by inhibiting the production of DHT, which is a hormone that plays a role in hair loss. Finasteride has been shown to be effective in treating male pattern baldness and can help to prevent further hair loss. There are a few side effects associated with finasteride, but they are rare and usually resolve with continued use of the medication.

How does it work (includes side effects)?

Finasteride (Propecia) is a prescription medication taken by mouth for the treatment of male pattern baldness in men only. The FDA-approved drug finasteride can be taken by men aged 18 and over. It’s not for women or children.

Finasteride works by decreasing the amount of the hormone dihydrotestosterone (DHT) in your body. DHT is a male sex hormone that’s linked to balding. Less DHT means slowed hair loss and increased hair growth on your head. It typically takes three to six months before you see results from finasteride. New hair growth may be softer and thinner than your existing hair. You may need to take finasteride for at least four months before you see results.

Side effects of finasteride include:

-Erectile dysfunction
-Decreased libido
-Trouble ejaculating
-Enlarged breasts

In rare cases, allergic reactions including rash, itching, hives, and swelling of the lips, tongue, throat, or face may occur. If these effects persist or worsen, notify your doctor promptly.
