Finasteride is an effective, FDA-approved medication that reduces DHT and treats male pattern baldness.
If you’ve noticed your hairline receding or the hair on your scalp thinning, you may have thought about using finasteride to stop your hair loss and retain the hair you still have.
Currently, finasteride is only available in the United States with a prescription. However, getting a prescription for finasteride is a relatively simple process if you already have visible symptoms of hair loss.
Below, we’ve explained how finasteride works and how you can purchase it. We’ve also looked at other treatments for hair loss that are available over the counter, many of which can be used alongside finasteride for better results.
More specifically, finasteride treats male pattern baldness by inhibiting the effects of the 5-alpha reductase enzyme, which is responsible for converting testosterone into DHT.
In people genetically predisposed to hair loss, DHT can damage the hair follicles and stop them from growing new hairs. Over time, this can cause everything from a mild M-shaped hairline to significant levels of hair loss that affect almost all of your scalp.
Our guide to DHT and hair loss goes into more detail on how DHT can affect your hair follicles and contribute to male pattern baldness.
By lowering DHT levels throughout your body, finasteride may reduce or prevent damage to your hair follicles. This helps to slow down, prevent or reverse any hair loss caused by male pattern baldness.
No. Currently, finasteride is not available over the counter in the United States. In order to buy and use finasteride, you’ll need to have a valid prescription from your healthcare provider.
Rules and regulations regarding medications can vary from country to country. If you’re located outside the United States, you can check your country’s medication regulations to find out what restrictions apply to finasteride in your area.
Since finasteride requires a prescription, you’ll need to see a healthcare provider before you can legally purchase and use it. Luckily, this process isn’t complicated or expensive.

Finasteride is an easy medication to use. To prevent hair loss, all you’ll need to do is take one tablet per day, ideally at approximately the same time every day.
Finasteride starts reducing DHT levels as soon as it’s absorbed by your body. However, it may take three months or longer before you notice any changes in your hair count, hair thickness or other aspects of your hair health.
After one year, you should see an improvement from finasteride. If you can’t see any change in your hair after one year, it’s best to talk to your healthcare provider.

It’s important to keep using finasteride even if you don’t notice any improvements during the first few months. If you stop using finasteride, your DHT levels will return to normal and any hair loss you previously experienced may continue.
Although finasteride requires a prescription, several treatments for hair loss are available over the counter. Many of these are supported by scientific evidence and can be used at the same time as finasteride for improved results.
Over-the-counter treatments for hair loss include:
