Hair loss is a common and frustrating condition to deal with, and more than some other conditions, hair loss can carry the extra weight of social pressure and embarrassment.

Medicated products can help stop hair loss and regrow hair for many users. Two of the most popular types of medication are finasteride (Propecia®) and minoxidil (Rogaine®, LONITEN®). So how do finasteride and minoxidil compare for your hair loss needs?

Learn about finasteride and minoxidil to find the best hair loss treatment for you.

What is finasteride?

Finasteride1 is an oral medication used to treat hair loss in men. It works by blocking the enzyme 5-alpha-reductase. This enzyme converts testosterone into a hormone that can cause hair loss.

Finasteride users can experience an increase in hair follicles on the scalp to minimize the appearance of hair loss or baldness.

Common brands of finasteride include Proscar and Propecia. However, the medication is widely available in generic forms and is prescribed in 1 mg doses from RedBox Rx.

What is minoxidil?

Minoxidil2 is a medication used to prevent hair loss. It is commonly used for male pattern baldness but has also been found effective for women who experience hair loss. Minoxidil is available both as a topical application and as an oral medication. The most common brand name of topical minoxidil is Rogaine, most often prescribed in 2% and 5% strength topical applications. RedBox Rx offers 5% minoxidil foam. Another brand name of minoxidil, LONITEN, is available as an oral tablet prescription.

With continued use, minoxidil has been proven to help stimulate hair growth in users. It works by shortening the resting phase of hair follicle growth and encouraging follicles to move into a lengthened growing, or anagen, phase.3

What’s the difference between finasteride and minoxidil?

The main differences between finasteride and minoxidil are the use and the function. Finasteride helps regrow hair follicles, and minoxidil helps prevent hair loss.

Minoxidil is available over the counter as a topical medication. While oral minoxidil and finasteride are available by prescription only.

Because of the complementary functions of finasteride and minoxidil, both medications can be used in tandem to slow down and reverse hair loss in men. Finasteride is not recommended for use in women with any pregnancy potential due to harm to a developing infant.

Can finasteride and minoxidil be used together?

Finasteride and minoxidil can be used together to combat hair loss in men. These two medications work synergistically to prevent hair loss and regrow hair follicles.

Finasteride is an oral medication that helps spark the regrowth of hair follicles on the scalp. Minoxidil, in both oral and topical forms, helps to slow or stop hair loss at the source. The different applications and functions of the medications make them complementary.

  • Cold sweats.

  • Confusion.

  • Dizziness or lightheadedness.

What results can you expect from finasteride and minoxidil?

If both medications work as intended, you can expect to see a decline in hair loss and an increase in hair regrowth. Results for individuals will vary; however, in one study,10 94.1% of men using a combination of finasteride and minoxidil showed improvement in hair growth compared to 80.5% of men who only used finasteride and 59% of men who only used minoxidil.

Both finasteride and minoxidil must be used daily for the best results. If either medication is stopped, the hair loss could continue and hair regrowth will stop. Therefore, finasteride and minoxidil must be continued indefinitely if hair loss treatment is desired.
