As with any medication or hair growth therapy, it's essential to know the facts before using them. Consider this your guide to Finasteride and how it may be able to help you with hair loss.

What is Finasteride?

Finasteride (brand name Propecia) is an oral tablet used to treat male-pattern baldness and enlarged prostate issues. This medication comes in both a generic and brand name form.

Do You Need a Prescription for Finasteride?

Using Finasteride for Hair Loss

Finasteride was initially developed to treat an enlarged prostate but was eventually found to block the effects of dihydrotestosterone (DHT), a hormone known to cause hair loss. Clinical studies have found that Finasteride can significantly increase the hair count and slow the progression of balding.

Is Finasteride Effective for Hair Loss?

Yes, finasteride has been found to increase hair growth and decrease hair loss progression in men.

How Does Finasteride Work?

Finasteride treats androgenetic alopecia by obstructing the male hormone, DHT. If you didn't know, When your body has too much testosterone it converts it into dihydrotestosterone or DHT. DHT is a hormone that causes hair loss by attacking your hair follicles. Finasteride will directly block the DHT hormone, resulting in hair regrowth and halting hair loss.

Finasteride for Men

Finasteride can treat prostate hyperplasia and male pattern baldness in men. Finasteride has been found to increase hair growth on the scalp without impacting body hair growth.

Finasteride for Women

Finasteride can be used by women but it is not a common treatment for female pattern baldness. Most studies have been developed around male pattern hair loss, so some caution should be used. Finasteride is also teratogenic, meaning if taken while pregnant, it can cause congenital disabilities. If you plan to become pregnant, finasteride is not a safe option for hair growth.

Dosage for Women
