How Finasteride works

Finasteride is a medication that can help prevent hair loss in men.

It is an FDA-approved medicine for hair loss.

It works by blocking the production of the Dihydrotestosterone (DHT) hormone.

This hormone is responsible for causing Male Pattern Baldness or Androgenetic Alopecia.

DHT is produced in the body as a byproduct of Testosterone.

It plays a vital role in developing sexual organs and body hair during puberty.

Yet, in adult men, DHT can attach to receptors in the scalp and cause hair follicles to shrink.

It further disrupts the growth of the hair cycle and leads to hair loss, and often results in a receding hairline or around the crown.

Finasteride tablets reduce the levels of DHT in the body.

This further protects hair follicles from damage and can even help to regrow hair in some cases.

It can also help to prevent further hair loss from occurring.

Finasteride treatment is valuable for men who are experiencing Male Pattern Baldness.
