Finasteride is a medication primarily used to treat hair loss (androgenetic alopecia) in men. It works by reducing the levels of dihydrotestosterone (DHT) in the scalp, which is the hormone responsible for hair loss. This medication is available in oral tablet form and is only suitable for adult men.

Finasteride is classified as a type II 5-alpha reductase inhibitor, which means it inhibits the conversion of testosterone into DHT. By reducing DHT levels, finasteride helps to promote hair growth, prevent further hair loss, and improve hair thickness and density.

How Does It Work?

Finasteride works by blocking the enzyme 5-alpha reductase, which is responsible for converting testosterone into DHT. By inhibiting this enzyme, finasteride reduces the levels of DHT in the scalp, which in turn helps to promote hair growth and prevent further hair loss.

Who Can Benefit from Finasteride?

Finasteride is primarily used to treat male pattern hair loss, also known as androgenetic alopecia. It is suitable for adult men who are experiencing thinning hair or a receding hairline. It is not recommended for use in women or children.

Finasteride can also be used to treat benign prostatic hyperplasia (BPH), a condition in which the prostate gland becomes enlarged. By reducing the levels of DHT, finasteride can relieve symptoms such as frequent urination, difficulty starting or maintaining urination, and weak urine flow.


When it comes to the application of finasteride, there are several benefits to consider:

  1. Treatment of male pattern baldness: Finasteride is primarily used to treat male pattern baldness, also known as androgenetic alopecia.

While some individuals may experience mild side effects such as decreased sexual desire or difficulty in achieving an erection, these effects are often temporary and resolve after discontinuing the medication.
