Finasteride is a medication that is commonly used to treat hair loss and enlarged prostate in men. It belongs to a class of drugs called 5-alpha-reductase inhibitors, which work by blocking the conversion of testosterone into dihydrotestosterone (DHT) – a hormone that can cause hair follicles to shrink and eventually stop producing new hair.

By inhibiting the production of DHT, finasteride helps to prevent further hair loss and may even promote hair regrowth in some individuals. This makes it a popular treatment option for male pattern baldness, also known as androgenetic alopecia.

In addition to its use in treating hair loss, finasteride is also approved by the FDA for the treatment of benign prostatic hyperplasia (BPH), a condition in which the prostate gland becomes enlarged, causing symptoms such as urinary frequency, urgency, and difficulty passing urine.

It is important to note that finasteride is not without potential side effects, including decreased libido, erectile dysfunction, and breast tenderness. It is always recommended to consult with a healthcare provider before starting any new medication, including finasteride.
