Finasteride is a medication used to treat hair loss in men (male androgenetic alopecia) Alopecia) and is used to treat benign prostatic hyperplasia (BPH), a benign enlargement of the prostate gland. It works by inhibiting the conversion of testosterone in Dihydrotestosterone (DHT) inhibits, a hormone that plays a central role in both the development of BPH and hair loss.
Finasteride is a 5-alpha reductase inhibitor that specifically inhibits the enzyme 5-alpha reductase type 2. This enzyme is responsible for converting testosterone to DHT in the body. By reducing DHT levels, finasteride can slow the progression of hair thinning and even promote hair regrowth on the scalp in men with androgenetic alopecia. In the treatment of benign prostatic hyperplasia (BPH), reducing DHT can help shrink the prostate gland and alleviate symptoms such as difficulty urinating.
For the treatment of hair loss, finasteride is typically taken orally at a dose of 1 mg daily. When treating benign prostatic hyperplasia (BPH), it is administered at higher doses (for example, 5 mg daily). The effects on hair loss often only become apparent after several months of regular use, and continued application is necessary to maintain the benefits.
Although finasteride is well tolerated by many men, it can have side effects, including:
These side effects are reversible in most men after stopping the medication, but may persist in some even after treatment has ended.
Finasteride is an effective treatment option for men suffering from hair loss or symptoms of benign prostatic hyperplasia. A thorough discussion with a doctor can help in making an informed decision about using this medication.
