Executive General a gist of the main points and Summary
Finasteride is an oral medication commonly sold under brand names such as Propecia for treatment of male pattern hair loss. It acts by inhibiting the enzyme 5-alpha-reductase, which converts testosterone into dihydrotestosterone (DHT). Lowering DHT around hair follicles may reduce progressive hair thinning and in some men produce partial regrowth.
Summary of the key points at a glance:
- Pharmacologically active constituent: finasteride
- Primary indication for hair: androgenetic alopecia in adult men, typically 18 years and older
- Common tablet strengths: 1 mg for hair loss; 5 mg tablets are marketed for benign prostatic hyperplasia

Sanctioned Applications
In the United States, 1 mg finasteride tablets are approved for treating male pattern hair loss in adult men. Ongoing daily use is required to continue the benefit; stopping treatment usually leads to gradual reversal of any gains within months.
The 5 mg formulation is approved for benign prostatic hyperplasia (BPH). While 5-alpha-reductase inhibitors have been evaluated in other prostate conditions, they are not a standard treatment for prostate cancer by themselves. Discuss prostate-related choices under the care of your clinician.
