Kết luận

Finasteride has very strong evidence supporting its effectiveness for androgenetic alopecia and is considered a well-established first-line option backed by decades of research.

  • 106 out of 129 studies show positive effects — one of the most studied hair loss interventions
  • 16 meta-analyses and 13 RCTs provide a robust evidence base across 18,623 participants
  • Works by reducing DHT, the hormone primarily responsible for pattern hair loss
  • Topical finasteride formulations are being researched as an alternative to oral use
