Understanding Male Pattern Baldness
Androgenetic Alopecia (male pattern baldness) is driven primarily by Dihydrotestosterone (DHT)—a potent hormone converted from testosterone. DHT binds to susceptible hair follicles, causing them to shrink (miniaturize) and produce thinner, shorter hair over time.
How Finasteride Halts Hair Loss
Finasteride is a clinical 5-alpha reductase (5AR) inhibitor:
- Blocks DHT Conversion: By blocking the 5AR enzyme, Finasteride prevents the conversion of testosterone into DHT, lowering systemic DHT levels by up to 70%.
- Follicle Revival: Halting DHT exposure stops miniaturization, allowing follicles to return to the active growth (anagen) phase.
