Step 01Step 1: Finasteride Blocks DHT Production
Finasteride works by inhibiting the enzyme 5-alpha reductase, which converts testosterone into dihydrotestosterone (DHT). DHT is the primary hormone responsible for shrinking hair follicles in androgenetic alopecia. By reducing DHT levels in the scalp by up to 60%, finasteride helps prevent further miniaturization of hair follicles and allows them to return to their normal size.
