Finasteride works by reducing levels of the hormone DHT (dihydrotestosterone), which is known to shrink hair follicles and cause hair loss. By blocking DHT, Finasteride helps slow or prevent hair loss. Minoxidil, a topical solution or foam, stimulates hair follicles by increasing blood flow to the scalp, promoting hair regrowth over time. When used together, these two treatments complement each other to target both hair loss prevention and new growth.
