Q

What is the mechanism of action for finasteride in treating male pattern baldness?

A

Finasteride, known as Propecia, works by inhibiting the enzyme 5-alpha reductase type II, which decreases DHT concentration in the scalp by 60-70%. This reduction helps prevent further hair loss in about 60-70% of men, with some experiencing hair regrowth.
