Finasteride addresses hair loss in men by inhibiting the production of dihydrotestosterone (DHT), an androgen hormone derived from testosterone. DHT is believed to shrink hair follicles, leading to hair loss in many men.

Frequently asked questions
Finasteride, in a 1 mg dose, treats male pattern baldness. Research shows it prevented further hair loss in 83% of men over two years, with 66% experiencing some hair regrowth.
The short answer is yes. A study summarizing the findings of three trials on finasteride showed that some men experienced hair regrowth. The authors noted, “Based on standardized clinical photography, the chances of mild to moderate visible regrowth are 61% on the vertex (with an additional 5% achieving great visible regrowth) after 2 years and 37% on the frontal area after 1 year.” In two studies on hair loss at the crown of the head, 72% of men saw further hair loss prevention after 2 years. For clarity, the vertex refers to the crown of the head, and the frontal area refers to the frontal or receding hairline.
If you are taking finasteride for hair loss, it may take 3-6 months before you notice results, with optimal outcomes typically seen after 12 months. Finasteride begins working immediately by blocking the conversion of testosterone and lowering DHT levels as soon as it is absorbed by your body. However, hair grows in phases, so visible changes may take several months, even with consistent use. Rest assured, finasteride is working. Over time, it accumulates in your body, and a modest daily dose (typically 1 mg) significantly reduces DHT production, helping to protect your hair.
