How does finasteride and dutasteride help with hair loss?
Dr. Anna Chacon, board-certified dermatologist, says that finasteride and dutasteride are DHT blockers, which means they block the conversion of testosterone into DHT which causes hair follicles to miniaturize, leading to hair loss. By reducing DHT levels in the body, finasteride and dutasteride help to slow or even reverse the process of follicular miniaturization6 7 .

Similarities between finasteride and dutasteride
According to Dr. Chacon the main similarity between finasteride and dutasteride is that they are both prescription medications used to treat male androgenetic alopecia and they work similarly by reducing the levels of DHT in the body which regulates abnormal prostate growth, reduces hair loss, and stimulates hair growth8 9 .
Both products have similar prices and are covered by most commercial insurance health plans, besides they can both be used in combination with topical minoxidil to maximize hair growth.
Finasteride vs dutasteride: what are the differences?
The main difference between these two drugs according to Dr. Chacon is that while they work in similar ways, dutasteride is slightly more potent since it blocks more of the conversion of testosterone to dihydrotestosterone (DHT)10.
Another important difference is that for some reason, only finasteride is FDA- approved for the treatment of androgenetic alopecia while dutasteride is used as an off-label treatment.
