What is finasteride and how do I take it?
Finasteride is a 5α-reductase inhibitor that reduces the formation of the androgen dihydrotestosterone (DHT) in certain body tissues, including the scalp. DHT contributes to hair loss in men with androgenetic alopecia (male pattern baldness). Finasteride is typically prescribed in a 1mg dose, taken once daily. It is the only oral medication approved by the FDA for male pattern baldness, and it has been used by millions of men around the world since its first approval in the 90s under the brand name Propecia. Finasteride requires a doctor’s prescription (quickly processed with Shapiro MD).
What is Propecia?
Propecia was the brand name for finasteride 1mg when it was first FDA approved and launched by Merck Research Labs. Finasteride lost patent protection about 10 years ago, which has made this medication available as a generic at much lower prices. Finasteride is also approved under the brand name Proscar, and at a higher dose, for the treatment of an enlarged prostate.
What should I expect?
Progress is often visible within 6 months, however, use for at least 12 months is recommended by most doctors to monitor efficacy through multiple hair growth cycles.
