About the Procedure

Last Updated: 02.25.2021

Finasteride is a type II 5a-reductase inhibitor that decreases serum and scalp levels of dihydrotestosterone (DHT). DHT is an androgen that creates miniaturization of follicles, weakening of hair structures, and overall unhealthy hair. By decreasing DHT production, hair loss is reduced. Since finasteride reduces the production of androgens, which are male sex hormones, side effects from taking the medication may include decreased libido and sexual stamina. Alternative medications for hair loss include dutasteride and tofacitinib. Typically, 1 dose is taken per day orally of finasteride to help hair loss. Results can take anywhere between 3-6 months to show. Continued use of the drug is necessary to maintain results.

The goal of finasteride is to reverse the early stages of hair loss created by thinning hair, bald spots and receding hairlines.
