Key Concepts

Finasteride

Finasteride is a medication that functions as a 5-alpha reductase inhibitor. It decreases the conversion of testosterone to dihydrotestosterone (DHT), which is instrumental in conditions related to hormone-dependent tissue growth. Its application varies with dosage, being prescribed at lower doses for hair loss and higher doses for benign prostatic hyperplasia.

5-Alpha Reductase Inhibition

This concept refers to the mechanism by which finasteride slows or prevents the conversion of testosterone to dihydrotestosterone (DHT). By reducing DHT levels, the drug is effective in treating conditions where DHT plays a detrimental role, such as male pattern hair loss and, at different dosing, benign prostatic hypertrophy.

Androgenetic Alopecia (Male Pattern Hair Loss)

This term describes the common form of hair loss in males, characterized by a receding hairline and thinning of hair on the crown. Finasteride, at a dose of 1 mg daily, is specifically approved for this condition by reducing DHT levels that contribute to the miniaturization of hair follicles.
