    GlossaryFinasteride (fin)

    medication that inhibits DHT to treat hair loss

    Finasteride is a medication primarily used to treat male pattern baldness (androgenetic alopecia) and benign prostatic hyperplasia (BPH). It works by inhibiting the enzyme 5-alpha-reductase, which converts testosterone to dihydrotestosterone (DHT), a hormone linked to hair loss and prostate growth. Commonly known by brand names like Propecia for hair loss and Proscar for BPH, finasteride is taken orally and requires a prescription.
