    Glossary5α-reductase inhibitors (5ARIs)

    block enzyme converting testosterone to hair-loss-causing DHT

    5α-reductase inhibitors, also known as 5-ARIs, are medications that block the enzyme 5α-reductase. This enzyme converts testosterone into dihydrotestosterone (DHT), a hormone that can contribute to conditions like male pattern baldness and benign prostatic hyperplasia (BPH). By inhibiting this enzyme, 5-ARIs can help reduce hair loss and shrink an enlarged prostate.

      Topical Dutasteride - Non-Hormonal, Side Effect Free 5ARI?

      community Topical Dutasteride - Non-Hormonal, Side Effect Free 5ARI?

      Topical dutasteride is suggested as a low side-effect treatment for hair loss, with a proposed dose of 0.025% 1ml/day. It is considered better than finasteride due to its even inhibition of DHT isoforms and lower systemic absorption.
