    Glossary 5α-reductase inhibition

    blocking enzyme that converts testosterone to hair-loss hormone DHT

    5α-reductase inhibition refers to the process of blocking the enzyme 5α-reductase, which is responsible for converting testosterone into dihydrotestosterone (DHT). DHT is a hormone that can contribute to hair loss and conditions like benign prostatic hyperplasia. By inhibiting this enzyme, medications like finasteride and dutasteride can help reduce hair loss and treat these conditions.
