This is a list of 5α-reductase inhibitors (5α-RIs), drugs which inhibit one or more isoforms of the enzyme 5α-reductase.This enzyme is responsible for the conversion of the androgen hormone testosterone into the more potent dihydrotestosterone (DHT) and is essential for the production of neurosteroids like allopregnanolone, tetrahydrodeoxycorticosterone (THDOC), and 3α-androstanediol from ...
Saw palmetto is a natural DHT blocker that’s extracted from a palm plant called Serenoa repens. ... Biotin, or vitamin B7, is a water-soluble vitamin found in certain foods. It’s also a ...
Pumpkin seed oil: If you want to keep things super natural, use a product with pumpkin seed oil—the natural oil blocks testosterone from converting into DHT, which prevents hair loss and thinning.
5α-Reductase inhibitors (5-ARIs), also known as dihydrotestosterone (DHT) blockers, are a class of medications with antiandrogenic effects which are used primarily in the treatment of enlarged prostate and scalp hair loss. They are also sometimes used to treat excess hair growth in women and as a component of hormone therapy for transgender ...
Finasteride (Proscar or Propecia) was the first steroidal 5α-reductase inhibitor approved by the U.S. Food and Drug Administration (USFDA). It inhibits the function of two of the isoenzymes (type II and III). [4] In human it decreases the prostatic DHT level by 70–90% and reduces the prostatic size. [1]
DHT, also known as 5α-androstan-17β-ol-3-one, is a naturally occurring androstane steroid with a ketone group at the C3 position and a hydroxyl group at the C17β position. It is the derivative of testosterone in which the double bond between the C4 and C5 positions has been reduced or hydrogenated .

This is the mechanism of 5α-reductase on testosterone to convert it into DHT (dihydrotestosterone). 5α-Reductase works by using the reducing power of NADPH to perform a hydride shift on the double carbon bond in the ring causing enolate formation and subsequent tautamerization to form DHT.
