Did you mean 5a-reductase?

Glossary5α-reductase

enzyme converting testosterone into potent dihydrotestosterone (DHT)

5α-reductase is an enzyme that converts testosterone into dihydrotestosterone (DHT), a more potent androgen hormone. This enzyme plays a significant role in various biological processes, including the development of male characteristics and the regulation of hair growth. Inhibitors of 5α-reductase, such as finasteride, are commonly used to treat conditions like male pattern baldness and benign prostatic hyperplasia.

community Did anybody use beta sisterol for hair loss? I saw in many articles in the internet that said that beta sisterol blocks dht by inhibiting 5a reductase type 2 enzyme and some reviews of people who said that it worked better than saw palmetto in terms of stoping hair loss and helping prostate.

in Research/Science 8 upvotes 2 years ago

Beta-sitosterol may inhibit 5-alpha reductase type 2 enzyme, potentially reducing DHT levels and promoting hair growth, similar to finasteride but possibly with fewer side effects. Its effectiveness and side effects compared to other treatments like saw palmetto and finasteride remain uncertain due to limited research.
