Glossary 5-alpha-reductase inhibitor

blocks enzyme converting testosterone to dihydrotestosterone (DHT)

A 5-alpha-reductase inhibitor is a type of medication that blocks the enzyme 5-alpha-reductase, which is responsible for converting testosterone into dihydrotestosterone (DHT). By reducing DHT levels, these inhibitors can help treat conditions like male pattern baldness and benign prostatic hyperplasia (BPH).

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 9 upvotes 3 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.

community Allopregnanolone deficiency by 5-ari inhibition (fin/dut users)

in Finasteride/Dutasteride 11 upvotes 2 years ago

The conversation is about managing allopregnanolone deficiency caused by 5-alpha-reductase inhibitors like finasteride or dutasteride. Specific treatments discussed for hair loss include Minoxidil, finasteride, and RU58841.

community Which Saw Palmetto is good for blocking 5 alpha reductase, Serenoa repens or Chamaerops humilis?

6 years ago

The conversation is about determining which type of Saw Palmetto, either Chamaerops humilis or Serenoa repens, is effective for inhibiting the 5 alpha reductase enzyme related to hair loss. Specific treatments mentioned are Minoxidil, finasteride, and RU58841.

community A better treatment would be a localized 5ar inhibitor that breaks down when it enters blood or leaves hair follicle

1 upvotes 1 year ago

The conversation discusses the need for a localized 5-alpha reductase inhibitor that only affects the scalp without systemic side effects, similar to pyrilutamide's approach. Current treatments like topical liposomal finasteride and dutasteride are mentioned, but concerns about their systemic effects and lack of research are highlighted.

community We need actual hair loss studies on Epristeride

in Research/Science 6 upvotes 1 year ago

Epristeride is a selective 5 alpha reductase type 2 inhibitor that may reduce scalp DHT similarly to finasteride, with potentially fewer side effects. It is suggested that combining epristeride with finasteride or dutasteride could enhance hair loss treatment effectiveness.

learn procapil

Want to stop hormonal hair loss without touching your hormone levels? Procapil could block the enzyme doing the damage. Procapil's supplier describes it as inhibiting 5-alpha reductase at the scalp without changing hormone levels, but the published support is cell and animal work plus one small human study of a caffeine-plus-Procapil formula. It is a cosmetic ingredient, not an approved hair-loss treatment, and no trial has compared it with finasteride or minoxidil.

learn Fluridil

How is Fluridil different from other DHT blockers like finasteride? Fluridil is a topical androgen-receptor blocker applied to the scalp, while finasteride is an oral 5-alpha-reductase inhibitor that lowers DHT throughout the body. Finasteride is FDA-approved and far better studied; Fluridil rests on one 43-man trial and is not licensed as a hair-loss medicine, so its long-term safety and effect size are unknown.

learn Ecklonia Cava

Can Ecklonia Cava be used as a preventive treatment for early signs of hair thinning? No human trial has tested Ecklonia cava for hair loss, so it cannot be called preventive; the evidence is mouse studies and cell cultures suggesting antioxidant activity and 5-alpha-reductase inhibition in the lab.
