research Synthesis and activity of 8-substituted benzo[c]quinolizin-3-ones as dual inhibitors of human 5α-reductases 1 and 2
This study identified potent dual inhibitors of 5α-reductases 1 and 2 that may aid in designing new drugs for related diseases.
research Novel 5α-Reductase Inhibitors: Synthesis, Structure−Activity Studies, and Pharmacokinetic Profile of Phenoxybenzoylphenyl Acetic Acids
In this study, novel substituted benzoyl benzoic acids and phenylacetic acids were potent and selective inhibitors of human steroid 5alpha-reductase type 2, with one compound showing promising bioavailability in rats for potential clinical evaluation.
research Finasteride is the main inhibitor of 5α-reductase activity in microdissected dermal papillae of human hair follicles
Finasteride potentially treats hair loss by reducing DHT production.
research FRI-02 FROM GIRLS TO BOYS TO OLDER MEN, THE INTERESTING TALE OF THE GUEVEDOCES AND 5-ALPHA REDUCTASE INHIBITORS
This historical review traces the discovery of 5-alpha reductase inhibitors, widely used in urology, from the study of guevedoces, Dominican children with a rare disorder leading to significant androgenization at puberty.

5 / 1000+ resultscommunity Androsterone as a Neurosteroid Replacement Strategy for 5α-Reductase Inhibitor–Associated Sexual and Affective Dysfunction
Androsterone may help with sexual and affective dysfunction from finasteride by replacing disrupted neurosteroids without increasing androgenic side effects. Controlled testing is needed to confirm its effectiveness and safety.
community 5 alpha reductase type 1 is in brain tissue producing the main endogenous gabaergic allopregnanolone, not 2. How can finasteride as a 5ar2 lower that?
Finasteride and dutasteride are discussed for hair loss, with concerns about their effects on neurosteroids and potential side effects like depression. Alternatives like topical estrogen and lifestyle changes are considered, with varying opinions on mental health and hair regrowth.
community Allopregnanolone deficiency by 5-ari inhibition (fin/dut users)
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 A better treatment would be a localized 5ar inhibitor that breaks down when it enters blood or leaves hair follicle
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 Does caffeine inhibit 5-α-reductase?
Caffeine may promote hair growth and potentially inhibit 5-α-reductase activity in hair follicles, but its effectiveness and systemic impact remain unclear. Users discuss using topical caffeine solutions, with some experiencing no side effects compared to finasteride.

10 / 15 results- 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.
- 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.
- Is the omega-3 to omega-6 ratio in your diet feeding your hair problem without you knowing? Nutrition sources describe a lopsided omega-6 to omega-3 intake as pro-inflammatory, but no published human study shows that the dietary ratio changes 5-alpha reductase, scalp DHT or hair loss; the one relevant trial tested a commercial omega-3/6 plus antioxidant supplement in 120 women, not a change in dietary fat ratio.
- 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.
- Does metformin help control DHT levels that trigger androgenic alopecia? Metformin has been shown to lower circulating androgens in women with PCOS, but no published study has measured scalp DHT, 5-alpha reductase activity in the follicle, or hair density in anyone taking it — so its effect on pattern hair loss is untested, and it is not a DHT blocker.
