5 / 1000+ results research Extensive Challenges and Pending Advances in the Study of 5-Alpha-Reductase Isoenzymes. A Literature Review
In this review, the authors highlight the involvement of the 5α-reductase enzyme family in androgen-dependent disorders, noting the discovery of a novel isoform, SRD5A3, which is overexpressed in cancers with poor prognosis.
research The biochemical and phenotypic characterization of females homozygous for 5 alpha-reductase-2 deficiency.
In this study, females with 5 alpha-reductase-2 deficiency exhibited decreased body hair, normal sebum production, and delayed menarche, suggesting a role for DHT in hair growth and menstrual function.
research Immunolocalization of 5α-Reductase Isozymes in Acne Lesions and Normal Skin
This study found that 5alpha-reductase type 1 localizes specifically to sebaceous glands in both normal and acne follicles, suggesting its role in sebum regulation.
research Synthesis and Biological Evaluation of 4-(4-(Alkyl-and Phenylaminocarbonyl)benzoyl)benzoic Acid Derivatives as Non-steroidal Inhibitors of Steroid 5α-Reductase Isozymes 1 and 2
In this study, 4-(4-(phenylaminocarbonyl)benzoyl) benzoic acid exhibited the strongest inhibitory activity against the human type 2 steroid 5α-reductase isozyme among the compounds tested.

5 / 1000+ resultscommunity Was scared to try fin and jumped straight to 2.5mg Dut?
The user started with oral minoxidil and switched to 2.5mg dutasteride, experiencing significant hair growth without side effects. They believe dutasteride has fewer side effects than finasteride due to its action on both type 1 and 2 5-alpha reductase enzymes.
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.
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 Dutasteride might be better for your hairline. Some people have more type 1 5AR activity in their scalp than others.
Dutasteride might be better for hairline due to varying levels of 5AR activity in scalps. Genetic tests can determine if finasteride is enough or if dutasteride is needed.
community [Research Breakdown] The Genetic Edge: Unpacking Dutasteride vs Finasteride Potency
Dutasteride is more effective than finasteride for increasing hair count, but finasteride is considered safer for long-term use unless hair loss is very aggressive. Starting with finasteride is recommended due to its effectiveness and safety profile.
community Green tea/ soy Isoflavones supplements for MPB
Green tea extract and soy isoflavones may help with hair loss by inhibiting DHT and providing additional health benefits. Combining these with finasteride and possibly using nizoral shampoo could enhance effectiveness in managing hair loss.

10 / 15 results- 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.
- 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.
- 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.
