This study found that finasteride effectively inhibits the enzymatic activity of human steroid 5alphareductasetypeII in newly established CHO cell lines.

In this study, quercetin and kaempferol, two plant-derived flavonoids, showed stronger binding affinities to JAK3 kinase and moderate binding to 5-alphareductasetype 2, suggesting their potential as natural treatments for androgenetic alopecia, with quercetin demonstrating suitable properties for topical application.

This study used molecular docking to analyze the binding affinities of quercetin and kaempferol, plant-derived flavonoids, showing they have promising interaction profiles with JAK3 kinase and moderate binding with 5-alphareductasetype 2, suggesting potential as topical treatments for androgenetic alopecia.
This study details the isolation and characterization of the human typeII5alpha-reductase gene, which may play a role in male pseudohermaphroditism, prostate cancer, and benign prostatic hyperplasia.
FCE 28260 (PNU 156765), an under-explored 5α-reductase inhibitor, showcases promising results in research by Giudici et al., outperforming well-known treatments like Finasteride in reducing the conversion of testosterone to DHT. Its superior efficacy, demonstrated through lower IC50 values in both natural and human recombinant enzyme studies, suggests it could offer more effective management of DHT-related conditions. Additionally, its lower molecular weight hints at better potential for topical application, potentially offering advantages in treating conditions such as androgenic alopecia. Despite its potential, it has not advanced in development, possibly due to financial limitations, leaving its therapeutic prospects and side effect profile largely unexplored.
A 15-year-old is concerned about hair loss, possibly at Norwood 2 or 3, and is using shampoos and conditioners recommended by a trichologist. Suggestions include considering topical minoxidil and consulting a doctor about topical anti-DHT treatments like finasteride or RU58841, but avoiding 5-alpha-reductase inhibitors at this age.
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.
The user regrets stopping finasteride and minoxidil due to increased hair loss. They have resumed these treatments and are considering a hair transplant.
A 66-year-old male experienced significant hair regrowth using topical finasteride for 5 years and oral minoxidil for 3.5 years, with no side effects. He is now switching from finasteride to topical dutasteride while continuing oral minoxidil to potentially improve results further.
Does Procapil block DHT without affecting hormones? What the evidence showsProcapil'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.
