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.
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.
The user is experiencing significant hair loss after switching from finasteride to dutasteride for five months. Suggestions include that the hair loss might be a normal shedding phase, with some recommending continuing the treatment for up to 24 months or considering alternatives like RU58841.
The user experienced significant hair regrowth by using a combination of finasteride, oral minoxidil, and later switching to dutasteride. They initially started with finasteride and topical minoxidil, then moved to oral minoxidil and eventually transitioned from finasteride to dutasteride, which they found more effective.
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.
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.
