Did you mean Dihydrotestosterone Blockers?

Glossary Dihydrotestosterone Blockers

inhibit the hormone DHT to prevent hair loss

Dihydrotestosterone Blockers, often referred to as DHT Blockers, are substances that inhibit the action or production of dihydrotestosterone (DHT), a hormone linked to hair loss. By reducing DHT levels, these blockers can help prevent hair follicles from shrinking, thereby slowing or stopping hair loss and promoting hair regrowth.

research COMBINATION OF AN ANTIANDROGEN AND A 5α-REDUCTASE INHIBITOR: A FURTHER STEP TOWARDS TOTAL ANDROGEN BLOCKADE?

9 citations , March 1991 in “Endocrinology”

This study in rats suggests that combining the 5 alpha-reductase inhibitor 4-MA with the antiandrogen Flutamide may enhance prostate cancer therapy by additively inhibiting prostatic growth and mRNA levels of androgen-sensitive prostatic binding proteins.

research Triple Hormonal Blockade (ADT3): A Patient’s Perspective

January 2019 in “Oncogen”

This report suggests that for prostate cancer patients with cardiovascular disease, prescribing the GnRH antagonist degarelix may reduce cardiac events compared to using GnRH agonists, although prescribing should consider potential cardiac risks, particularly in patients with pre-existing conditions or older age.

research Androgen Receptor Blockade Induces the Phagocytosis of MRSA and Pseudomonas aeruginosa by Monocyte-Derived Macrophages In Vitro

September 2025 in “Deleted Journal”

This study found that in vitro environments simulating testosterone levels in elderly males, testosterone and its metabolite DHT significantly reduced macrophages' ability to phagocytize MRSA and Pseudomonas aeruginosa, suggesting AR manipulation and inhibiting testosterone-DHT conversion might help fight wound infections in the elderly.

learn Bicalutamide

Can bicalutamide stop DHT from shrinking your hair follicles? Bicalutamide blocks androgens at the receptor rather than lowering DHT, and some dermatologists prescribe it off-label for women with pattern hair loss. The published evidence is retrospective case series and one small pilot study, with no randomized trial; it is a prescription drug that requires liver monitoring and is contraindicated in pregnancy.

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.

community Finasteride and Eye Problems: You’re Not Going Crazy

in Finasteride/Dutasteride 503 upvotes 1 year ago

Finasteride can cause dry eyes and vision issues due to its impact on the meibomian glands. Users have mixed experiences, with some experiencing eye discomfort and others having no side effects.

community Increased adipose tissue (being overweight) in males may increase likelyhood of finasterde side effects

in Research/Science 29 upvotes 2 years ago

Being overweight may increase finasteride side effects due to higher aromatase activity converting testosterone to estradiol. Maintaining a healthy weight could reduce these side effects.

community Topical Finasteride Doesn't Directly Reduce 5ar Enzyme on Scalp

in Finasteride/Dutasteride 72 upvotes 3 years ago

Topical Finasteride doesn't directly reduce 5ar enzyme on scalp and has the same mechanism as oral, needing to go through the liver. Users debate the accuracy of this information and discuss various studies and experiences.

community How is dht not beneficial to you?

in Finasteride/Dutasteride 111 upvotes 7 months ago

DHT is important for sexual function and mood, but finasteride and dutasteride can reduce DHT, causing side effects like reduced libido and erectile dysfunction. These treatments are effective for hair loss, but their impact on DHT leads to debate.
