July 2026 in “Zenodo (CERN European Organization for Nuclear Research)” This review evaluates the use of 5α-reductase inhibitors in feminising hormone therapy, finding their additive feminising benefits unclear due to their specific action on testosterone conversion, with concerns highlighted regarding limited supporting evidence and safety signals, particularly for psychiatric and sexual effects.
This review concluded that 5α-reductase inhibitors like finasteride and dutasteride offer limited additional feminising effects in hormone therapy for transfeminine individuals, with the clearest use being androgenetic alopecia treatment; more research is needed for other potential benefits.
This study identified CXXC5 as a key mediator of hair loss induced by PGD2 and DHT via suppression of the Wnt/β-catenin pathway, with implications for potential therapeutic targets.
October 2024 in “International Journal of Molecular Sciences” In this study, Rosa rugosa water extract improved hair length and thickness in a mouse model of DHT-induced alopecia by enhancing the expression of hair growth-promoting factors while inhibiting growth-suppressive proteins, suggesting its potential as a natural therapy for hair loss prevention.
9 citations
,
January 2013 in “PubMed” This abstract suggests that finasteride's suppression of DHT may link DHT to migraine causes, or it may benefit migraines by other finasteride properties like testosterone modulation, but reports no new empirical findings.
August 1994 in “Journal of dermatological science” Active oxygen scavengers can reverse the suppression of hair cell growth caused by androgens.
14 citations

January 2000 in “European Urology” This abstract reviews the role of finasteride and potential dual 5alpha-reductase inhibitors in treating benign prostatic hyperplasia, suggesting that dual inhibitors may offer greater DHT suppression and therapeutic advantages, while emphasizing the need for clinical evaluation.
February 2026 in “Archiv Euromedica” In this narrative review, researchers reported that oral finasteride significantly improved hair count and density in male androgenetic alopecia but had higher systemic exposure and potential side effects compared to topical formulations, which provided similar efficacy with lower systemic DHT suppression.
49 citations
,
November 2014 in “Journal of Medicinal Food” In this study, red ginseng extract and its ginsenosides enhanced human hair follicle cell proliferation and countered dihydrotestosterone-induced suppression, suggesting potential to promote hair growth.
15 citations
,
April 2020 in “Journal of The American Academy of Dermatology” In this study, intradermal injection of botulinum toxin was associated with increased hair growth in men with androgenetic alopecia through the suppression of TGF-β1 secretion from dermal papilla cells.

September 2006 in “European Urology Supplements” Dutasteride reduces DHT and improves BPH symptoms more effectively than finasteride.
June 2026 in “Zenodo (CERN European Organization for Nuclear Research)” This review concludes that finasteride and dutasteride are the most evidence-supported oral treatments for androgenetic alopecia, with dutasteride offering slightly greater hair count improvements and both affected by genetic response modifiers.
June 2026 in “Zenodo (CERN European Organization for Nuclear Research)” This study reviews the effectiveness and safety of finasteride and dutasteride for treating androgenetic alopecia, highlighting that dutasteride reduces DHT more deeply than finasteride, with genetic factors influencing patient response and both drugs being evidence-supported options for men and women.
