Production of 5α-Reduced Neurosteroids Is Developmentally Regulated and Shapes GABA A Miniature IPSCs in Lamina II of the Spinal Cord

research Production of 5α-Reduced Neurosteroids Is Developmentally Regulated and Shapes GABA_AMiniature IPSCs in Lamina II of the Spinal Cord

88 citations , January 2004 in “Journal of Neuroscience”

This study found that inhibiting neurosteroidogenesis affected GABA A receptor-mediated synaptic inhibition in immature rats but not in adults, suggesting age-dependent modulation of synaptic strength in the spinal dorsal horn.

Natural Product-Inspired Bis(Trifluoromethyl) Phenyl Hydroxycinnamate Derivatives as Promising Nonsteroidal Inhibitors of Human Steroid 5α-Reductase Type-1: Synthesis, In Vitro, and In Silico Studies

research Natural Product-Inspired Bis(trifluoromethyl) Phenyl Hydroxycinnamate Derivatives as Promising Nonsteroidal Inhibitors of Human Steroid 5α-Reductase Type-1: Synthesis, In Vitro, and In Silico Studies

August 2025 in “ACS Omega”

This study synthesized and evaluated hydroxycinnamate derivatives for their ability to inhibit human SRD5A1, finding that three compounds showed significant inhibitory activity and low cytotoxicity. Compound 10a notably reduced SRD5A1 protein expression in cells, suggesting potential for nonsteroidal treatment of androgen-related conditions.

Dutasteride, A Novel Dual 5-Alpha Reductase Inhibitor, Reduces Serum DHT to a Greater Extent Versus Finasteride and Achieves Maximal Reduction in a Larger Proportion of Patients

research Dutasteride, a novel dual 5-A reductase inhibitor, reduces serum DHT to a greater extent versus finasteride and achieves finasteride maximal reduction in a larger proportion of patients

12 citations , February 2003 in “European Urology Supplements”

Dutasteride reduces DHT more effectively than finasteride.

Targeting JAK/STAT and Wnt/Beta-Catenin Pathways and 5-Alpha-Reductase Activity to Develop an Effective Anti-Hair Loss Product

research 570 Targeting JAK/STAT and Wnt/b-catenin pathways and 5a-reductase activity to develop an effective anti-hair loss product

November 2022 in “Journal of Investigative Dermatology”

This study found that a lotion containing specific plant extracts significantly increased the number of anagen hairs and the anagen/telogen ratio in subjects with androgenetic alopecia after three months of use.

In Vitro and In Vivo Regulation of SRD5A mRNA Expression of Supercritical Carbon Dioxide Extract from Asparagus Racemosus Root as Anti-Sebum and Pore-Minimizing Active Ingredients

research In Vitro and In Vivo Regulation of SRD5A mRNA Expression of Supercritical Carbon Dioxide Extract from Asparagus racemosus Willd. Root as Anti-Sebum and Pore-Minimizing Active Ingredients

8 citations , February 2022 in “Molecules”

This study found that Asparagus racemosus root extract significantly reduced facial sebum production and pore size in male volunteers, suggesting potential application as an anti-sebum ingredient in cosmetics.

community Supposedly dairy contains precursors to DHT that are already 5a-reduced and convert to DHT independent of 5a-reductase inhibition

26 upvotes 5 months ago

Dairy may contain DHT precursors that could affect hair loss and prostate health, with some users noting reduced hair shedding after eliminating dairy. Individual responses to dairy and DHT blockers vary, with some attributing hair health to diet changes and others seeing no impact.

community Explanation for "dutasteride destroyed my hair"

7 upvotes 2 years ago

Dutasteride can drastically reduce sebum production, leading to dryer hair and shedding. Alternating shampoos and periodic silica supplementation can improve hair quality and thickness.

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.

in Research/Science 9 upvotes 3 years ago

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 Finasteride does deplete important nuero-active steroids

11 upvotes 3 years ago

Finasteride can reduce neuroactive steroids, causing side effects like depression, anxiety, and sexual dysfunction. Some users experience persistent symptoms after stopping finasteride, while others use alternative treatments like topical solutions.

community Dutasteride absolutely nukes hair DHT

in Finasteride/Dutasteride 486 upvotes 1 year ago

Dutasteride significantly reduces DHT levels, potentially more effectively than finasteride, and is used to treat hair loss. Some users report side effects like reduced libido and mood changes, while others experience hair regrowth and increased testosterone.
