Expression of Type 1 5α-Reductase and Metabolism of Testosterone in Reconstructed Human Epidermis: A New Model for Screening Skin-Targeted Androgen Modulators

research Expression of type 1 5α-reductase and metabolism of testosterone in reconstructed human epidermis (SkinEthic®): a new model for screening skin-targeted androgen modulators

3 citations , December 2000 in “International Journal of Cosmetic Science”

This study established that a human epidermal model can be utilized to assess 5alpha-reductase activity and evaluate enzyme modulators, such as finasteride, for dermatological applications.

research LY191704: a selective, nonsteroidal inhibitor of human steroid 5 alpha-reductase type 1.

53 citations , June 1993 in “Proceedings of the National Academy of Sciences of the United States of America”

This study identified LY191704 as a specific noncompetitive inhibitor of human 5 alpha-reductase type 1, which may be useful in treating endocrine disorders related to DHT overproduction.

Human Type 3 5α-Reductase Is Expressed in Peripheral Tissues at Higher Levels Than Types 1 and 2 and Its Activity Is Potently Inhibited by Finasteride and Dutasteride

research Human type 3 5α-reductase is expressed in peripheral tissues at higher levels than types 1 and 2 and its activity is potently inhibited by finasteride and dutasteride

45 citations , August 2010 in “Hormone Molecular Biology and Clinical Investigation”

This study found that SRD5a-3 is a highly efficient enzyme for converting hormones into androgens, with dutasteride being a much more potent inhibitor of SRD5a-3 than SRD5a-2.

research Activity of type 1 5α-reductase is greater in the follicular infrainfundibulum compared with the epidermis

12 citations , February 1997 in “British Journal of Dermatology”

This study found that 5α–reductase activity is higher in infrainfundibular keratinocytes compared to interfollicular epidermal keratinocytes, suggesting a potential role in acne-related follicular changes.

Effect of MK-386, a Novel Inhibitor of Type 1 5 Alpha-Reductase, Alone and in Combination with Finasteride, on Serum Dihydrotestosterone Concentrations in Men

research Effect of MK-386, a novel inhibitor of type 1 5 alpha-reductase, alone and in combination with finasteride, on serum dihydrotestosterone concentrations in men.

6 citations , August 1996 in “The Journal of Clinical Endocrinology and Metabolism”

MK-386 and finasteride together effectively reduce DHT levels, potentially treating acne and male pattern baldness.

community 5 alpha reductase type 1 is in brain tissue producing the main endogenous gabaergic allopregnanolone, not 2. How can finasteride as a 5ar2 lower that?

27 upvotes 1 year ago

Finasteride and dutasteride are discussed for hair loss, with concerns about their effects on neurosteroids and potential side effects like depression. Alternatives like topical estrogen and lifestyle changes are considered, with varying opinions on mental health and hair regrowth.

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.

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 Was scared to try fin and jumped straight to 2.5mg Dut?

36 upvotes 1 week ago

The user started with oral minoxidil and switched to 2.5mg dutasteride, experiencing significant hair growth without side effects. They believe dutasteride has fewer side effects than finasteride due to its action on both type 1 and 2 5-alpha reductase enzymes.

community We need actual hair loss studies on Epristeride

in Research/Science 6 upvotes 1 year ago

Epristeride is a selective 5 alpha reductase type 2 inhibitor that may reduce scalp DHT similarly to finasteride, with potentially fewer side effects. It is suggested that combining epristeride with finasteride or dutasteride could enhance hair loss treatment effectiveness.

community Day 1 vs Day 168 (today) of defeating the norwood reaper

1528 upvotes 2 years ago

The user achieved significant hair regrowth using topical 5% minoxidil and oral 1mg finasteride daily, especially around the temples. They experienced minimal side effects, with initial difficulty maintaining erections that resolved after a few weeks.
