Genetic Analysis of 5 Alpha Reductase Type 2 Enzyme in Relation to Oxidative Stress in Cases of Androgenetic Alopecia in a Sample of Egyptian Population

research Genetic analysis of 5 α reductase type 2 enzyme in relation to oxidative stress in cases of androgenetic alopecia in a sample of egyptian population

1 citations , October 2013 in “Our Dermatology Online”

This study found that individuals in this Egyptian cohort carrying the leucine (L) allele of the 5-α reductase type II enzyme had a higher risk of developing androgenetic alopecia, which may be associated with oxidative stress.

research Expression and Activity Assay of Human Steroid 5 Alpha-Reductase Type II in CHO Cells

January 2004 in “Pharmaceutical biotechnology”

This study found that finasteride effectively inhibits the enzymatic activity of human steroid 5 alpha reductase type II in newly established CHO cell lines.

research Determination of the potency of a novel saw palmetto supercritical CO2 extract (SPSE) for 5α-reductase isoform II inhibition using a cell-free in vitro test system

3 citations , April 2016 in “Research and reports in urology”

In a cell-free test setting, this study found that a novel saw palmetto extract effectively inhibited the 5α-reductase type II enzyme, showing promising bioactivity comparable to finasteride for promoting prostate health.

Synthesis and 5α-Reductase Inhibitory Activity of 8-Substituted Benzo[ƒ]Quinolinones Derived from Palladium Mediated Coupling Reactions

research Synthesis and 5α-reductase inhibitory activity of 8-substituted benzo[ƒ]quinolinones derived from palladium mediated coupling reactions

14 citations , February 1998 in “Bioorganic & Medicinal Chemistry Letters”

This study explored how modifying the 8-substituent of 8-bromobenzoquinolinone affects its selectivity in inhibiting both 5 alpha-reductase isozymes in the scalp.

research Extract of Plumbago zeylanica enhances the growth of hair follicle dermal papilla cells with down‐regulation of 5α‐reductase type II

4 citations , March 2020 in “Journal of Cosmetic Dermatology”

This study found that Plumbago zeylanica extract and its component plumbagin may help prevent androgenetic alopecia by promoting dermal papilla cell growth and reducing SRD5A2 expression.

community Dutasteride might be better for your hairline. Some people have more type 1 5AR activity in their scalp than others.

in Finasteride/Dutasteride 52 upvotes 3 years ago

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.

community 5 years on topical finasteride, 3.5 years on oral minoxidil; now changing from finasteride to dutasteride

133 upvotes 2 weeks ago

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.

community UPDATE: now 5 months on Dut and continuing to regress aggressively

in Finasteride/Dutasteride 218 upvotes 1 year ago

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.

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 Finasteride is a risk in pregnancy with unprotected sex

118 upvotes 6 years ago

Finasteride may pose a risk during pregnancy, so using a condom is recommended if a partner is pregnant. It is advised to stop finasteride before trying to conceive due to potential effects on fetal development.
