Glossary3β-Hydroxysteroid Dehydrogenase

enzyme crucial for converting steroid precursors into active hormones

3β-Hydroxysteroid Dehydrogenase (3β-HSD) is an enzyme that plays a crucial role in the biosynthesis of all classes of hormonal steroids, including androgens, estrogens, and glucocorticoids. It catalyzes the conversion of Δ5-3β-hydroxysteroids to Δ4-3-ketosteroids, a key step in the production of hormones that regulate various physiological processes, including hair growth and skin health.

community 3α-Hydroxysteroid dehydrogenase community driven study, not anytime soon guys.

in Research/Science 104 upvotes 3 years ago

High cost of studying 3α-Hydroxysteroid dehydrogenase in hair loss led to suggestions of crowdfunding for research. Users discussed using Procyanidin B2/melatonin topical treatment and tracking funds with blockchain.

community UPDATE: The theory that explains everything. Please help me make this big!

in Research/Science 444 upvotes 3 years ago

Hair loss theory involves 3alpha-hydroxysteroid reductase (3AHD) converting DHT to androstenol. Discussion explores potential treatments and encourages more research.

community The theory that explains everything. Please help me make this big!

in Research/Science 2446 upvotes 3 years ago

The post and conversation are about the role of the enzyme 3alpha-hydroxysteroid reductase in hair loss and the potential of compounds like procyanidin B2 and sulforaphane to boost its activity for hair regrowth. Further research is needed to develop effective treatments based on this theory.

community Bile Acid-Mediated DHT Dysregulation Hypothesis

in Research/Science 13 upvotes 2 weeks ago

Elevated bile acids can inhibit the enzyme AKR1C2, leading to increased DHT levels, which may accelerate hair loss in those predisposed to androgenetic alopecia. Treatments mentioned include topical minoxidil and finasteride.
