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

in Research/Science 2447 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 Spironolactone for 11 years, finasteride for almost 5 years, started oral minoxidil in November 😢 ended oral contraceptive in Dec.

in Progress Pictures 224 upvotes 8 months ago

A user shared their 11-year experience with spironolactone and nearly 5 years with finasteride for hair loss, recently adding oral minoxidil and stopping birth control. Various treatments were discussed, including organic options, checking for underlying health issues, considering dutasteride, and the potential role of progesterone in hair loss.

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

in Research/Science 449 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 Bile Acid-Mediated DHT Dysregulation Hypothesis

in Research/Science 13 upvotes 1 month 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.
