GlossaryAldo-Keto Reductase Family 1 Member C3 (AKR1C3)

enzyme involved in hormone metabolism affecting hair growth and alopecia

Aldo-Keto Reductase Family 1 Member C3 (AKR1C3) is an enzyme that plays a crucial role in the metabolism of steroids, prostaglandins, and other compounds. It is involved in the conversion of hormones like testosterone and estrogen, which can influence various physiological processes, including hair growth and the development of conditions like alopecia.

community DHT levels after 4 weeks of Fina and 8 weeks of Fina + 4 weeks of Duta

in Update 35 upvotes 5 years ago

The user reported early stage diffuse hair thinning and increased DHT levels after 4 weeks on Finasteride and 8 weeks on Finasteride plus 4 weeks on Dutasteride, despite the medications being authentic and stored properly. They are considering increasing their Dutasteride dosage due to the lack of side effects and are unsure if the treatment is helping their hair.

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.

community Switched from finasteride to dutasteride - 2 month update

in Finasteride/Dutasteride 6 upvotes 1 year ago

The user switched from finasteride to dutasteride for hair loss treatment, but experienced increased libido, itchy scalp, and accelerated hair loss. Another user suggested that genetic variations might cause dutasteride to be less effective and recommended checking for specific genetic markers.
