community Finasteride affects both 5a reductase and 5b reductase

7 upvotes 5 years ago

Finasteride not only inactivates the 5a reductase enzyme but also affects the 5b reductase enzyme in a dose-dependent manner, which can impact sexual behavior and brain activity. The user experienced significant hair regrowth and side effects on 1mg of finasteride, which diminished after reducing the dose to 0.5mg, leading to no side effects and further hair improvement.

community From the research study: "Dihydrotestosterone and the concept of 5a-reductase inhibition in human benign prostatic hyperplasia" - G. Bartsch, R.S. Rittmaster, H. Klocker (2002) in the "World Journal of Urology".

in Research/Science 23 upvotes 2 years ago

Dutasteride is a stronger 5AR inhibitor than finasteride and can significantly lower DHT levels. Reduced doses of dutasteride may lower side effects.

community A repository of links to current scientific research and findings into the nature of and relating to side-effects for Finasteride/Dutasteride/5a-reductase inhibitors.

in Finasteride 17 upvotes 5 years ago

Finasteride and dutasteride, used for hair loss, can cause sexual dysfunction, depression, and suicidal thoughts, with some effects persisting after stopping. The post stresses the importance of being aware of these risks.

community Massive study on finasteride side effects released

in Finasteride/Dutasteride 83 upvotes 1 year ago

The release of a study on 5a-reductase inhibitors (finasteride and dutasteride) which showed an increased risk of depression, dementia, decreased libido, and reduced semen load as potential side effects; discussion around other forms of hair loss treatments such as topical minoxidil, RU58841, or opting to accept baldness; and advice to consider professional help for deeper issues related to hair loss.

community Approximation of Scalp DHT Suppression Between 0.05 mg to 2.5 mg

in Research/Science 63 upvotes 9 months ago

The conversation discusses the effectiveness of various doses of Dutasteride in reducing scalp DHT and its impact on hair count. Users shared personal experiences with hair loss treatments, including Dutasteride, Finasteride, and Minoxidil, with one reporting significant hair loss reduction using a combination of oral Dutasteride and topical Minoxidil and Finasteride.
