Finasteride affects both 5a reductase and 5b reductase 8/15/2019

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.

The conversation discusses the side effects of finasteride, including low libido and erectile dysfunction, and the possibility of these effects being permanent, known as post-finasteride syndrome (PFS). Some users report personal experiences with PFS and debate whether the condition is real, with varying opinions on the reversibility of side effects and the role of individual biology.
community The Finasteride Shed is real.
Increasing finasteride dosage can cause significant hair shedding initially. Users suggest adding minoxidil or switching to dutasteride for better results.
community Dutasteride questions
Switching to dutasteride as a hair loss prevention treatment, along with minoxidil, dermarolling and nizoral shampoo, and the potential benefits and side effects of using finasteride and/or dutasteride in combination with topical anti-androgens like RU58841.
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.
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 Increased adipose tissue (being overweight) in males may increase likelyhood of finasterde side effects
Being overweight may increase finasteride side effects due to higher aromatase activity converting testosterone to estradiol. Maintaining a healthy weight could reduce these side effects.
