Changes in Urine Androgen and Prostaglandin Levels During Finasteride Treatment

Finasteride is effective for treating male pattern baldness (MPB) with minimal side effects, and topical finasteride is similarly effective. Dutasteride is also effective but less understood, and Minoxidil is less effective than Finasteride.

A 25-year-old male experienced significant hair loss due to telogen effluvium and androgenetic alopecia. He began using finasteride, minoxidil, and vitamins, seeing some regrowth but remains worried about hair density.

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.

A 25-year-old male using 1mg Finasteride and 5% Minoxidil for hair loss experienced stabilized scalp hair but began noticing beard shedding. Users suggest that Finasteride can slow beard growth, and some recommend using Minoxidil on the beard to counteract thinning.

A 40-year-old man experiencing male pattern baldness reports noticeable hair regrowth after 6 weeks of using finasteride 1 mg daily, topical minoxidil 5% twice a day, and ketoconazole shampoo twice a week. He has not experienced any side effects and plans to continue monitoring his progress.

Finasteride's effectiveness and side effects may vary based on male phenotypes, with some users noting differences in response related to body and facial hair characteristics. Some users report success with lower doses, while others experience side effects, suggesting individual variability in response to the treatment.
