Impact of Low Dose Finasteride for the Treatment of Androgenic Alopecia on Serum Prostate Specific Antigen Levels in Men Participated in Population-Based Screening for Prostate Cancer

A 30-year-old man experienced significant hair regrowth and improved libido after using finasteride and dutasteride for androgenetic alopecia, with no adverse effects. He plans to reduce dutasteride dosage when trying to conceive and has been using topical minoxidil since 2015.

Finasteride may affect prostate sensation and size, with some users reporting easier urination. Concerns exist about prostate shrinkage even at lower doses.

A 27-year-old male physician improved hair density using minoxidil 5% foam and finasteride 1mg every other day, with initial sexual side effects that subsided. He recommends trying finasteride for a year but warns against dutasteride due to potential liver effects.

Dutasteride is recommended for men on testosterone replacement therapy (TRT) with DHT-sensitive hair, as it does not interfere with TRT's anabolic effects and may improve libido and aging male symptoms. Users report varying experiences with libido when switching from finasteride to dutasteride, with some noticing improvements and others experiencing fluctuations.

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.

Finasteride and dutasteride are essential for stopping hair loss, while natural remedies are ineffective. Minoxidil can be added if needed, but blocking DHT is crucial.
