PSA Concentration Change in Men Taking Low Dose Finasteride and Dutasteride for Male Androgenetic Alopecia

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.

Dutasteride improved hair density and thickness in men who didn't respond to finasteride, with some experiencing transient sexual dysfunction. Users discussed switching from finasteride to dutasteride, noting initial shedding but eventual hair improvement.

A user discovered they have naturally low DHT levels and is concerned about taking finasteride, which could further lower these levels. They are seeking advice on whether to proceed with the treatment given their hormone levels are within the normal range.

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.

A user reported a significant reduction in DHT levels after 3 months of taking 1mg/day oral finasteride, along with using minoxidil foam, microneedling, and Nutrafol vitamins. They hope this will lead to hair growth and less shedding.

The efficacy of low doses of finasteride to reduce scalp DHT, and whether studies showing a 61% reduction are reflected in actual results. Replies discussed hair growth as an unintended consequence of minoxidil and finasteride use, as well as self-selective bias, potential side effects, and that studies measure effectiveness by hair count changes rather than DHT inhibition.
