Estimating the Effect of Finasteride on Kallikrein Marker Levels in Blood and the Use of Converted Markers in the Four-Kallikrein Model

The conversation discusses the need for a localized 5-alpha reductase inhibitor that only affects the scalp without systemic side effects, similar to pyrilutamide's approach. Current treatments like topical liposomal finasteride and dutasteride are mentioned, but concerns about their systemic effects and lack of research are highlighted.

Pattern hair loss before age 35 may be linked to higher risks of prostate cancer, cardiovascular diseases, and metabolic syndrome later in life. Finasteride is discussed as a treatment that may lower PSA levels and potentially prevent prostate issues.

Caffeine may promote hair growth and potentially inhibit 5-α-reductase activity in hair follicles, but its effectiveness and systemic impact remain unclear. Users discuss using topical caffeine solutions, with some experiencing no side effects compared to finasteride.

The user experienced sexual side effects after starting finasteride and later switched to dutasteride, noticing hormonal changes. They are considering using P5P and possibly aromatase inhibitors to manage high prolactin and estradiol levels.

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 helps with hair loss by lowering DHT levels in the scalp, which is more important than blood DHT levels. If finasteride is not effective, consulting a doctor or considering switching to dutasteride may be advisable.
