Androgenic alopecia (AGA) might have evolved to reduce prostate cancer risk by increasing UV exposure to the scalp, but this theory is debated. Treatments like minoxidil and finasteride are used for AGA, though the exact causes and evolutionary reasons for hair loss are unclear.
Finasteride increased testosterone and estrogen, stopped hair loss, and promoted regrowth. Users discussed side effects like libido changes and considered adding minoxidil and aromatase inhibitors.
Hair provides protection against head trauma, reduces skin cancer risk, helps remove heavy metals, and aids in wound healing. The conversation emphasizes the health benefits of maintaining head hair beyond cosmetic reasons.
Dutasteride is likely the most effective treatment for male pattern baldness, followed by finasteride and minoxidil in various forms and dosages. Users discuss personal experiences, dosages, and potential side effects, with some considering combining treatments for better results.
Topical finasteride results in plasma levels 100 times lower than oral finasteride, potentially reducing systemic side effects. Users report similar efficacy with fewer side effects, suggesting a preference for topical application.
