    TLDR Trichoscopy and pathological examination both have unique benefits and cannot completely replace each other in evaluating hair.
    The study "Comparison Between Trichoscopic and Histopathological Evaluations of Hair Parameters" conducted a cross-sectional study on 30 volunteers to compare the efficacy of trichoscopy and pathologic examination in hair counting. The study found that hair densities varied across different scalp regions, with the highest density in the vertex region. The occipital region had a hair density of 163.07±28.17/cm2, a vellus ratio of 6.60±3.95%, and a hair shaft diameter of 74.52±8.02μm. Some volunteers showed pathologic features of androgenetic alopecia (AGA) in occipital areas, suggesting that AGA can affect this area even in early stages. The study concluded that both trichoscopy and pathological examination have their advantages and disadvantages, and the data obtained from these two methods are different to some extent, which cannot be substituted entirely for each other.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      A user in France is frustrated because three dermatologists refused to prescribe finasteride for their hair loss, suggesting it's not androgenetic alopecia (AGA) and offering expensive vitamin treatments instead. Other users suggest buying hair loss treatments like minoxidil and finasteride from various online pharmacies and considering a gender-affirming care physician for more understanding treatment options.

      The user noticed potential hair growth after 13 days of using RU58841, alongside a regimen of oral minoxidil, finasteride, and topical minoxidil. Others think it's too soon to see results, and some are surprised by the high dosage of oral minoxidil.

      The user was diagnosed with DUPA and initially treated with finasteride, then switched to dutasteride which worsened their hair loss. They are now returning to finasteride and adding treatments including oral minoxidil, Proscar, Viviscal, pumpkin seed oil, LLLT, and Nizoral shampoo, hoping for hair regrowth.
