    TLDR A new method improves alopecia diagnosis using non-invasive steps.
    The study introduces a novel three-step diagnostic algorithm for alopecia that integrates clinical and trichoscopic features to improve diagnosis accuracy while reducing the need for invasive procedures. The algorithm begins by categorizing alopecia based on distribution (patchy, patterned, or diffuse), then distinguishes between scarring and non-scarring types by examining follicular ostia, and finally identifies specific trichoscopic patterns. This approach enhances the ability to diagnose alopecia subtypes confidently using non-invasive trichoscopy.

      community Testosterone and hair loss seeming irrelevance

      in Research/Science  80 upvotes 2 years ago
      The conversation is about the role of testosterone in hair loss and the effectiveness of different treatments. The conclusion is that DHT is the main culprit for hair loss, and finasteride has been proven to work long-term in maintaining and regrowing hair. Testosterone may have a minor effect, but it is not the primary cause of hair loss.

      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.
