    TLDR Perifollicular erythema can indicate active frontal fibrosing alopecia.
    The study evaluated 79 women diagnosed with frontal fibrosing alopecia (FFA) and found that 100% exhibited at least one dermoscopic sign typical of FFA, such as absence of follicular opening, follicular hyperkeratosis, follicular plugs, and erythema. Specifically, 66.3% showed perifollicular erythema, which was present in 95% of cases with active disease. The findings suggested that perifollicular erythema could serve as a direct marker of FFA activity.

      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.

      Topical finasteride and minoxidil are not effective for the user, who is considering switching to oral treatments like finasteride or dutasteride. Many suggest oral medications are more effective, and some recommend additional treatments like microneedling and other topical solutions.

      community Testosterone and hair loss seeming irrelevance

      in Research/Science  82 upvotes 1 year 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 25-year-old with AGA experienced hair thinning and dandruff, stabilized with topical finasteride and minoxidil but saw minimal regrowth. They seek advice on styling and consider oral minoxidil and microneedling for denser hair.
