    TLDR Frontal fibrosing alopecia mainly affects postmenopausal women and may be linked to thyroid hormones.
    The study on 490 cases of frontal fibrosing alopecia (FFA) revealed that 95% of the patients were female, predominantly postmenopausal. The age of onset ranged from 15 to 89 years, with diagnosis delays up to 24 years. Thyroid disorders were common, affecting 13% of men and 35% of women, while abnormal blood lipid levels were found in 42% of men and 47% of women. Lower disease activity was correlated with abnormal testosterone and estrogen levels, and the use of face cleaning products, hair colorants, and hairspray. The findings suggested a potential role of thyroid hormones in FFA pathogenesis and indicated that leave-on cosmetic products might not contribute to the disease. Further studies were recommended to explore these associations.

      Diffuse hair loss and scalp biopsies

      community Diffuse hair loss and scalp biopsies

      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.

      community Where to Begin with Microneedling?

      in Treatment  17 upvotes 1 year ago
      User is considering microneedling to enhance hair regrowth after limited response to minoxidil and better results with finasteride and ketoconazole shampoo. Recommendations include using a 1.5mm derma roller once a week, avoiding minoxidil on microneedling days, and disinfecting the roller with isopropyl alcohol.
