    TLDR Infrared thermography, especially with dermoscopy, improves accuracy in diagnosing active hair loss due to inflammation.
    The study, conducted on 22 female patients with Frontal Fibrosing Alopecia (FFA), evaluated the effectiveness of infrared thermography and optical dermoscopy in determining the activity of the inflammatory process in FFA. It found that thermography identified 77% of patients as having active FFA, which was more than the 64% identified through histological assessment. When combined with dermoscopy, the methods achieved a sensitivity of 64%, specificity of 88%, positive predictive value of 90%, and negative predictive value of 58% for diagnosing active FFA. The study concluded that infrared thermography, especially when used alongside dermoscopy, can enhance the accuracy of diagnosing the active phase of FFA, which is essential for appropriate treatment.

      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.

      The user shared their 6-month hair regrowth progress using finasteride, minoxidil, biotin, and iron supplements, along with occasional microneedling and specific shampoos. They reported minimal side effects and no retrograde alopecia, attributing their success to a combination of treatments.

      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.
