    TLDR New treatments for hair loss show promise, but require more research on long-term effects and proper dosing.
    In 2019, the number of patients with frontal fibrosing alopecia had significantly increased. New drugs, such as retinoids, were being explored to halt hair loss progression. Alopecia areata was recognized as significantly impacting patient quality of life, with no FDA-approved treatment at the time. However, Janus Kinase (JAK) inhibitors showed promising results in treating alopecia areata. The side-effect profile of 5α-reductase was a concern for many patients. A study by Rakowska and colleagues found that hair loss progression was halted in 76% of patients using low-dose isotretinoin, 73% in the low-dose acitretin group, and 43% in the finasteride group. Despite these promising treatments, the long-term side effect profile, efficacy, initial regimen treatment, and maintenance dose still needed further evaluation.

      Diffuse hair loss and scalp biopsies

      community Diffuse hair loss and scalp biopsies

      in Research  692 upvotes 4 months ago
      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.

      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.
