    TLDR The conclusion is that a new method could improve the identification of autoimmune targets in alopecia areata, despite some limitations.
    The document from 2018 discussed the development of an unbiased, large-scale screening method to identify antigen epitopes in autoimmune diseases, specifically focusing on alopecia areata (AA). It highlighted the limitations of traditional methods for identifying autoantigens and proposed the use of the Immune Epitope Database and Analysis Resource (IEDB) for high-throughput epitope prediction from hair follicle proteins. The goal was to validate these predictions using peripheral blood mononuclear cells from AA patients to identify true, disease-associated autoantigen epitopes. However, the document acknowledged that this method might not capture all disease-associated epitopes and could be biased toward certain cytokines and T-cell subsets. Despite these limitations, the document emphasized the potential of this approach to improve the identification and validation of autoantigen epitopes in AA.

      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 redh0t12 suggests using a derma pen for hair regrowth, as it helped them after using finasteride and minoxidil. Others discuss their experiences with various treatments, including derma rolling, oral and topical minoxidil, and finasteride, with mixed results.

      A user did not respond to finasteride, dutasteride, and oral minoxidil for hair loss after four years of treatment and is considering scalp micropigmentation (SMP). Other users suggest the hair loss pattern may indicate alopecia areata and recommend seeing a dermatologist.

      A 22-year-old male has been experiencing widespread hair loss for over four years, including pain and significant shedding. Treatments tried include ketoconazole shampoo, fluocinonide topical solution, biotin, ACV, and dry shampoo, but none have been effective.
