    TLDR Alopecia areata involves specific T-cells, unlike androgenetic alopecia.
    Alopecia areata (AA) is an autoimmune disorder characterized by a restricted and oligoclonal T-cell receptor-repertoire among infiltrating lymphocytes, while androgenetic alopecia (AGA) is not. This suggests that T cells play a significant role in AA, but not in AGA. The study involved small sample sizes of patients with AA and AGA, and further research is needed to confirm these findings. The restricted T-cell receptor repertoire in AA may lead to the development of targeted therapies for the disease.

      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.

      A 29-year-old woman is experiencing gradual hair thinning since age 15, suspects Androgenic Alopecia, and has tried 5% minoxidil with little success. She has purchased various hair loss treatments including minoxidil, dutasteride, finasteride, and spironolactone, but is cautious about starting them due to potential interactions with her ADHD medication.

      The conversation discusses Fevipiprant, an asthma drug that may block CRTH2 and potentially stop male pattern baldness (MPB) without inhibiting DHT. It also mentions the use of finasteride and dutasteride for hair loss.

      Key treatments for hair preservation include minoxidil, finasteride/dutasteride, and microneedling, with additional options like specific shampoos, oils, biotin, zinc, tretinoin, clascoterone, and low-level laser therapy. Maintaining a healthy lifestyle, reducing stress, and addressing nutrient deficiencies can also support hair health.
