    TLDR A mother and daughter with similar hair loss conditions and identical HLA types suggest a genetic link between the conditions.
    In the 2015 case report, a 67-year-old woman with frontal fibrosing alopecia (FFA) and her 38-year-old daughter with lichen planopilaris (LPP) were examined, revealing identical human leukocyte antigen (HLA) types, which suggests a genetic connection between the two conditions. The mother also had an autoimmune condition not previously associated with FFA. Both patients' treatments resulted in minimal improvement. The report underscores the potential role of genetic, environmental, and hormonal factors in the development of FFA and LPP, but the study's conclusions are limited due to the small sample size of only two participants.

      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 user has been experiencing hair loss for 4 years, with treatments like minoxidil, finasteride, and various supplements proving ineffective. They were diagnosed with fibrosing alopecia in a pattern distribution, a condition that may require a combination of anti-inflammatory and hair growth treatments.

      The user experienced hair loss since 2019 and tried finasteride, dutasteride, RU58841, and ketoconazole shampoo without success. A scalp biopsy showed scarring and inflammation from folliculitis, indicating chronic inflammation was affecting treatment effectiveness.

      The user has been using finasteride, minoxidil, and nizoral for hair loss but hasn't seen regrowth, only maintenance. They are considering switching to dutasteride, which is believed to be more effective, but are concerned about potential side effects.
