    TLDR Stress, nutritional issues, and chronic diseases can cause hair loss, and nail changes may signal internal diseases; treatment focuses on the underlying cause.
    The 2009 document discusses various hair and nail disorders, highlighting telogen effluvium as a condition caused by stressors that disrupt the normal hair cycle, potentially leading to chronic shedding. It notes that nutritional deficiencies and chronic diseases can contribute to hair loss, with treatments focusing on correcting the underlying trigger and supporting hair regrowth. The document also addresses anagen effluvium, thyroid-related hair loss, pattern hair loss, and hirsutism, suggesting treatments like topical minoxidil and antiandrogen medications. Additionally, it mentions that hair shaft changes and scarring alopecia can indicate systemic conditions, and nail disorders may reflect internal diseases. The importance of diagnosing systemic diseases in patients with hair and nail symptoms is emphasized, and the document provides insight into the pathology of hair loss, the effects of various factors on hair follicles, and the diagnostic value of changes in hair and nails.

      research Proceedings of the Ninth World Congress for Hair Research 2015

      January 2017 in “Journal of Investigative Dermatology Symposium Proceedings”
      The 2015 Hair Research Congress concluded that stem cells, maraviroc, and simvastatin could potentially treat Alopecia Areata, topical minoxidil, finasteride, and steroids could treat Frontal Fibrosing Alopecia, and PTGDR2 antagonists could also treat alopecia. They also found that low-level light therapy could help with hair loss, a robotic device could assist in hair extraction, and nutrition could aid hair growth. They suggested that Alopecia Areata is an inflammatory disorder, not a single disease, indicating a need for personalized treatments.
