The exact cause of AA remains unknown, and treatment options are limited and vary in effectiveness among patients. This article reviewed the current understanding of AA's pathogenesis, presenting recent hypotheses and studies to provide a comprehensive view of the potential biological mechanisms behind the disease.

      Hair loss treatments discussed include minoxidil, finasteride, and RU58841. Salon products and supplements generally don't work for hair regrowth unless there's a severe nutritional deficiency, while hormonal treatments like estrogen and spironolactone can be effective.
