    TLDR Frontal Fibrosing Alopecia might be an autoimmune disease.
    The document from 2019 discusses Frontal Fibrosing Alopecia (FFA), a condition primarily affecting postmenopausal Caucasian women, characterized by hairline regression and scarring. It proposes that FFA may be an autoimmune disease, citing evidence such as lymphocytic infiltrates, association with other autoimmune disorders, and response to immunomodulatory drugs. Out of 921 reported cases, only 29 were male, supporting the hypothesis that hypoandrogenism could be a factor, given FFA's prevalence in postmenopausal women with reduced DHEA serum levels. The document also notes that future research should investigate the autoimmune origin of FFA, with one study including 1083 patients and another involving biopsies from five patients with FFA.

      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 is concerned that finasteride isn't working for their hair loss, questioning if it's due to male pattern baldness or low iron levels. They are advised to take finasteride daily and get blood work done.
