    TLDR Accurate diagnosis of hair loss types is crucial for effective treatment.
    The document discusses the underdiagnosis of diffuse alopecia areata (AAD), which is often mistaken for telogen effluvium (ET) due to their clinical similarities. AAD, however, has distinct characteristics and requires different therapeutic approaches. The condition is more frequently observed in women and involves an autoimmune mechanism affecting hair follicles in the anagen phase. Diagnosis can be challenging and may require trichoscopy or scalp biopsy. Treatment often involves topical corticosteroids, with a generally favorable prognosis if managed properly. The study emphasizes the importance of considering AAD in differential diagnoses of non-scarring diffuse alopecias.
