Telogen Effluvium: Pathogenesis, Clinical Features, Diagnosis, and Management

The document from 8 years ago discussed Telogen effluvium (TE), a common cause of hair loss in women characterized by abrupt shedding of hair due to an early, synchronous entry of hair follicles into the telogen phase. Various triggers such as fever, childbirth, crash diets, thyroid dysfunction, iron deficiency, prolonged anesthesia, chronic illness, and psychological stress/trauma can cause TE. Laboratory testing for ferritin and thyroid-stimulating hormone (TSH) was recommended, as iron deficiency and hypothyroidism were the most common metabolic causes of TE in women. Women with TE could lose more than 300 hairs per day.
