    TLDR Low ferritin and vitamin D levels, past infections, stress, and weight changes can trigger hair loss in women.
    The study investigated acute telogen effluvium in 60 women aged 18-45, revealing a high prevalence of ferritin (56.7%) and vitamin D (68.3%) deficiencies. Common triggers included past infections (63.3%), stress (56.7%), and weight changes (28.3%). A significant correlation was found between ferritin levels and the extent of hair loss. The study highlights the need for mandatory screening for these deficiencies in affected women, although it is limited by its small sample size and lack of a control group.
