TLDR Lower iron levels are linked to longer hair loss.
The study conducted at Dhaka Medical College in 2017 investigated the relationship between serum iron levels and the duration of hair loss in 35 newly diagnosed alopecia patients, compared to 35 healthy controls. The participants, aged 18 to 45, were divided into two groups based on the duration of hair loss: ≤2 months and >2 months. The results indicated a negative correlation between serum iron levels and the duration of hair loss, suggesting that iron deficiency was associated with longer durations of hair loss in patients.
