TLDR Low iron, low thyroid function, and stress are linked to excessive hair shedding in women.
In 2016, a study was conducted on 100 premenopausal women aged 18-50 years suffering from chronic telogen effluvium (CTE), a disorder characterized by excessive hair shedding. The study found that 66% of the patients had significantly low hemoglobin levels, 76% had low serum ferritin, and 24% had hypothyroidism. Among the women with low hemoglobin levels, 72.7% had significant stress levels and 60.4% were working women. Ten patients had significantly low serum ferritin levels of less than 40 μg/L, despite having normal hemoglobin levels. Nine patients had both low serum ferritin and low thyroid levels, and eight patients had lower than normal levels of all three markers. The study concluded that there was a strong association between anemic conditions and CTE, and that stress also played a significant role in hair loss in women.
