TLDR People with chronic hair loss may have a higher chance of Vitamin B12 deficiency.
Between January 2015 and April 2018, a study was conducted involving 317 patients with Chronic Telogen Effluvium (CTE), a common cause of hair loss, and 327 healthy individuals. The average Vitamin B12 levels were statistically similar in both groups. However, Vitamin B12 deficiency was found in 38 (11.98%) of the patients and in 22 (6.72%) of the controls, a statistically significant difference. The study concluded that there might be a correlation between CTE and Vitamin B12 levels, as the deficiency rate was significantly higher in the patient group.
