These researchers found no significant difference in folate and vitamin B12 levels between patients with hair loss and control patients [35].
As a result, when vitamin B12 levels are low, your hair follicles may not be able to grow new hair efficiently. This will result in hair loss. B12 deficiency can also lead to symptoms of anemia, which is linked with low iron levels, hair thinning, and hair loss.

Although a deficiency in B12 may lead to hair loss, research does not suggest that people who do not have a deficiency can improve their hair growth by using a supplement. Nevertheless, getting enough vitamin B12 is essential for overall health. Good sources of vitamin B12 include meat, dairy, and other animal foods.
One of those vital nutrients is B12, also known as cobalamin. B12 promotes healthy hair growth by assisting in the production of oxygen-rich red blood cells, which feed hair follicles.
Only riboflavin, biotin, folate, and vitamin B12 deficiencies have been associated with hair loss.

Animal products such as meat, dairy and eggs are the only sources of B12 in humans, and the recommended daily allowance is 2.4 micrograms per day.
Even the lowest doses in B12 supplements are many times the recommended dietary allowance. Doses up to 1,000 mcg, though unnecessary, aren't harmful.
Significantly exceeding this dose, however, can cause illness. In general, the symptoms of vitamin toxicity include nausea, gastrointestinal problems like constipation and diarrhea, hair loss, rashes, and nerve damage.

B vitamins have not been linked to cause hair loss, however when reversed there are studies that show that a lack of or deficiency in B vitamins can cause significant hair loss.
