All three of these B vitamins are essential to the normal formation of hemoglobin, which carries oxygen from the lungs to tissues in the body, including the hair.
Healthy and strong hair relies on a constant supply of blood and oxygen. A deficiency of these B vitamins is like cutting off the blood supply to your hair, leading to increased hair loss, damaged hair and slow re-growth.
