2. Vitamin B12
Next in the line of vitamins for hair growth is Vitamin B12; another member of the B-complex league. Deficiency of Vitamin B12 slows down the hair growth. The reason for this is the B-group vitamins are needed to supply the different cells of the body with the required nourishment. In the absence of B12, the hair follicles are undernourished. B12 deficiency may also cause the hair to fall out. The dietary sources of Vitamin B12 are meat, fish, eggs and diary products.
