Grey hair naturally occurs as you begin to age. The hair is made up of two parts called a shaft and a root. As you get older, the pigments in the hair begin to die, leaving fewer pigments in the hair. When there are not enough pigments in the hair, a low amount of melanin will be present, turning the hair into different colors such as gray, silver or white, according to Kids Health.

Antioxidant Vitamins

Vitamins C & E both contains antioxidant properties that help to protect the body from free radicals, that can cause damages to your tissues, cells and organs, along with causing your hair to become unhealthy by turning it dry or thin. These substances form when the body has energy produced from the conversion of food to glucose. Vitamin C & E help to slow down the aging process, which is when gray hair occurs. Vitamin C can be found in citrus fruits and juices, while good sources of vitamin E include corn, nuts and sunflower seeds.

Vitamin B6

Vitamin B6 is also referred to as pyridoxine. It is part of the eight B vitamin group, according to the University of Maryland Medical Center. Vitamin B6 is essential for healthy hair and provides your hair with important nutrients that can help reduce the severity and chance of you experiencing gray hair. Like all B vitamins, it is water-soluble and all traces of it exit through urination. A low amount of this vitamin can be mildly deficient and cause weakness and short-term memory loss. Good sources of vitamin B6 include chicken and brown rice.

Folic Acid

Also known as vitamin B9, folic acid is essential for the body as it helps to keep the hair healthy and strong, according to the University of Maryland Medical Center. It is water-soluble like all B vitamins, so you need to have a continuous supply of it. Folic acid works with tissues to help them grow and enhances cellular function. According to MedlinePlus, a lack of folic acid can result in gray hair.
