* [[Vitamin B12]]. Since a deficiency in this can cause premature gray hair, make sure you’re getting enough. If you do not eat animal products, it is important that you supplement this vitamin or eat foods that have been fortified with it.
* Raw food diet. Many proponents of raw foodism have claimed that their gray hair began to reverse back to its original color after they adopted a raw diet.
* magnesium contributes to normal protein synthesis. This is a process in your body that produces proteins. If you consider that your hair is almost entirely made up of protein (keratin), you can imagine that normal protein synthesis is important for the growth of your hair. Better protein synthesis means healthier hair and a more predictable hair cycle. Just like many processes in the body, think of your period, your hair also has a certain cycle. In the hair cycle, phases of growth and rest alternate. Protein synthesis also helps your body produce [[melanin]], a substance that prevents your hair from turning gray.
* Copper-rich foods. Researchers have found that people who go gray prematurely have lower copper levels than those who don’t. So stock up on copper-rich foods like leafy greens, nuts, beans, bananas, avocadoes, and grapes.
* [[Wheat Grass]] juice has been shown to turn gray hair back to its natural color : According to Traditional Chinese Medicine, hair pigmentation is influenced by the quality of blood and the strength of the kidneys. If your hair has gone gray, your kidneys and blood need to be strengthened. Foods that accomplish this include wheatgrass and any food with high chlorophyll content.
