POSSIBLE ETIOPATHOGENESIS OF GRAYING Reversible hypopigmentation of the hair can be seen in nutritional deficiencies protein-energy malnutrition and diseases of chronic loss of protein. Copper and iron deficiency also can cause graying of hair.

A review of research suggests that proper supplementation may reverse premature graying in those who are deficient in certain nutrients, including iron, vitamin D, and vitamin B12. However, even though some supplements are specifically sold as “anti-graying,” there aren't any studies that prove they work.
In most cases, once hair has turned grey or white, it cannot naturally return to its original color. This is because the melanocytes in the hair follicles stop producing melanin. While there are exceptions due to specific factors, regaining natural hair color without external intervention is rare.

The average age of onset of hair graying appears to be mid- to late forties; however, this varies with race, with the average age for Caucasians being mid-thirties, that for Asians being late thirties, and that for Africans being mid-forties.
So, if you notice black hair roots, it's because your melanocytes have been producing melanin normally. Interestingly, melanin production can restart after a period of dormancy, which can lead to a strand of hair that's white or gray on the tip and black closer to the root.
