As we get older, the pigment cells in our hair follicles gradually die. When there are fewer pigment cells in a hair follicle, that strand of hair will no longer contain as much melanin and will become a more transparent color — like gray, silver, or white — as it grows.
Although white hair is characteristic of aging, colorless hair strands can appear at any age — even while you're still in high school or college. If you're a teenager or in your 20s, you might find one or more strands of white hair. There could be ways to restore pigmentation, but it depends on the cause.
A strand of hair can appear gray when it contains a decreased amount of a pigment called melanin, and it can look white if there is no pigment at all. Gray hair occurs with normal aging because the hair cells on the scalp produce less melanin; in children, early graying tends to be inherited.
Vitamin A, C and B12 are the most needed vitamins to increase the melanin production in your hair. Add citrus fruits like oranges, grapes, pineapple, and melon to your diet. Also eat vegetables like potatoes, carrots, beans, etc. Non vegetarians can try adding red meat, chicken liver, fish, and eggs to their diet.
Despite the claims made online and by product marketers, it's not possible to reverse white hair if the cause is genetic. Once your hair follicles lose melanin, they can't produce it on their own. As melanin production slows, your hair turns gray, and then white when melanin production has completely stopped.
Kraleti doesn't recommend plucking or pulling the hairs out. “If there is a gray hair you must get rid of, very carefully cut it off. Plucking can traumatize the hair follicle, and repeated trauma to any follicle can cause infection, scar formation or possibly lead to bald patches.”
In humans, most gray hair is not related to stress. In fact, hair doesn't actually "turn" gray at all. Once a hair follicle produces hair, the color is set. If a single strand of hair starts out brown (or red or black or blond), it is never going to change its color (unless you color your hair).
Can White Hair Turn Black Again? Genetic or age related greying of hair cannot be reversed. However, greying related to diet, pollution, bleaching and stress can be slowed down with a balanced diet and a good hair care regimen. Know your hair to figure out hair care that suits your hair.
Even teenagers and people in their 20s may notice strands of white hair. The human body has millions of hair follicles or small sacs lining the skin. The follicles generate hair and color or pigment cells that contain melanin. Over time, hair follicles lose pigment cells, resulting in white hair color.

The team ultimately discovered that signaling from the sympathetic nervous system plays a critical role in stress-induced graying. Sympathetic nerves extend into each hair follicle and release noradrenaline in response to stress. Normally, the melanocyte stem cells in the follicle are dormant until a new hair is grown.
