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.
So, if your parents experienced greying early in their lives, you might too. However, it is not possible to restore your hair's colour, unlike what most claims on the internet might tell you. Your hair follicles cannot produce melanin on their own.
Although this may seem like a permanent change, new research reveals that the graying process can be undone—at least temporarily. Hints that gray hairs could spontaneously regain color have existed as isolated case studies within the scientific literature for decades.
Graying reversal won't work for everyone
If strands are about to go gray anyway — perhaps near middle age — a stressful event might push hair cells past that threshold earlier, the study noted. Then when the stress ends and the hair is just above the threshold, it could revert back to dark.
Vitamin B-12 is the most common culprit, with folate, copper, and iron deficiencies increasing your risk, too. Dietary supplements may help these deficiencies and you might see your natural hair color start to grow back after several weeks.
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.
Vitamins B6 and B12 have also been proven to boost melanin production. Goddard says that vitamin B6, also known as pyridoxine, has been found to trigger the production of enzymes and chemical reactions that boost the metabolism of the hair proteins (keratin and melanin) in the hair follicles.
Since baking soda is a scrubbing agent, washing your hair with it can gradually strip the dye from your locks. Baking soda can lighten all hair colors, but it might take a few washes to get your hair to the desired color.
It turns out that, among people who are nutrient deficient, supplementing with vitamin B-5, high-dose para-aminobenzoic acid, iron, or vitamin B-12 might help reverse gray hair.
Usually, our hair will turn darker because eumelanin production increases as we age (until we go gray, that is).
Gray hair poses some unique challenges. It's coarser than your natural hair, and gray hair follicles make less oil, making it drier as well. This makes it harder for color to penetrate, so you may have to leave it on longer, which can cause more damage.
Your hair doesn't turn gray — it grows that way.
A single hair grows for one to three years, then you shed it — and grow a new one. As you age, your new hairs are more likely to be white. "Every time the hair regenerates, you have to re-form these pigment-forming cells, and they wear out," says Oro.
Vitamin B-6 and B-12 are two of the Complex-B vitamins that aid in healthy skin and hair. B-6 may help restore hair to its original color following an illness or deficiency. Para-Amino benzoic Acid (PABA) and Pantothenic Acid are part of the family of B-complex vitamins.
Foods to increase melanin in the hair
Copper-rich foods such as various kinds of nuts, mushrooms and meat liver also promote follicular melanin synthesis. Sources of vitamin A, C, and E including carrots, papaya, eggs, citrus fruits, sunflower seeds, almonds, peanuts and pistachios can improve the health of your hair.
Redken Color Extend Graydiant Purple Shampoo
As its name suggests, Redken's Color Extend Graydient Purple Shampoo was made specifically for gray hair types. This anti-yellow shampoo balances undertones with the help of its purple pigment.
Purple shampoo has been used for decades by hairdressers, mostly to help tone and neutralize blonde and gray hair, getting rid of brassy or yellow tones for an overall more cool-toned look.
Although the primary cause of premature hair graying (PHG) is considered to be genetic, certain environmental factors also play a role. Trace element deficiencies such as Vitamin B12, Vitamin D3, and calcium may also be associated with PHG.
Scientists don't know exactly why some people go gray early, but genes play a large role. Also, a vitamin B-12 deficiency or problems with your pituitary or thyroid gland can cause premature graying that's reversible if the problem is corrected, Benabio says.
“Plucking a gray hair will only get you a new gray hair in its place because there is only one hair that is able to grow per follicle. Your surrounding hairs will not turn white until their own follicles' pigment cells die.”
Aside from the time investment of a salon session, there's how long it takes to fully transition to gray hair, which is anywhere from six months to a year, Ferrara says.
