However, as of now, there is no widely accepted scientific method to restore the natural hair color once it has turned gray or white. So, while you can manage white or gray hair through various treatments and dyes, turning it back to its original color naturally is currently not feasible.
Grey hair that is caused by aging, thanks to old age, cannot naturally turn black again. But grey hair that originates from discoloration, stress, nutrition, pollution, vitamin deficiency and other physical ailments can be turned black again naturally if cared for properly.
Black tea is a natural dye that will make hair darker. Black tea works best with prematurely grey hair, and is simple to make--you only need two ingredients. You can leave the tea in for up to two hours, or you can leave it in for less time and apply it more frequently.
Unfortunately, there is no single vitamin or supplement that can directly turn white or gray hair back to its original black (or other) color. The graying of hair is a complex process that involves a gradual decrease in melanin production, the pigment responsible for hair color.
No impact on gray hair: There is no scientific evidence to suggest that baking soda can prevent or reverse gray hair. The color of our hair is determined by the presence of melanin, a pigment inside the hair fiber.
Apple cider vinegar not only lightens hair color to diminish brassy tones but also acts as a natural cleanser, removing product buildup and hard water residues. You can make an apple cider vinegar hair rinse for gray hair at home. Mix one tablespoon of apple cider vinegar with one cup of water.
Hydrogen peroxide is a natural oxidant; we produce an enzyme called catalase that breaks down hydrogen peroxide turning it into water and oxygen. As catalase function decreases, the levels of hydrogen peroxide increase. High levels of hydrogen peroxide block the production of pigment, leading to gray hair.
Unfortunately, there is no scientific evidence to suggest that increasing vitamin B12 intake can reverse existing gray hair. Hair that has already lost its pigment is unlikely to regain its natural color.
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.
Several natural methods, particularly those that reduce stress, may help you to naturally reverse premature grey hair. These include exercise, mindfulness practices, healthy sleep habits, and building a supportive social network. A balanced diet may also help if your grey hair was caused by nutrient deficiencies.

Rubbing onion juice onto the scalp helps in the reversal of grey hair. The tannic acid present in the black tea helps in darkening the hair color.
We have previously published findings that, after the age of 50, humans are seldom with- out gray hair. At this age, around 50% of men and 30% of women are moderately or totally gray haired.
As we age, melanocytes decrease in number and less melanin is produced. Fewer melanocytes mean a lack of pigment in the hair, resulting in a silvery-gray color. Now the hair itself is not actually white; it is an optical illusion that results when light is refracted off the hair, creating a silver-like look.
It has long been thought that reversal of gray hair on a large scale is rare. However, a recent study reported that individual gray hair darkening is a common phenomenon, suggesting the possibility of large-scale reversal of gray hair.
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.

A good source of B12, such as an apple, banana, blueberry, or eggs, should be added to improve B12 levels over time. However, for short term improvements in your levels you should start with medication.
This is why baking soda (sodium bicarbonate) has been incorporated into beauty routines due to its alkalinity with a high pH level. The substance works by lightening gray hair but should only ever be used cautiously as it also affects moisture retention capacity making it brittle.
While no definitive scientific evidence shows that Ashwagandha can completely reverse gray hair, it may help slow down the graying process.
Carbamide peroxide is a common form of hydrogen peroxide ear drops. These drops release oxygen in the earwax, causing it to bubble. The addition of oxygen softens the plug, making it easier to remove. In general, hydrogen peroxide has a good safety profile if used properly.
