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.
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.
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.
One of the most frequent causes of premature hair greying is a vitamin B-12 deficiency. Researchers have found that in persons whose hair has already begun to grey early, vitamin B-12 shortages frequently coexist with folic acid and biotin deficiencies.
You can take a supplement that contains these vitamins or you can supercharge your diet with foods high in B12 and B6. Eating beetroot, sprouts, eggs, fish, cheese, soy and starchy vegetables are healthy ways you can increase melanin in your hair.
The most popular solution is changing the hair shade with tea or coffee. A good replacement for chemically-packed products is also a natural hair dye, meaning - henna. However, you must use it skillfully so that the shade you get is natural and not too ginger (unless that's the result you expect).
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.
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.
The Colors to Avoid with Gray Hair
Here are a few to steer clear of: Muddy Neutrals: Beige, taupe, and other muted tones can make your skin look washed out and ashy. Earthy Yellows and Oranges: These warm tones clash with the coolness of gray hair and can make your complexion look sallow.
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.
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.
There's no hard-and-fast rule about when (or if!) you should stop coloring your hair and go gray; it's ultimately a personal choice.
Melanin is what gives your hair (and skin) its natural color. People of African descent, Thai, and Chinese people, go grey more slowly.
Premature graying may be reversed with vitamin B12 supplementation only if vitamin B12 deficiency is the cause. If you are graying due to other factors, such as genetics, zinc deficiency, and medications, your gray hair cannot be reversed.
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 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.
If the cause of greying is genetic, it is not possible to reverse the process, no matter what some marketers on the internet claim. In case of nutritional deficiencies and underlying medical conditions, you can gradually slow down or even reverse the process.
When used at regular intervals, coffee can prevent graying of hair. As it has pigmentation, it stains the hair when you apply it. Coffee turns the grey-colored hair into a dark color.
Coconut oil and amla powder
Amla aka Indian gooseberry can darken premature grey hair along with reducing itching and dandruff issues. Blending coconut oil would prevent the loss of protein or keratin from hair and would thus strengthen the strands.
