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.
It's the same pigment that gives skin its color! This melanin pigment is made by special cells called melanocytes. These cells live at the bottom of each strand of hair. When these cells make a lot of melanin, your hair turns brown or black.
Your hair is mostly getting darker due to aging, medications, medical conditions, or environmental factors. Darkening strands may be natural or a sign that you need to seek medical or professional attention.
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.
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.
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.
A new study shows that stress really can give you gray hair. Researchers found that the body's fight-or-flight response plays a key role in turning hair gray. Your hair color is determined by pigment-producing cells called melanocytes.
For men having white hair was a sign of distinction, hinted at nobility, and was even a sign of virility. It couldn't have been more different for women. It was a sign of their deterioration with age, and the end of their fertility.
Harvard researchers have found that acute stress hyper-activates the sympathetic nervous system, which rapidly depletes the stem cells and leads to hair graying. (Image: Hsu Laboratory, Harvard University.)
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.
Environmental factors such as chlorine, sun and mineral deposits in water can also damage or discolor white hair. Wear a hat when spending long periods of time in the sun to protect hair from UV rays that can cause discoloration. Be sure to also rinse hair thoroughly after swimming in a pool or salt water.
And while it may seem intuitive that stress can accelerate graying, the researchers were surprised to discover that hair color can be restored when stress is eliminated, a finding that contrasts with a recent study in mice that suggested that stressed-induced gray hairs are permanent.
However, vitamin B12 may give you the appearance of fuller and thicker hair because the increase in oxygen to hair follicles can help stimulate the replacement of lost strands. Vitamin B12 may also help give your hair an overall healthier appearance since intake of enough B12 is responsible for stronger hair shafts.
As people get older, their hair often gets darker. According to IFLScience, this is due to changes in the production of melanin—the natural pigments responsible for hair, eye, and skin color. Two types of melanin are common: Eumelanin determines how dark your hair is, while pheomelanin controls how warm it is.
Usually, our hair will turn darker because eumelanin production increases as we age (until we go gray, that is).
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.
Marie Antoinette syndrome designates the condition in which scalp hair suddenly turns white. The name alludes to the unhappy Queen Marie Antoinette of France (1755-1793), whose hair allegedly turned white the night before her last walk to the guillotine during the French Revolution.
Jesus cautioned His followers, “Do not promise by your head. You are not able to make one hair white or black” (Matthew 5:36 NLV).
Does lack of sleep send my hair grey or white? Lack of sleep can have a negative effect on many aspects of the body, not only can it lead to tiredness and lack of concentration, but longer term effects such as your immune system and stress. Stress has been proven to cause grey hair as mentioned above.
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.
At a Glance. Stress can cause hair to gray prematurely by affecting the stem cells that are responsible for regenerating hair pigment. The findings give insights for future research into how stress affects stem cells and tissue regeneration.
Melanin deficiency is associated with vitamin deficiency. That's why you need to increase your vitamin intake through your food or vitamin supplements. Vitamin A, C and B12 are the most needed vitamins to increase the melanin production in your hair.
Low copper levels can lead to premature graying, according to one 2012 study. Good food sources of copper are beef liver, lentils, almonds, dark chocolate, and asparagus. These are superfoods for white hair, helping in its reversal.
Addressing deficiencies
Anyone who has white hair resulting from a vitamin deficiency should consume more foods loaded with those vitamins. For example, seafood, eggs, and meats are good sources of vitamin B-12, and milk, salmon, and cheese are excellent sources of vitamin D.
