Return youth: scientists have discovered a way to restore the previous color of gray hair
With age, many often develop gray hair. Of course, people want to hinder the natural process of the human body, which, as it were, signals the approaching old age. And for this there are means designed to prevent such a process. Yes, some of them promise to get rid of gray hair. But there are those that can return the hair to its natural color. Is this possible, the publication found out Huff Post.
Even L'Oreal took up the topic by announcing in 2011 that it would release an all-natural pill that would prevent gray hair within five years. But after a while, a spokesman for L'Oreal said that this is no longer a priority area of their research and innovation group.
But as this abandoned project hints, the reality is, preventing and reversing gray hair is not as easy as taking a pill - at least not yet.
The mechanisms behind hair coloring are complex, as the appearance of gray hair is caused by the loss of pigment. As we age, we produce less of it, which leads to gray hair. When exactly this happens is genetically determined.
But there are several reasons why gray hair can grow ahead of time. Craig Ziering, a board-certified dermatologist and founder of Ziering Medical, says a deficiency in vitamins, especially B6, B12, D, E, or biotin, can accelerate the growth of gray hair.
Oxidative stress, caused by both internal factors (such as unhealthy diets) and the environment (such as UV radiation), can very well make a difference. Smoking also has a significant impact: "Studies have shown that smokers are twice as likely to go gray before age 30 than nonsmokers," Ziering said.
Even hair products, including those used to color or bleach hair, can contain ingredients that reduce the level of melanin in hair.
“Hydrogen peroxide, which is found in many hair dyes, is one such harmful chemical. Excessive use of products that discolor hair will eventually lead to graying too, ”warned the dermatologist.
Stress is also a very significant factor - remember the often-cited comparison of the presidents of their first and last year in office.
Keeping your hair free from silvery is big business: take a look at the range of products available that claim to act as a remedy for gray hair. But, according to experts, it is impossible to restore hair to its previous color or prevent age-related pigment loss.
“Certain nutritional deficiencies and health conditions can cause premature graying, but natural hair color cannot be restored if it is hereditary or caused by natural aging,” says Ziering.
However, you shouldn't lose hope if you want to minimize the amount of gray hair. Even based on what we know about their nature (that is, if the hair turns gray, there is no turning back), one study showed that reducing stress can help in this matter. The researchers found that some of the subjects had previously gray hair repigmented after the subjects went on vacation. The study has its limitations, but it demonstrates that stress, like stress reduction, can actually affect hair color.
“We cannot completely rid our hair of gray hair,” said Martin Picard, Columbia University researcher and author of the study on the topic. “However, this observation shows that aging is malleable is not a fixed, predetermined process. Our behavior and perhaps our perception of the world, as well as our stress levels, affect how soon our cells age and when our hair eventually turns gray. ”

In addition to reducing stress, there are other methods that can help minimize the development of new grays, but only if the cause is lifestyle or lack of nutrition.
“Certain vitamins and minerals help ensure that your hair follicles have maximum nutritional value for metabolic functions in the follicle, one of which is the production of pigments the hair needs to maintain its natural color,” explained Ziering. "The amino acids and proteins that trigger metabolic functions in our follicles are beneficial."
“Eat right, sleep well, combat environmental factors and avoid smoking,” he advises. - Use sun protection for hair and scalp. Increase your intake of calcium, protein and B vitamins. ”
For those supplements that claim to prevent gray hair, they can technically work by replenishing nutrient deficiencies, but no more than eating a healthy diet or taking a multivitamin.
Therapies are currently being tested and shown to reverse graying and hair repigmentation. “These agents include enzymes like catalase, which breaks down hydrogen peroxide, which is known to accumulate in the dermis of graying hair,” explained Craig Ziering. "In the future, this may someday become the mainstay of treatment that reverses the depletion of the pigment potential of melanocytes in hair follicles."
“Not today or tomorrow, but in the near future, we can potentially find a treatment that will lead to the restoration of richer and more youthful hair color,” - said the founder of Ziering Medical.
A Columbia University researcher also continues to study the nature of gray hair. “I think we will learn more about the effect of the mind on the body. About how our human experience is anchored in our biology - in our hair, - Picard shared his thoughts. "Mind and body are connected, and you can see it even in the hair."
