Gray hair can revert to its natural color and the secret to it

We who dye our hair know this. Month after month, the roots grow out, causing the hair to lose its color. As the years go by, the problem is that the hair color begins to turn ashy. In some cases, even white. What most people do is to dye their hair again. Science offers a less aggressive alternative for the scalp that has little to do with dyes and peroxide.

A root problem

The origin of gray hairs is in cells in the head that produce certain colorations depending on information at the genus level. However, when they stop producing them, the hair turns grayish and white.

For this reason, according to Michael Eidelman, medical director of Chelsea Skin and Laser in New York, there are people who have them at earlier stages than average.

According to an expert-led study, "on average, 50% of the population will have half of their hair gray by age 50," says Eidelman. However, this effect is spontaneously reversible - at least temporarily. However, the root of the problem must be addressed.

A recent study from the University of Miami shows that across different ethnicities and genders, the trigger for gray hair is stress over and over again.

It is not just the hair color that is affected. On the contrary, various tissues in the body and behavioral patterns are altered during prolonged periods of stress and pressure.

The study's research team realized that the hair condition reveals a lot about the physical condition of the entire organism. As the hair ages, the rest of the body is likely to do the same. For this reason, the solution may lie in locating the points that irritate people the most.

The lead author of the study, Ralf Paus, suggests that possible treatment may be more effective when the first gray hairs appear.

The link between aging and psychological stress was fundamental to find an early solution. Because many people lose their hair color when they have to cope with difficult life situations.

As a result, Paus emphasizes that much of people's medical and biological history can be seen in their hair. Gray hair can show signs of more stress in life: It's pretty clear that hair in some ways encodes part of your biological history," explains.

"Hair grows out of the body and then crystallizes into this hard and stable [structure] that preserves the memory of your past."
