Worn with pride by some and hidden by others,
gray hair is something as old as the very existence of human beings
and a sign of the passage of time. And although today there is a large stream of women who decide to stop dyeing their hair and show it as it is, since ancient times gray hair has never been highly regarded.
The Roman texts that have survived to this day talk about
how the women of Germany dyed them with the help of herbs
, or explain that the barbarians liked to dye their hair red.
But what we know today about gray hair is that some
simple habits can help slow down its appearance
, so if they start to appear and you want to take action without enslaving yourself to dye, I invite you to continue reading.
IS THERE AN AGE FOR ITS APPEARANCE?
There is no age as such at which the appearance of the first gray hair is considered normal, some people
already have a good part of their white hair
at the age of 30 and in others it does not happen until well
after 40
, and neither of the two cases represents a problem from a health point of view.

Science finds a formula to reverse the graying process
The appearance of gray hair depends largely on
each person's genetics and therefore responds to family patterns
: if your grandparents or parents had completely gray hair at 40, it is likely that the same thing will happen to you.
WHY DOES HAIR LOSE ITS COLOR?
It is a
natural process
related to
aging
that has a simple explanation. Each of our hair has a hair follicle, what is popularly known as the root, where in addition to other structures there are cells called
melanocytes
that are responsible for
producing melanin
to give the hair its characteristic color.
With the passage of time, and also due to another series of factors, these
melanocytes become less active
and begin to produce less melanin, giving way to the appearance of gray hair as the hair loses its pigment.
DOES STRESS ACCELERATE THE APPEARANCE OF GRAY GRAY?
It is popularly said that
stress or emotional tension causes gray hair
, and this is something that is supported by science. In 2020, a study from Harvard University managed to show that people who suffer high levels of stress in their daily lives are more likely to have gray hair.
This situation of tension maintained over time leads our body to
a pro-inflammatory state
that causes, among other things, the release of hydrogen peroxide and free radicals into our blood. This has as a direct consequence
a considerable decrease in the production of melanin
, and as we have already seen, if melanin falls, our hair color disappears.
THE RELATIONSHIP BETWEEN THE SUN AND GRAY GRAY
Another factor that can accelerate the appearance of gray hair is
oxidative stress
caused by exposing our hair to the
ultraviolet radiation emitted by the sun
for too long .
This explains why, as a study published in the journal
Nature
showed , citizens of
southern European countries are more likely to have gray hair at an earlier age
. Protecting our hair from the direct action of the sun could help delay its appearance.
DOES DIET INFLUENCE THE APPEARANCE OF GRAY GRAY?
That's how it is. That the lack of certain vitamins present in foods favors the appearance of gray hair is something that science has been able to demonstrate for just over four decades. If we have a
diet low in B vitamins, especially B12
, it is very likely that gray hair will appear
prematurely
.
If, on the other hand, we eat
a diet rich in vitamin C,
we can help
slow down the speed with which they appear
, and the catalase that comes from it will break down hydrogen peroxide, which, as we have already seen, is an element that promotes grayness.
