Strange as it may sound, most of us are especially fond of this change. we lived in childhood and adolescence and did not doubt much. However, science has a logical answer to the situation, which is very difficult to understand.

Now from the hair colors we had as kids, how it can later turn into a completely different color let’s see.

Our hair and eye colors are mostly shaped by our genes, but this choice of color is related not only to the genes we have, but also to their change depending on a few factors.

Our hair color is actually formed by the amount of a natural pigment called melanin in our hair. melanin pigment, formed by cells called melanocytes and these cells remain active in every strand of hair.

This melanin pigment is divided into two different types, eumelanin and pheomelanin, both of which impart a different color to the hair. Eumelanin gives the hair a brown and black color And the more this pigment is in the body, the darker the hair will be.

Pheomelanin, on the other hand, regulates the redness of the hair, just as eumelanin regulates the darkness of the hair color. also pheomelanin pigment, The more there is in the hair, the more the red tint will increase. In addition, if the amount of pheomelanin in the body is much higher than it should be, the color it gives to the hair can become completely invisible.

Each of us has the genes to produce these two types of pigment, but the cells in our body do not produce them in equal amounts.

At this point it is decisive that genes play a role in open and closed forms. For example, the melanin genes in the soles of the feet and palms are turned off and inactive. Over time, however, these genes can turn off when they’re on and on when they’re off Along with different parts of our body, our hair can also change color.

When it comes to color change, hormones play a major role in addition to genes. Hormones are a type of chemical signals responsible for sending messages between parts of the body and Changes in hormone levels cause pigment genes to turn on and off.

Although these hair color changes, which are caused by genes and hormones, are mainly seen in children and young people, they can also affect adults from time to time. Again, diet, age factor and the amount of sun exposure cause changes in the types and amounts of hormones produced by our body. In short, this change It can happen to you at an unexpected time in your life.

So what causes hair to turn white or gray as it ages?

As we age, the cells that produce melanin in the body don’t work as well as they used to and they wear out. Worn-out cells cannot properly transfer the pigment to the hair and hair Hair that gets a small amount of pigment turns gray and hair that doesn’t get pigment turns white.

In short, if these cells die at a young age, new ones will take their place, but due to advanced age, the cells cannot be renewed. So a If the melanin is not replaced, the hair in that area will remain unpigmented. and the hair that tends to turn white or gray remains in this way.
