Have you watched someone try to hide gray hair by dyeing it or using Reparex? Or maybe you wonder why your grand uncle has a full head of silver hair while in old pictures it’s brownish. Getting gray, silver, or white hair is a natural part of getting older, and here’s why.
Each hair on the heads is made up of two parts:
a shaft – the colored part we see developing out of our scalps
a root – the bottom part, which keeps hair anchored under the scalp
The source of each and every strand of hair is enclosed by a tube of tissue under the skin which is known as the hair follicle (say: FAHL-ih-kul). Each hair follicle posesses a certain amount of pigment cells. These pigment cells constantly produce a chemical called melanin (say: MEL-uh-nin) that gives the growing shaft of hair its colour of brown, blonde, black, red, and anything in between.
Melanin is identical stuff that makes our skin’s color fair or darker. It also helps evaluate if a person will burn or tan in the sunshine. The dark or light shade of someone’s hair is dependent upon how much melanin each hair has.
As we get older, the pigment cells within our hair follicles gradually die. When there are fewer pigment cells in a hair follicle, that strand of hair will not contain as much melanin and definately will turn into a more transparent color – like gray, silver, or white – as it grows. As people continue to keep become older, fewer pigment cells are going to be around to make melanin. Eventually, the hair can look completely gray.
People can usually get gray hair at ages young and old. Some people go gray at a early age – as early as when in highschool or college – whereas others could possibly be inside their 30s or 40s before they notice that first gray hair. Despite the fact that we try to stop gray hairs but arrival dependant on our genes. This means that a lot of people will begin having gray hairs round the same age that our parents or grandparents first did.
Gray hair is more noticeable in people who have darker hair because it stands out, but people who have naturally lighter hair are merely as very likely to go gray. From the time an individual notices a couple of gray hairs, it could take much more than A decade for all of that person’s hair to turn gray.
Lots of people assume that a big shock or trauma can change a person’s hair white or gray overnight, but scientists don’t really feel that this occurs. In case, attempt not to freak out your parents too much. You won’t want to be blamed for any of the gray hairs!
