I asked the same question a few months back in the Biology section. It is because the follicles of the hair on your arms and legs have a shorter age than the ones on your head. So when your leg's and arm's hair reaches a certain age, they fall out. That's why they never get to be so long.
Why do the hairs on your legs and arms remain at the same length and your facial hairs keep getting longer?
GRAVITY LOL
Why do the hairs on your legs and arms remain at the same length and your facial hairs keep getting longer?
It's what the cells are programed to do.
All cells start as the same thing, but somewhere along the line of development, they only switch on certain genes and those genes tell the cell what it will be, what it will do.
hair follicles on your head grow while the arms and legs only grow a little.
Why do the hairs on your legs and arms remain at the same length and your facial hairs keep getting longer?
they actually do but since you rub your arms and legs a lot on clothes and etc. it stubs the growth.
Why do the hairs on your legs and arms remain at the same length and your facial hairs keep getting longer?
This has to do with genetics. There's something in your genes that codes for your body hair to grow to be a certain length while the hair on your head keeps growing. Although for some people even the hair on their head, once it reaches a certain length, either stops or slows down significantly.
