Is it true that long & short hair are based on genetics?

I thought that EVERYONE could grow long hair. I didn't know that there was a long hair gene %26amp; a short hair gene. My tutor told me that in high school.

That might explain why some people's hair grows faster than others.

Is it true that long %26amp; short hair are based on genetics?

My understanding is that hair will grow for a certain period of time, and at a certain rate, before that strand of hair falls out and is replaced. Both the growth rate and longevity of the hair is genetically determined. Therefore, some people will be able to grow their hair very long, while some others will not. The hair simply falls out before it reaches that length.

Is it true that long %26amp; short hair are based on genetics?

Human hair has an indeterminate growth. It will grow unless you stop it. We don't have short haired people. We do have short haired dogs. Most animals that have fur have a determined length. It grows to a point, then it is shed or exchanged for another coat of fur. Same goes for feathers, grows to a certain point, stops, is shed, regrows.

wow you run into uninformed people

It's true, some peoples hair grows faster than others. Mine for example grows almost twice as fast as an average person's hair. Some people have hair that grows slowly.

Also, some people have brittle hair. It breaks off at a certain WEIGHT. It's not that it's impossiable to grow your hair. It's that your hair will break. hair is constantly growing and if it didn't break off, anyone could grow their hair like rapunzle(sorry, bad simmile)

So it's not genetics that makes your hair short or something like that. It's how strong it is.
