Why does the fur of animals stop growing/shed past a certain length but we have to manually cut our own hairs?

Answer 1

You don’t have to cut your hair, you cut it for cosmetic appearance. There is a “critical mass” for you hair length and it is different for everyone. So unless you are taking especially good care of your hair, you will notice at some point it will affectively just stall in growth length. And either fallout normally or break off.
