The programming actually happens at conception, long before birth.
Some hairs are programmed with "keep growing indefinitely", like those on our head. Some others are programmed to grow to a certain short length, like those on your arms.
It's specified in your DNA.

The length, perhaps not, but the rate at which it grows is programmed into your DNA. People always ask what they can do to help it grow more quickly. You can't! But you can take vitamins and take measures to keep your hair and body healthy to ensure it grows at the quickest rate and doesn't break off.

Hair will grow indefinately, there is no set length. However, the rate at which it grows is controlled by your DNA.
