Why do some hairs on your body grow differently? For example, the hair on your head and face can keep growing but your eye brows will stop at a certain point, if you were to shave it. Also, why are pubes coarse?

All the hair on your body has a life cycle. It grows, falls out , lays dormant a little while then grows again. That is why people lose hair every day but don’t go bald. It is also why you have hairs of different lengths all the time. The hair on your head, your eyebrows and the hair on your arms are all programed to grow for different lengths of time before they fall out.
