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?

Eyebrow hair has a different string of proteins in its DNA coding for its design, meaning when they form they are constructed differently.

Like the blueprints for them contain different instructions.
