Why do moles grow such long hairs?

Some moles grow hairs much longer than the surrounding area, why?

They're called terminal hairs and we don't really know why they grow longer than normal hairs. They do appear to be influenced by hormones during puberty; so it could be that the mole hair follicle has a slightly different base level of receptors, or interacts differently with the bodies normal hormone levels.
