ELI5: Why is hair growing out of moles thicker than other hair?

I have three moles that seems to act like fertilizer to my hairgrowth. This "superhair" is similar to beard, as it is thicker and stronger than normal hair, and grows annoyingly fast.

Moles are basically a tumor. The unusual cell cluster pushes on the follicle, making it grow hair faster than usual. They're darker because of the extra melanin in the area from the mole. It's actually a good thing if your mole grows hair because that's a sign it's not cancerous.
