ELI5: Mole Hairs

ELI5: This is gross but how come a hair that grows out of a mole is longer than any other hair in the nearby vicinity?

A mole is a small cluster of specialised skin cells called melanocytes.   Usually, melanocytes are spread out evenly, but now and again they clump together and form a mole.   A melanocyte’s job is to produce melanin, which is the pigment or colour in your skin.  This is why moles are dark, and also why you can get moles by being in the sun.

Hairs that grow from a mole are affected by this melanin just like skin is.   Melanin makes hair darker and coarser, and longer.   The structure of these “mole hairs” is more like the hair on your head (or pubis) than the hair on your arms or legs.
