I have a mole that normally grew two hairs and recently, it stopped growing one of the hairs. Does shaving over the mole too often cause this? Is the follicle in a certain phase? Or can it be cancerous? The mole doesn’t seem to be changing size or color. Please help! I have no family history of skin cancer but as a family, we do have lots of moles, many are funky. The rest of my moles that grow hair continue to do so and they don’t appear to be changing.
