I have 3 small, light brown colored moles on my arms. Each one grows 2-3 strands of thick, dark hair, so what I like to do is trim them down 1-2 times a month with scissors or an electric shaver because it looks rather gross. I've been doing this for maybe 4-5 years. The odd thing is, all of a sudden, one of these moles isn't growing any of the hair back. The other 2 moles have grown out the dark hairs as the usual, but one of the moles, the hairs are still cut down to the size of almost nothing when I cut like 1 month ago. Is this something I should worry about? Maybe get it checked out?
