Pimple on back of my head, an inch in back of my ear?

Every time I get my hair cut I get a pimple on the back of my head, I saw one on my friends head once. I dont know why it is always there. Is it a irritation from the razor or whatPimple on back of my head, an inch in back of my ear?
irritation. clogged hair folicals. nothing to be worried about. ALL MEN get them when they shave or get hair cuts. if you dont get them then you pretty ain't much of a man.
It may be due an irritation, but it's natural to get pimples on the head / scalp. Our hair follicles have sebaceous (oil) glands underneath. No need to worry about it, as long as they're not all over your head.
