Boyfriend Lost All His Hair on the Back of His Head

A few years ago my boyfriend got a hair cut and a month or so later he begin to get bumps which he assumed were razor bumps. shortly after he lost all the hair along the back of his head.

Now there’s no hair and bumps that at times bleed and cause him pain. What’s going on with his scalp?

This is difficult to answer, because it requires that I guess. One might assume that he got folliculitis from the shave and lost his hair. He needs to see a good doctor first and it should be clear what happened to him at the hands of a good dermatologist.
