In short, I regard the two conditions as separate and unrelated.
Acne itself does not affect the
scalp. In my experience, many cases of
scalp folliculitis are stress-related. Unless a culture actually shows staph germs, I would be skeptical that these bacteria are playing any role here. If a topical antibiotic doesn't help, perhaps a topical steroid might. Ask your dermatologist. Also, be sure never to scratch any of the spots, since that perpetuates the problem.
Take care.
