I am a 53 year old white male. I have a couple of greyish bumps on my head. They are small like a pimple, domed shaped and do not hurt nor itch. Two are on my left temple just inside the hairline and one is on my forehead at the hairline. I am asking your opinion prior to seeing a dermatologist, to see if at my age these are common on the scalp. When they formed, I believe they were red bumps which stung and itched for a few days as they formed, then turned kinda greyish. Now they have no itching or stinging when touched.
