hello, about a month ago I had an area on my scalp that was tender. After some inspection, I notice a pimple like bump, without any puss center....just a red raised sore bump. After about 2 days it went away, and I was left with a dry patch, as if it was a pimple that healed. Well about 2 weeks ago, the same thing appeared on my scalp right above my left ear.....at my hairline.....about 4 pimples. Same feeling as the original one, and they felt and looked more like pimples this time around, but not as sore as the first one. In all cases, no actual puss pimple develops, but dries within 3 days. The only thing that I ve done differently, has been the lack of washing my hair. I usually washed my hair every 3 days, but that has changed to about every 5 days....for the last 3 months. I ve also notice in the past month, after washing my hair, I have dry itchy scalp....maybe due to the lack of washes.
