i had those several years ago. my doctor at the time called them wins. she said they were a small tumor like under skin on my head. she removed them in the doctor office small incision popped them out and tied my hair together with string instead of stitches. i would'nt pop them out myself should let the doctor do it for sure. hope this helps.
i have bumps on my head that act like zits but are harder to pop. there is a hard white piece that comes out. what is it. so these bumps that are on my head are hard to pop but if i keep messing with them they eventually pop there are hard white pieces that come out. sometimes they act like zits and the whitish puss stuff comes out like any other zit. but anyways the hard white piece comes out and i had thought they were calcium deposits. the last one that i had popped a small round hard piece came out that looked like an onion. that it had layers of "skin" and was probably mush on the inside. what is it?
