 [ Symptoms ] 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 [ Disease ] when you say head do you mean the glans of your penis if so they are fordyce spots and should be left alone i assure you they are totally normal and harmless but keeping the penis hygienic is key to avoiding other skin issues like chafing dryness rashes and odors so a daily cleaning regimen that includes soap and a penis health creme is recommended check out man1 man oil it is the best creme out there for sure hope this helps and good luck
