I have a problem with my hair. It seems that lately I’ve been getting these strange bumps on my head that seem to be pimples only on a very different scale. They are quite rough and I can tell that there is a dense liquid behind them. Out of curiousity I’ve popped them and they usually scab and go away. But about a day or two after they go away, they leave a baldspot, usually the size of nickel or dime. Sometimes the spot is bald for more than a month and sometimes only a few weeks. I’m afraid to cut my hair because I know they will be clearly visible. What do you think this is?
It sounds like you have recurrent folliculitis. See a good dermatologist and get it treated. Infections can produce temporary balding around the infection itself.
