Girls, hi. Such a question: my daughter has milk-like bumps on her head (serous) appeared a month ago, I didn't touch them, today reached, smeared cream and removed, they come off easily, the child is not painful, but where the bumps hair sticks out normally? In other places everything is fine, there are no bumps and hair doesn't stick out. I think maybe because the bump covered the hair bulb, so now the hair comes out there, who does that?
