I'm not very good at this, but here it goes. I'm 38 years old and thought I was in OK shape until my hair started falling out, not to much at first until I noticed a nice size bald spot on top of my head. I made a Dr. appt. they took blood tests and results came back that my white blood cell count was off. but everthing else was normal. could an infection cause my hair to fall out? I now have three more bald spots on the back of my head. My Dr. doesn't seem to be to concerned.
