What Are These Things??? (photos Are Included)

[Blackbird307]

My scalp is incredibly itchy and I'm losing hair as I scratch it at an alarming rate. I tried washing my hair more frequently and less frequently, using different shampoos with no change in problem. It's been very bad for the last 4 months. My entire scalp itches!
