I am 28 years old and have picked scabs on my scalp since I was about 12 years old. Normally I find little imperfections, possibly dandruff
or dry scalp, and I pick at it until it becomes a scab. Once a scab develops, I find myself uncontrollably picking at it, so it usually never heals or takes an extremely long time or another scab to develop to stop. Right now, I have a total of six scabs that I have created on my scalp.
