Hello,
I'm a 30 year olld male and I keeping getting itchy scalps and when I scratch it, some of the scratched scalp gets on my fingers and there you could see dried blood on the scalp pieces on my fingers like small red spots. I've heard some where that you could lose your hair from something like that, and I have been losing some of my hair over the years. I'm just worried that the hair lose is from that issue.
