Hey, so my hair has fallen out twice, first time just a little bit, I could hide it, second time it was a lot I shaved my head. now im growing it out its about 3 inches long.. and well im either being paranoid or its falling out again... if I run my fingers through the bottom back of my head, or the sides, I get hair, but none on the top and top back... so I was wondering how it happen with other people.. its a lot that comes out... anyones opinions on if its paranoia or if its happening…
