It may have to do with your irregular periods. You said that you always have them most of the time right? I wish you all the best luck. You don't want to your pretty hair to get thin. Hopefully it won't be a biggie and you'll be all well in no time! Good luck!

Aaah! Don't think of such things silly! It won't be anything bad hopefully! If its just a little minor hormone related thing, its very curable and isn't even a disease. Just the way some people are. Don't worry!!!!!
