I am a 25 year old, female, who is physically active and very healthy. I am not on and hormonal birth control.

Lately my hair has been falling out like crazy. I don’t have any bald spots or anything yet, but my hair is noticeably thinner. When I use to tie my hair back the hair tie would go around twice, not it goes around three times and is loose.

Soon I will start to develop bald spots. I don’t know what to do. My doctor isn’t too concerned because I still have hair and no bald spots. He thinks im freaking out about a few hairs at the bottom of the shower everyday, but it so much more than that.

Anybody know what would cause this is a young health woman?
