Hair falling out! Literally!

Lauren
This is the hair I lost tonight in the shower! This happens almost every time I shower. I brush my hair throughout the day and lose hair too; more than what would be considered a "normal amount". I have gone to the doctor and she said my anemia could be a cause of it and told me to take b-12 to help. Nothing seems to be helping! I'm starting to get concerned. I don't have any bald spots but the amount of hair I lose in the shower makes me cry every time 😭 does anyone else have this problem?!
