I know you said it wasnt medical but before I got pregnant, I was losing my hair in bunches. It ended up that my iron levels were extrememly low even though I was taking a multi vitamin with iron. My endocrinologist put me on iron pills and that really seemed to help. So far, even after having my daughter, my hair isnt falling out again like before. Im hoping the problem is solved but I become so paranoid even at seeing the slightest few hairs.
Stress is a major factor with hair loss and it could be inherited as well from her family. I wore my hair back in barrettes and ponytail holders all of the time too. He told me that this could cause stress on the roots of my hair, causing some loss but it shouldnt be a reaccuring thing. He also told me to leave my hair down for a while to allow it to relax from the tension.
Im glad to hear that her hair is growing back. Losing your hair for now apparent reason can cause a great amt. of stress on top of everything.
I hope everything works out for her. Keep us up to date on this. I hope to hear that everything is ok real soon!
Give her an extra hug from me
