My 11 year old daughter started losing a lot of hair.... puberty related?

She is 11.5 and ive noticed her hair is like all over the place for the past 4-5 weeks.She is a deep thinker and worries a lot but says she hasn't been worried about anything lately. She is healthy.Could it be puberty related? via /r/Parenting https://ift.tt/2ztAyye
