It happens when brushing, combing her wet hair, combing dry hair. She has always had minor amounts of hair shed in the shower, but it is now noticeably thicker in the tub and wall of the shower. She is very worried about it as you can imagine. She has no cold or infection that is obvvious to see, but the cause of this amount of hair loss is of great concern to this family. Any advice is helpful, thank you for your time.
