She was born with tons of it, and it's just kept growing! With minor cuts and trims along the way, it's been growing like a weed for her whole life. And she loves it. She likens herself to "Tangled", which is really Rapunzel, but she just calls her Tangled. However, she hates having her hair brushed, and with so much of it, it gets tangled, a lot. No pun intended:-) We were finally able to convince her to cut some of her hair off, reassuring her that no one would think she is a boy.
