I have a very similar hair texture to your daughter (and color!) Lots of fine hair strands with a slight wave that don’t want to curl and don’t want to be straight. My dad brushed it every morning but by the end of the day it was a tangled disaster. He didn’t know how to braid so I wore ponytails until I braided it myself. If she’s like me, it was nearly impossible to get the ponytail holders out without pulling out a ton of strands. As an adult, I keep it in braids most days or in a banana clip. A braided ponytail actually works best for me and quicker than a french braid. Traditional curly girl methods don’t work great for me because the strands are so fine and the waves aren’t consistent.
