Well my hair is pretty straight. I certainly wouldn’t consider it curly at all, but i seriously just brush it and let it air dry and it has some wave to it, similar to Emma. Clearly they use a curling iron on Emma’s hair a bit and create some of those ringlets, but the thought that her hairstyle would take any time never even occurred to me because i am almost there and i do nothing. It probably does depend on what your hair is like though like you said.
