Hmm, well the top girl (whose name eludes me right8 now
![XD XD](https://mlparena.com/Smileys/default/XD.gif)
) seems like she might have a little bit of tail rust inside, so if I were you my priority would be getting that cleaned out before it gets any worse.
As for Ringlets, I would start off with a nice warm wash, and leave in some conditioner in her hair overnight. Repeat that again and give it a good brush, and her hair should become much easier to handle ^_^
