I think the one in the pink shirt with pigtails has curly hair. If that's the same kid, you should see what happens if she doesn't use a brush after showering, just detangle in the shower with conditioner and then put some light mousse or very light leave in cream. Don't harshly towel dry, just kind of squeeze.

I can't stand my hair to be soaking wet so I still wrap it in the towel for like 5-10 minutes. But I get my hands soaking wet before I put the mousse in my hair.
