short hair

I know a girl at school who has shoulder length, thick hair. She sometimes puts it in hot rollers and then pulls the sides back and secures them with small hair bands or clips. She also does a curly style by putting hair gel in her wet hair,but I am not sure how exactly she does that. Most of the time because she dances,she puts her hair in a ponytail and then folds it under,not completly pulling the hair through the hair band, forming a loop type bun.
