I'm not a teen, but maybe this would help a little. Since my hair is still short and I like to wear buns and stuff I like playing around by adding braiding hair in with my hair for thickness or to make buns and usually come out with some cute styles. I'll attach some pics of some of mine and also others that I've found on the net that are pretty easy to do. With faux buns you can pretty much go crazy and get really creative because all you have to do is pull your hair back then pin the fake hair in whatever style you like then you can add cute accessories like flowers, peals or chopsticks and tadaaaa!!
