serum, to lock in moisture and to keep bangs straight,
and holding spay, to keep the curls.
just blow dry it with some serum already in your hair, and then, when its dry and such, add just a little more and brush it, then use a sorta medium curling iron, and after each curl, spritz it with a little spray. then when youre done, tousel them a little, and you should be set!
thats basically what I did when I had extensions, but since I didnt have any serum, I just used sheen spray. but sheen spray will only make your hair greasy looking, so dont use that!
hope that helped! :]
