Quick tip for BIG curls! use rollers! it's better that using a curling iron because you won't burn your hair and don't even need to blow dry it before you roll ir =) just spray some fixer and hair lotion when it's still wet and roll your hair ! leave it all night and take the rolls off the morning! there you have your big hair!
I like to use a flat iron when it's really too big on the front side bangs !
