i had it done (cant remember what they used) but it didnt work. apparantly it was my hair type. its not even that curly really. my SIL has nicole kidman type curls and it worked for her. she loved it, and yes she was able to put it up etc (like you mentioned). it did look a bit wierd as the roots grew back they were curly. you have to keep getting it done or use your hair straightener to do roots after a while.

that seems pretty pricey. i think i paid under 200 when i got mine done(about 4 years ago though). i asked my new hairdresser and she said it would be about 190.
