only mine are lot more than that. i want to put rollers in them and have them curly but if i do that then how do i heat it up? i can't BLOW DRY, cus that won't work. i can't STEAM IT cus that won't work so the only thing i can do is like dip my head in a bucket of hot water so the curls will hold. i need to put curlers in it like this:
