Another way of getting rid of the curls is with a straightener WRAPPED IN TWO OR THREE PAPER TOWELS OR MORE IF IT'S REALLY HOT. Everyone says to never straighten a wig, but as long as the straightener is wrapped to death, and you don't touch the hair to the metal EVER, it works. We've straightened two wigs and even crimped two with the papertowel method, and the only time hair melted was when we held it there for an entire minute cuz we stopped paying attention. XD So don't do that. Also, don't touch the hair until it's completely cool as it is just semi-melted plastic at that point. >>
On the hair being too short thing, if you pull A LITTLE from farther back (but not enough to show netting) like lurkingpuppy said, it should be enough to make it work. Good luck! ^^
