I went through a very detailed system of constructing my own "wig" for a puppet. I bought a wig that was not attached to a net for only $3 US, and then basically divided it into two layers of hair, duct tapes off the ends to hold them together, then stitched them tightly to a piece of fabric that was the same type of that used for the scalp. Then I cut a slit down the center of the head and inserted that scrap with the hair attached to it and stitched the scrap to the surrounding scalp fabric. It makes a nice part down the middle of the head, but I don't exactly know the look you're going for. I'm sure you could figure something out with an un-netted wig.
