got2b glued freeze spray is the most wig-compatible hairspray you can buy! I'd also steer away from hairgels, they're supposed to react to the natural oils in human hair, which doesn't have the same result on wigs! (I know this question wasn't for me, I'd love to hear Weisel's suggestion too! (=⌒▽⌒=) )
And thank you so much!
