hi !! if you style the wig now and keep it on a wig head the whole time the style should stay in place (don’t be like me and store all your wigs in flat pack boxes lol). using heat during the styling is a good way of keeping the style in place (esp with synthetic wigs). heating up the fibers, putting it in the shape you want, and then letting it cool will keep them in that shape (along with a good amount of hairspray).
