At one moment when she feels rejected by her husband sexually she takes off her wig and tosses it into a trash can. Earlier in the play she makes a reference to just getting her hair done and looks in the mirror a couple of times so I don't understand why they need to show it was a wig, especially since her hair underneath was pretty similar to the wig in length and color. It didn't seem to add any emotional weight to the moment, in fact, it made me giggle to myself in a moment where I shouldn't be.
