The Buffy and Angel Trivia Guide // Wiggins

Sarah Michelle Gellar seems to have been wearing a wig in the scenes prior to, and including, cutting her hair in Gone. This suggests that she had her hair cut before shooting of this episode began. It’s unlikely that she would have cut her own hair on film as it would be too risky in case she messed up and had to reshoot the scene. Sarah also doesn’t seem like the type of girl who would cut her own hair.
