In a series of videos, Boomerangs, and photos on her IG Stories, Munn wrote, "My hair is so thick and heavy so i have a hard time getting body into it. Sooo I'm putting in my first permanent wave with @bykileyfitz" — followed by a play-by-play of the entire process. (Shrieks of pain and all.) Fitzgerald started by wrapping Munn's hair in a set of long, orange curlers, then applied the formula, towel blotted, and rinsed. Track the timestamps from start to finish, and you'll see she was at the salon for a good one to two hours. (Good thing she was doing lots of leg kicks to keep the blood pumping.)
