Nathalie and Samantha play a game of extreme shampoos. The goal is to destroy each other's hair with sticky messy foods that are hard to wash out. These girls get on great and just love being "playfully mean" to each other.

We allowed them to choose their own weapons. You can see what each girl chose in the video, but they include ketchup, Nutella and even, gulp, flour! There's lots of giggling and fun in the film, and the girls' hair looks amazing by the end.
