Hairspray
It seems like the hairspray was a huge element throughout the movie which I think was hilarious. Can anyone tell by the scene that Uma got Juliette a new hairspray in the supermarket what brand of hairspray it was?
Also, I think both Uma's and Juliette's heavy eye make-up in the movie were very beautiful. I'm really into this kind of stuffs so I tend to notice these things a lot.
And by the way, I feel like both of them were set to be very self-conscious girls who're very keen on make-up and hair. You can tell by little things they did in several scenes.
