This would be a very close fight between two hot and evenly matched young women. Given their professions and the fact that they both wear their hair very long, I believe they would focus on trying to pull as much of each other's hair out of their scalps as possible -- particularly since its a black vs blonde tresses competition. The winner would be the one who could endure the pain of having her hair yanked and torn longer than her opponent. I think Sophie, the hairdresser, would have the edge over Tina, the fashion designer, because hair is Sophie's business and she probably knows how best to give Tina a new "do" with just the use of her bare hands.
