As odd as this may sound, it's a theory that I am sticking too. The results of the Williams sisters depends on how their weaves are looking during the tournament. I warned you, but I'm dead serious.
Anyways, Serena's hair was looking great in Melbourne this year. She decided to tame it in her matches with a pony tail, and then busted out those bangs during her pressers and at her photo shoot. It was clearly the key to her 12th major title. She won last year's Aussie Open and Wimbledon with her fierce 'fro. The French, though, was a sort of a messy, indie girl look. She lost in the quarters. Catchin' on?
Venus, on the other hand, decided to hide her hair under her visor the whole tournament. Her result? A quarterfinal loss. Watching her sister's match, though, Venus was sporting the above 'do, which was pretty flawless. Had she gone with a headband instead of a hat, and flaunted her hair, she prob would've won.
