There's only 4 days left of the year and everyone is putting in their opinion on which things were most popular in 2009. Who knew the top trend in hair would be to have no hair--it seems like everyone was cutting off their hair this year. Remember a couple of years ago when Britney Spears shaved her head and everyone thought she was crazy? Well maybe she was just being fashion forward! Now two years later women are sporting short bobs, faux bobs, mohawks, buzz cuts, and the most popular, half shaved heads. Two people who really got this trend going were Rihanna and most definitely Cassie. Rihanna seems to be the queen of all haircuts (besides Victoria Beckham & Halle Berry) and Cassie really made herself more popular once she shaved her hair off! Take a look at some of the women who were brave enough to let go of their hair and made a big style statement.
