Move over, Chewbacca, cause Jessica Alba now has the best hair in Hollywood. According to what I can only assume is the most scientifically-accurate poll ever conducted in modern times, Jessica Alba has the most desirable hair of any actress right now. Despite Jessica Simpson's hair once being the envy of all women, Alba managed to beat out her and others. Alba's locks represent a more laid back, lower maintance kind of style. So do mine, but no one seems to care about that.
