This week we've seen two more celebrities take to the bottle. Xtra Factor presenter Caroline Flack left her trademark dip-dye behind to go fully blonde, tweeting a picture of her new look with the caption: "Hey girlies... My dip has died...block blonde!". Across the pond, Elisabeth Moss did the double by debuting both a new bleach colour and a crop style at Tuesday's New York premiere of For A Good Time, Call.... This follows Miley Cyrus' headline-grabbing dye and crop the week before, and X Factor judge Tulisa Contostavlos' statement-making bleach reveal outside court the month before. Which new blonde's hairdo do you like best?
