Forget hair extensions, not only are they time-consuming, high-maintenance and expensive, they're so three years ago! This year, it's all about the wig. But we're not talking about your regular plain and safe wig, no. Take Lily Allen, for example, who has become queen of the wig this summer – changing wigs mid-festival performance depending on her mood (pink, blonde and purple at Glastonbury). Then, on a night out with new BFF Kate Moss, Lily took inspiration from her partying partner by wearing a platinum blonde number. It's not just Lily whose been enjoying a wig-athon, Lady Gaga (would you expect any less) and Britney Spears, who has been familiar with the advantages of the wig ever since that hair-shaving incident, have regularly been chopping and changing 'their' hair. So are wigs the new hair extension? Absolutely.
