Ever found yourself pining for a plug point in a festival tent or searching for a spare adaptor on holiday? The Babyliss 9000 (£250) is a full-sized cordless, chargeable straightener and, unlike most wireless products we’ve seen in the past, it really works. When I tried it, it heated up in seconds and the ‘floating’ ceramic plates glided across my hair, leaving it with a silky, glossy sheen. Not cheap, but totally worth it. Hanna Ibraheem, beauty writer
