For creating glass-straight styles or simply smoothing flyaways and texture, this flatiron from legendary hairstylist Harry Josh really delivers. The floating ceramic plates heat to 425 degrees Fahrenheit, and the iron is smart-battery-powered (the battery lasts for up to 50 minutes of styling, which is game-changing for a cordless tool). The streamlined shape is also brilliantly easy to handle, plus its universal voltage (100–240V) is ideal for international travel. To recharge the battery, use the accompanying USB cord—or try Josh’s ingenious charging base (sold separately).
