I know this question has been asked a dozen times but I'm hoping for a fresh answer from any ladies from North America who managed to take a hair straightener to London and have it work. I have read about dual voltage hair straighteners but can anyone who has been recommend a model that they used? I don't have the option of just buying a cheap uk model as my hair won't straighten without a very high temp, at least 400 or so. And curly is not an option. I look awful without my hair straight, even hair dressers say so. So if anyone has used a dual temp hair straightener recently that worked in London I would love to hear from you!
