I need information about hair straighteners and dual voltage (US to UK)?

I am visiting friends in London for my winter break and had been planning to buy an American hair straightener. However I am hesitant to do so because of travel and the fact that my parents live in continental Europe. I need to know if it is possible to buy a hair straightener that only needs an adapter and works successfully in either America %26amp; UK, America %26amp; Continental Europe or just UK %26amp; Continental Europe. All information appreciated esp. personal experience -- as someone who travels a lot I try to avoid the appliance question at all times because have heard too many horror stories (fuses blown, etc). Ideally, would buy straightener that works (WELL) in all 3 of these places with only an adapter. Thanks for your time!!I need information about hair straighteners and dual voltage (US to UK)?
The US and UK have different frequency and even with adapters things made in US burn out fairly quick in the UK..My hair dryer lasted 2 days in the UK..The power cord for my laptop would only last about a week..Lived in the UK for a year and ruined lots of US stuff
