Hi,
I ordered a replacement lead from ebay but it wasn't the correct one so i had to "butcher" it to make it work and even now its tempermental. The choice is yours, its an iffy fix but it i guess its ok as a stop gap and is electrically sound (as in no risk of shock).
Look up hair straightener cables or power leads and it should only cost you around £5-8.
Hope this helps
