You need a new cable that will slot into the end of the straighteners, all cables should come with a plug fitted at the other end, and Ebay have sellers on there under the catagory GHD Hair Straighteners for around £5.99..This happens to all straighteners eventually, even those from the GHD site, hope this answer was helpful to you...:-)
