Where abouts do you keep your hair straightener? As it may be because its cold or has condensation inside it. This may sound funny but you actually shouldnt keep your GHD in the bathroom cause they can get cold and dont like it, or if u want to keep it in the bathroom then wrap it in a towel. This may fix the problem. If not then call GHD and you may be able to get a replacement. Hope this helps :)
In 2001, ghd revolutionized the way women styled their hair with the launch of its first styler - a professional tool designed for salon use that could also be easily used at home. ghd continues to be one of the leader and innovator in hair styling with its range of professional brushes, hair straighteners and hair dryers, and ghd Style styling products.
The ghd platinum+® styler gives you the perfect finish using ultra-zone with predictive technology that maintains a safer-for-hair heat from root to tip, reducing hair breakage* and increasing shine by 20%**. So now your hair can be stylish and healthy – all in one stroke. Alternatively, select the ghd max styler, which is the perfect straightener for long hair. With its cooler, lighter body and smoother plates it will glide through your hair to give you a salon finish every time.
To have straight hair, you just mist your hair with the GHD thermal protector. You then start at the part of the hair that’s closest to the roots, and then you glide the GHD Classic 1-inch Styler to the tips in one smooth stroke. You can also follow the easy directions for soft movement and for curls, which involve some turning while you glide from root to end. 
* * * Update: After returning the above-described item, I bought a ghd Classic Styler in-person from one of their authorized salon dealers (info at ghd's site). When I went to register the hologram and date codes, the ghd site accepted them on the first try. Also, the second unit I bought HAD country-of-manufacture information on the box and on the date sticker (made in China, which some other comments said isn't legit, that seems to be wrong). My unit labeled made-in-China is the one that registered successfully with ghd. Also my second purchase - from the authorized dealer - had a lot of information printed on the bottom of the box, including a bar code, web info, consumer information phone number, design info and information about the product. The unit I purchased from Amazon had NO printing on the bottom of the otherwise authentic-looking box. Draw your own conclusions. Bottom-line: if you buy a ghd styler here, double and triple-check that your unit is for real.
For me, the first and still very best of all ceramic stylers [and my dad is a hairdresser too]. It heats up fast, cools down relatively fast, works wonderfully and lasts a long time. In 11 years, I've bought two such stylers. The first one eventually died after 6 years of daily use, rarely skipping a day, while my second one is still going strong. I have no reason to recommend any other styler but this one. My hair is long and very fine.
