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 :)
GHD Classic Styler, from the name itself, you can deduce that this simple yet versatile device was made to style and straighten. Armed with a rounded barrel and advanced ceramic heaters, you can curl, flip, tease, wave, and straighten any hair type and texture easily without damaging your hair’s external surface. The infra-red heat technology infused within the plates also releases more negative ions than other products so your hair’s natural oils and luster are retained despite repeated exposure to maximum heat.
