Contact GHD asap. That's how I knew something was off with my straightener. The first time it happened the same thing to me, I turned it off, removed from the plug and waited and tried to turn it on again but I still get the red light flashing on and off. I tried doing it for a few times but still had the same issue so I contacted GHD and they replaced my straightener but after a few months it happened again. It sucks because for the price we pay for these straighteners we expect quality but unfortunately it isn't the case with these products.
This is an expensive straightener, but it's worth every penny! I've had mine now for over a year, and I know I'll have it for many years to come. The iron itself is black and gold. I have long, thick, straight hair, but it gets a little wavy underneath if I let it air dry. If I blow dry it, it gets a little poofy and I use this to give it a more smooth, sleek look. It takes a couple passes of going over my hair before it's completely straight, but with cheaper ones it takes longer. It doesn't take too long to do all of my hair. It heats up super fast, and if I'm in a hurry and forget to turn it off, it turns off by itself after thirty minutes. I have dropped it a few times, and it's still going strong. I recommend this for everyone.
Over a decade on from revolutionising hairstyling with the launch of its first styler, ghd remains true to its founding ethos: the spirit of transformation. Ghd have since broadened their super range from stylers to professional quality brushes and the most impressive hairdryers available on the market today. Even after all these years the Ghd hair straightener is still very much a must have for most women and men who want smooth, sleek luscious hair - especially with us girls from Millies. 
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.
