The plates are made of aluminium which is used because it has powerful heat conducting properties – four times better than steel. The aluminium is coated with a thin layer of an advanced ceramic coating, which helps the plates glide smoothly through the hair and leaves hair looking shiny. The combination of the excellent heat properties of aluminium and the smoothing properties of the thin ceramic coating gives you the great styling results you expect from ghd. You may notice a slight gap between the plates - do not worry as this is a design feature that allows for thermal expansion to take place. All of our stylers heat up to the optimum styling temperature of 185ºC - a safer for hair heat.
