So what's the secret?...Tourmaline. Tourmaline is a precious stone that possesses unique ionic and infrared properties. The presence of Tourmaline mineral guarantees unsurpassed performance to make the H2D MK4 Wide Tourmaline Iron totally unique. The secret is the use of this very expensive, natural emitter of negative ions and infrared heat.

Working like a magnet, Tourmaline is the strongest, longest lasting source of infrared and negative ion emission and will make straighteners perform like no other. They are 4 times more effective than ordinary ceramic straighteners.

Negative ions close the cuticle layer to create a smooth, silky hair surface and seal in the hairs natural moisture. This provides ultimate shine, colour and moisture protection and also eliminates static electricity on the hair surface so your hair is left silky and frizz-free.
