Shiny science. What’s the science behind hair shine? It’s all about light reflection. If hair is exposed to extreme heat, strands can become difficult to align and raise the protective cuticle layer to scatter light in all directions – making hair look dull. That’s why the Dyson SupersonicTM hair dryer is engineered with intelligent heat control, to regulate temperatures.
