The first thing that comes to mind when people talk about Dyson is usually the vacuum cleaner. However since the launch of their revolutionary cleaner they have also branched out into, hand dryers, temperature control and now hair. Can you believe that the technology in hairdryers has not changed for over 50 years? Well that is until now. Let me explain the £300 price tag. This is not a normal hairdryer. Where most hairdryers simply blow out hot air, which continues to get hotter, the Dyson Supersonic has a microprocessor in it which regulates the temperature so at its hottest, will not go above 100 degrees celsius. It blows out 41 litres of air per second, which by the sounds of it is enough to dry your hair very quickly. What's also interesting is the motor is not in the head like conventional hairdryers, it is actually in the handle and is five times faster than a Formula One car! Because the motor is in the handle, this makes holding it a lot more comfortable as the weight is balanced.
