Which is better, a hollow hair dryer or a traditional hair dryer?

1, faster dry hair speed: hollow hair dryer design can accelerate the air flow, making the wind speed and wind pressure more powerful, so as to blow more hot air in the same time, so that the hair more quickly dry, while the traditional hair dryer drying slow.

2, lighter hand experience: the hollow design makes the whole hair dryer more lightweight, more comfortable in hand, and easier to use for a long time, while the traditional hair dryer is bulky and inconvenient to hold in hand.
