Imagine lugging this portable around with you? but if you travel back in hair dryer time far enough, you'll find large bonnet styles on tall stands that could slide, fold, roll and do whatever it took to be... portable. The very first hairdryers were completely stationary and scary. I don't know who invented the portable but hair dryer academics say the first hair dryer was invented by some French guy hair stylist back in the late 1800's. I think that hair dryers simply became portable by degrees, each one smaller and easy to tote around.
