Blow-dry bars are all the rage in certain cities right now, but there's nothing more convenient than being able to create looks in the privacy of your own home. Still, it's not always an easy thing to do on your own head. Luckily, heat tools (blow dryers, curling irons, flat irons, etc.,) have come a long way from the appliances of yore. There are blow dryers boasting the same motors used in your garden-variety male midlife crisis convertible (seriously, the Ferrari dryer exists). There are curling irons, wave-makers and flat irons that can turn even the frizziest, unruly hair into spun silk, no matter which hair care and styling products are used. And in the last few months in particular, there have been many technological advances in the hair heat tool space.
