A blow dryer is a device used to dry hair. It also helps to shape and coach hair into a specific direction or style. While any heat styling can damage your hair if used incorrectly, properly blow drying your hair should leave it healthy and vibrant.

The most basic blow dryer consists of a motor that creates an electric current, which is then used to power the fan, and a heating element. The motor is a small electric machine that provides motive power by spinning a coiled wire of nichrome (a type of resistor). When the blow dryer is turned on, the nichrome wire heats up and generates an electrical current that powers the fan, creating a stream of hot air.

Blow dryers usually have an on/off switch and a heat setting switch. They may also have a fan speed switch to control the flow of air. Some blow dryers have a concentrator nozzle attachment to focus the flow of hot air for easier styling and control.

When blow drying your hair, the best way to get a great look is to work in sections. This will ensure that all strands are properly dried, and will help to prevent the cuticles from becoming lifted and rough. It will also make it easier to maneuver the brush or comb, and will save time because you won’t have to go over the same areas more than once. The number of sections will depend on your hair length and thickness, but about 5-6 should work for most people. blow dryer
