A hair blower (also known as a hair dryer, hairdryer, or blower) is an electromechanical device that blows hot air over damp hair to speed the evaporation of water and shape or style the hair. It works by creating a high-velocity blade of air that’s engineered to be focused so you can style one section at a time.
The motor inside the hair dryer creates a current of electricity that makes a small fan spin. As the fan spins, it pulls air from outside and pushes it over a heating element. The hot air is then forced out the end of the barrel by forced convection. The current from the motor also swaps the polarity of the magnets in the rotating shaft, which creates a magnetic field that keeps the spinning shaft pointing in the same direction and away from the heater.
Depending on your hair type, you’ll need to select the best heat settings. “Those with thin or flat hair should opt for a low heat setting to avoid overheating the delicate strands,” says Wizemann. Those with coarse or thick hair can choose a higher heat setting to reduce drying time and help shape the hair with less damage.
Many professional hair dryers also have ionic technology that generates negative ions to help reduce static electricity. This results in less frizz, smoother and healthier-looking hair that’s easier to tame. hair blower
