By Many people know the daily practice of washing, drying, and styling hair. Even though hair will eventually dry on its own if given enough opportunity, the vast majority reach for a hair dryer to speed up the interaction. While science may have disproved the connection between wet heads and twitching bugs, it’s still no fun lounging around with a full head of wet hair, especially in the coldest time of year.
Hair dryers, also called hairdryers, were first sold during the 1920s. At first, they were very risky to use: many people were shocked when they dropped their hair dryer into water-filled sinks and bathrooms.
How hair dryers work Full guide
That’s not as possible today, however, due to the advent of ground fault circuit interrupters (GFCIs). Starting around 1991, US government regulation has expected all compact hair dryers to protect you against electric shock if you were advised to inadvertently drop one into water while it’s plugged in [source: CSPC]. This applies whether the hair dryer is on or off. A GFCI is the largest and most captive plug you will find on many customer appliances. When connected, GFCIs analyze how much flow is running from one split outlet opening through an electrical circuit and back to the next area. If they detect an interruption in the current, they trip the circuit. (See How Does a GFCI Outlet Work? for niceties.)
What happens to a hair dryer if you drop it in water when it’s not plugged in? You don’t risk getting an electric shock, since there is no source of flow, but you can damage the hair dryer if every part gets wet. In this way, related or not, it is an ill-conceived idea to throw it in the tub.
Have you ever thought about what those parts are inside a hair dryer that allows you to blow hot air through your hair without consuming your scalp? Keep checking to find out why it doesn’t sizzle.

You can find a hair dryer like this at virtually any drug or bargain store. Essential models have two switches, one to turn them on and off and one to control the rate of the wind current. Some models have an additional switch that also allows you to control the temperature of the wind current.
The hair dryer evaporates the hair by accelerating the dissipation of water from the hair’s surface. The hot air that comes out of a hair dryer increases the temperature of the air that surrounds each strand of hair. Since hot air can hold more moisture than room temperature air, more water can be moved from your very high hair. The rise in temperature also makes it easier for the individual particles in a drop of water to cancel out on each other and go from a fluid to a gaseous state.
Since they were first developed, many different hair dryer models have been licensed, but most of them only change the outer packaging of the dryer to make it look more attractive to you. Aside from the expansion of some security features, the operating system inside hair dryers hasn’t changed much over time.
A hair dryer needs only two sections to produce the impact of hot air that dries your hair:
a basic motor-driven fan
a heating component
Hair dryers use the motor-driven fan and heating component to convert electrical energy into heat by convection. The whole instrument is really simple:
The moment you plug in the hair dryer and turn on the switch, the current courses go through the hair dryer.
The circuit first supplies capacity to the heating component. On most hair dryers, this is an exposed curly wire, but on more expensive models there may be fancier real-life materials, like an art cover implanted with tourmaline.
The flow then, at that point, turns the small electric motor, which turns the fan.
The wind current produced by the fan is coordinated down the barrel of the hair dryer, over and through the lime component
