How Hair Dryer Works

Electric hair dryers work by blowing room temperature air in through the vents. The air then passes over nichrome wire coils that heat it, making it able to blow the hair dry with hot air. The process of air blowing on the hair speeds up water evaporation.

WORKING OF HAIR DRYER

Personal hair dryers come in a variety of shapes and sizes, but they all contain the same components and work in the same way. The typical hair dryer includes an on/off switch, a fan-speed switch, a fan and motor, a heat switch, a heating element, and a thermal cutout switch.

The heating switch controls the amount of current delivered to the heating element, thus controlling the heat delivered by the hair dryer. The fan-speed switch controls the speed of the fan motor and fan, thus controlling the force of the air delivered by the hair dryer. The thermal cutout switch, a safety feature, shuts off the heating element if it gets too hot.

History of Hair Dryers

The first hair dryer came onto the scene in 1890. Because people actually used to dry their hair using a vacuum cleaner, French salon owner Alexander Godefroy fashioned the first known hair dryer by switching a vacuum cleaner hose from ‘intake’ to ‘exhaust,’ making warm air blew out of it instead of into it. Needless to say, the design, though pretty ingenious, was not widely accepted for its bulk and clumsiness. Later, the dryer is known as the ‘hair hood dryer,’ made of hard plastic, was a large, dome-shaped hood that would fit down over a person’s head as they sat under it. Hot air was blown out through the small openings around the inside of the dome in order to dry the hair evenly. These dryers were very popular in salons until recently when they were largely replaced, even in salons, by blow dryers. The hood-type dryers are still used, mostly in salons, for clients who are getting something more done to their hair, such as a permanent or color.

Principle


Normally, evaporation is controlled by relative humidity — the ratio of the amount of water the air holds to the amount it could hold. For example, if the relative humidity is 90%, that means that the air is holding 90% of its maximum volume of water. When air is heated, its relative humidity decreases. It still has the same amount of water, but it can hold more. The lower the relative humidity, the more easily water evaporates. Therefore, hot air will dry your hair faster, since the water in your hair will evaporate more quickly.

Types of Hair Dryer

The most popular types of hair dryers in use today are ionic, tourmaline, and ceramic.

1.Ionic Hair dryer

2.Tourmaline Hair dryer

Tourmaline hair dryer types are made from this precious stone, tourmaline. The stone actually generates a lot of negative ions at once. As with ionic hair dryers, these negative ions soften and smooth hair, reducing frizz and static. Tourmaline hair dryers also heat up quickly, significantly reducing the time it takes to dry and style hair.

3. Ceramic Hair dryer

Ceramic hair dryers are popular because they dry hair quickly, and that often means less hair damage. Stylists favor ceramic hair dryers for this reason. Ceramic hair dryers contain self-regulating heaters and motors that are constructed of ceramic coils. These coils emit infrared heat. Ceramic dryers are also popular because their ‘Nano’ technology is known to reduce bacteria formation.

Electric hair dryers, especially the portable, hand-held kind, have certainly revolutionized not just the beauty industry, but life in modern society as a whole. Though this may sound like an overstatement, the truth is that hair is a billion-dollar industry in the U.S. alone, and hair dryers are at the forefront of this market. Hair dryers have become one of the most utilized tools in industrialized history. As a Hollywood actress once put it, “Without my hair dryer, I’m nothing!”

Advantages of Using a Hair Dryer

  • Decreased Drying Time: Thick and long hair takes a long time to dry. Using Ionic hair dryer breaks down water particles, leading to faster water evaporation and thus cutting down the drying time by 50%.

  • Reduced Frizz: Frizzy hair is prone to static which is why ionic hair dryers are perfect. Ionic technology will release negative ions that neutralize the static charges, minimize frizz, tighten cuticles and create a smooth finish. Ionic hair dryers also reduce surface tension which prevents the hair from getting tangled.

Disadvantages of Using a Hair Dryer

For curly and thin hair types, 1400Watt motor is sufficient enough to the hair shafts thoroughly without causing any damage. However, for those with extremely thick or difficult to dry hair, a dryer with wattage of 1800 to 2000 is recommended.
