A hair dryer, blow dryer or flat iron is an electrical device that blows hot or ambient air over wet hair to dry it. Flat irons are used to dry long hair, while hair dryers help speed up the drying time of short hair. Blow dryers also help in creating a smoother look to the hair and reduce the amount of frizzing and static electricity caused by brushes, rollers or flyaways. By accelerating and regulating the generation of temporary hair bonds inside each hair strand, blow dryers help in shaping and defining the form and texture of hair.
Blow dryers have two major components namely: the hair dryer itself, and the heating element. The main components are designed such that they operate efficiently under constant voltage control. Moreover, the outer case is made of heavy duty plastic so that the motor does not get overheated. The heat dissipating from the plastic cases is also optimized by utilizing the latest thermodynamic technologies. Another benefit of using a plastic outer case is that they are very durable and can also handle humidity and salt spray well.
The electrical motors inside a blow dryer are usually housed within a metal or plastic casing. One advantage of metal casing is that they heat up fast and attain high wattage output. On the other hand, the plastic casing is lightweight and is therefore cheaper. Also, the plastic casings tend to be more easily molded into different shapes, thereby allowing designers to add various features.
One of the most innovative and popular features present in hair dryer today is its ability to produce cool shots. Some blow dryers even have a variable setting that allows users to set the required wattage to produce different cool shots. These cool shot techniques enable users to get professional results and at the same time save lots of electricity. For instance, a low wattage blow dryer will produce a cool dry effect that does not require a lot of energy but still preserves moisture. Meanwhile, if the required wattage is set at a higher level, it will produce a warm air dry effect that is very helpful in making the hair look shiny.
There are several types of hair dryer available in the market. Some blow dryers have been designed for professional use, while some others are designed to be used at home. A hairdryer with an integrated gas stove is highly recommended for professional use because it consumes lesser amount of electricity compared to an air dryer and will consume lesser gas too. Additionally, a gas stove hairdryer consumes lesser time and effort than an air dryer. The only disadvantage of a gas stove hairdryer is that it does not produce any steam.
If you are looking for the best hair dryer then it is advisable to go through all the options so that you know which one suits your needs and budget the best. In general, there are three types of dryers namely, rotary, electric and combination. All the three dryers can be used for different purposes but the rotary ones are best suited for frizzy hair. Electric dryers work on the principle of heating air and then blowing it through the hair shaft and preventing premature drying. Combination dryers are the best option for those who want to have both immediate and also long lasting effects.
