Supersonic Hair Dryer，High Speed hair dryer, blow dryer or straightener is an electrically mechanical Smart device which rapidly 

blows hot or ambient air over wet hair to dry it quickly. 

Blow dryers allow greater control over the structure and form of hair, by regulating and manipulating the generation of temporary 

molecular bonds in each hair strand. The hair is exposed to a blow dryer for a specific period of time - typically from half a 

second to four seconds. This period is termed the heat pulse. Prior to the heat pulse, the hair is wet with water and is either 

slightly damp or completely dry.

A hair dryer works by breaking a hair shaft into short, even strips called "pieces" by subjecting them to high voltage positive ions. 

An electrical current is then passed through the pieces, causing them to vibrate. The vibration generates heat which warms up 

the hair above the average rate of drying human hair.

Due to variable wattage, there are three classifications of hair dryer - conventional ionic and negative ions. Most models fall into 

the conventional category. 

Conventional hair dryers utilize an electrical current that passes through a heating element, generating direct heat to the hair 

shafts. The negative ions in ionic dryers provide a much different thermal treatment than traditional tangential ones. Negative 

ions not only provide a more defined curl, they also prevent frizzing and static.

A third type of hair dryer which is growing in popularity is the diffuser. A diffuser is designed to enhance the natural curling of curly 

or wavy hair textures. Most professional stylists utilize a diffuser in their hands while working on a client's hair for maximum results. 

With a diffuser, the natural curl of the curls is maintained for a longer period of time. This is because the diffuser directs the heat 

down to the ends where it most effectively melts and raises the curl. With the help of a professional stylist and a quality diffuser, 

you can achieve the same results that you would from a conventional hair dryer.

There are two types of hair dryer that are commonly used today - the Portable blow dryers and the electric blow dryers. 

Portable blow dryers are compact and lightweight, which makes it easier to use. These types of blow dryers are able to generate 

more heat for more precise heating of the hair shafts.

Electric blow dryers Currently there are areas of the market ordinary hairdryer and high-speed hairdryer, the general line length of 

3m or so, high-speed hairdryer advantage is the use of BLDC high-speed brushless motor, part of the high-speed hairdryer 

products will come with a self-cleaning or 200 million anionic features

Most professional stylists recommend the use of all of the above tools in your styling arsenal. In addition, you should invest in a 

quality hair dryer that can handle the extreme nature of your hair type. Once you have found a Supersonic hair dryer that suits
