A hair dryer or straightener is an electrical device that blows dry or ambient air onto wet hair, rapidly 

accelerating the evaporation of oils and drying the hair quickly.

Hair dryers allow for greater control over the structure and texture of the hair by quickly controlling and 

accelerating the creation of temporary molecular bonds within each strand. These bonds strengthen the     

hair shaft and provide better elasticity. The speed, intensity and duration of hair dryer use can also have a 

direct impact on the strength of the hair shaft, which is why many professional stylists advise their clients 

to use a hair dryer on specific days of the week or for each hair type.

There are three main categories of hair dryers on the market. Traditional regular hair dryers; 

newer combination ionic hair dryers; and 200 million negative ion high-speed brushless hair dryers, also 

known as supersonic hair dryers.

Traditional hair dryers use static electricity between the charge collector and the motor. Newer combina-

tion ion hair dryers utilize negatively charged ions to absorb moisture. Finally, the most efficient and co-

mmonly used is the supersonic hair dryer (high speed hair dryer) a device that combines the features of 

all three types of hair dryers with a self-cleaning feature.

In addition to providing hair styling and blow-drying capabilities, advances in hair dryer technology have 

made these devices quieter than previous models.

The latest generation of hair dryers are less likely to produce annoying "whirring" noises. In addition, some 

of the newer hair dryers feature safety technology such as auto shut-off, one-touch cold air, and thermostat 

protection.

The auto shut-off feature stops the unit from running at the end of the styling/blow-dry cycle. This reduces 

the risk of hair dryer burns and overheating and extends the overall life of the unit.

A common question about hair dryers is how they work:

Basically, the hair dryer is powered by accessing the power supply to the hair dryer's control board, 

which acts as the core part controlling the operation of the motor. 110,000rpm high-speed brushless 

motors are commonly used in the market today, and the motor rotates to drive a fan that transfers heat 

from the heat source to the hair and scalp. The hot air of the hair dryer is conducted through the heat 

wire, and the fan drives the transfer of heat to the hair dryer outlet. At the same time, the hair dryer with 

negative ions is able to eliminate most of the static electricity that may be generated during the styling 

process.

As far as safety features are concerned, the only safety factor that needs to be taken into account is that 

ordinary hair dryers should never be placed on cold surfaces. Otherwise, the electrical components may 

overheat and begin to smoke.

To test this, place the hair dryer on a countertop before turning it on. If the hair dryer begins to smoke, 

return it to the shelf.

Also, don't leave a regular hair dryer plugged in for more than five minutes at a time. This can lead to 

overheating and electrocution.

In addition to not being particularly safe, regular hair dryers have some disadvantages.

For example, regular hair dryers can be quite heavy, especially if they are made of metal. They tend 

to produce a lot of fumes, so they may not be as portable as hair dryers made from other materials.
