The number of heating modes provided in the tool.
The presence of several temperature modes makes it possible to choose the best option for a particular situation. For example, for quick curling of "naughty" hair, when speed is more important than delicacy, you can set a strong heat, and if there are no problems over time, you can use a lower temperature. But the specific amount directly depends on the type of device (see "Device").
So, in hair dryers of one kind or another, there are usually few temperature modes — up to 3 in household models, and up to 8 – 9 (occasionally more) in professional ones. But curling irons and stylers, even relatively simple ones, can have several dozen levels of adjustment — their operating range is quite wide (for example, 130 – 200 °C), and the temperature in this range is often adjusted in steps of several degrees.
Also note that in hair dryers
, temperature control and
power control are carried out separately, and these parameters can have a different number of settings (for example, 2 power levels and 6 temperature levels). In curling irons, stylers, etc. the temperature only changes at the same time as the power, so the number of power modes may not be indicated at all — it corresponds to the number of temperature settings by definition.
The length of the cord for connecting to the network, provided in the design of the tool.
The long cord provides greater freedom of movement, which is particularly beneficial in hairdressing salons and beauty establishments where professionals need to move around their clients. However, for regular household use, excessive cord length can lead to inconvenience, as it may get underfoot or cause other issues. A cord length of 1 – 1.5 meters is generally sufficient for home use. On the other hand, for professional tasks, tools with a cord length of 1.8 meters or more are commonly available.
