Comparison Laifen Retro vs Laifen Swift

The type of electric motor installed in the hair dryer.

This parameter is specified if the device does not use a traditional collector (brush) direct current (DC) electric motor, but more advanced motor. The options here might be:

— AC motor. Hair dryers equipped with alternating current (AC) motors use the same type of power found in regular electrical outlets. These AC motors offer several key advantages over their DC counterparts, including enhanced reliability, durability, and excellent resistance to high loads. They can operate at full power for extended periods without overheating, often lasting for at least 5 years even under continuous use. Additionally, AC motors provide more even heating and facilitate quick adjustments to temperature settings. As a result, hair dryers with AC motors are essential tools in professional settings such as hairdressers and beauty salons. However, the main drawback of AC motors is their relatively higher cost, making them less practical for occasional home use.

— Brushless motor. A brushless electric motor, which eliminates the need for a traditional commutator and brush contacts, employs a built-in electronic circuit to control the current in the motor windings. Despite being more expensive than conventional brushed motors, they offer several advantages. These motors allow for more precise and wider range adjustments of engine speed an...d airflow, resulting in higher efficiency and better overall performance for the same power consumption. Moreover, the absence of moving brush components enhances their durability, leading to significantly longer service lives compared to both AC and traditional brushed motors. However, due to their higher cost, brushless models are not widely used even in the professional industry.

The rated power of the device, in fact, is the power consumed by it when operating at maximum intensity.

The power of a hair dryer, particularly for hair dryers, is a crucial factor that determines the maximum intensity of the airflow and heating capabilities. When selecting a hair dryer based on this parameter, it's essential to consider the intended usage of the device. Models with a power below 1000 W may not be sufficient for proper hair drying, especially for long hair, and are more suitable for styling purposes. Some of these models, particularly inexpensive ones, can provide high heat with low airflow, requiring careful use. For versatile and effective use, both at home and in professional settings, it's recommended to choose a hair dryer with at least 1800 W, preferably 2000 W and higher. Higher power allows for intense airflow, effective hair drying even at lower temperatures, and provides a wide range of temperature and speed settings. Models with intermediate power levels, ranging from 1000 to 1800 W, are more suitable for travel and on-the-go use.

For curling irons, electric curlers, and similar devices, the heating intensity and speed depend directly on the power. The manufacturer carefully selects the heater's power to achieve specific performance characteristics, such as temperature and heating intensity. When choosing such devices, it's essential to focus on practical indicators and compare different mode...ls based on power, especially if specific characteristics are not clearly stated, as seen in some inexpensive curling irons with basic functionality. In these cases, users should consider the weaker and more delicate their hair, the lower the temperature and less intense the heating should be. If unsure, it's safer to opt for a less powerful device, as it may take more time to curl hair, but it significantly reduces the risk of damaging the hair.

The specific working temperature settings that can be set on the device. A greater number of modes or a wider adjustment range offers more options and allows for a more precise adjustment of the device to a specific situation; on the other hand, expanded capabilities inevitably affect the price. When choosing a specific model, it's important to remember that the optimal temperature for a particular situation depends on a number of factors – hair characteristics, specific task, cosmetics being used, etc. Recommendations on this matter can be found in specialized sources; use them to determine the temperature you need and choose a curling iron, brush, or styler with the appropriate temperature settings based on that.

Note that if this point specifies a whole range of settings (for example, "120 – 220 °C"), it does not necessarily mean smooth adjustment is available; this detail needs to be clarified separately.

Blow-drying mode where warm and cool air alternate in one cycle, creating a gentler temperature flow while maintaining drying efficiency. It's notable for helping to remove moisture faster than just using cool air, while also reducing the risk of overheating hair and the scalp compared to constant hot air.

Unlike the separate "Cold Shot" button, which only provides short-term cold fixation, the combined mode is designed for prolonged use and comfortable styling, especially on fine or colored hair.

In practice, it is often chosen for everyday drying after a shower, gentle styling using a brush, and also when needing to dry the roots without over-drying the length and tips.
