Comparison Laifen Swift vs Remington Keratin Therapy Pro S8590

— Hair dryer. Classic hand-held hair dryers are devices that produce an intense air flow (with or without heating). Can be used for both hair drying and styling.

— Hairdryer (wall). Stationary hair dryers are wall-mounted devices that consist of the hair dryer and a wall stand. This design offers convenience, particularly in settings like beauty salons or public pool changing rooms. The stand allows users to keep the hair dryer easily accessible and frees up space on countertops or other surfaces. Additionally, the stand can accommodate extra features, such as an electric shaver socket, providing added functionality and practicality.

— Hairdryer-brush. Small appliances with nozzles in the form of round combs-brushes, supplemented with holes for air supply. They have a relatively small power and are used mainly for certain types of styling.

— Styler. Classic stylers, commonly known as straighteners, use heated tongs to straighten hair. However, these stylers are versatile and not limited to straightening alone. They can be equipped with various types of nozzles to achieve specific styling effects, such as hair crimping. Additionally, there are specialized stylers designed for unique purposes, like creating braided hairstyles.

— Multi-styler. Multi-stylers are versatile hairdressing tools used for styl...ing hair and creating a variety of hairstyles. They are composed of a heating base and interchangeable nozzles, each designed for specific hairstyling techniques. The device set may include curling irons of different sizes and shapes, straightening plates, curling nozzles, brushes for adding volume to the roots, and more. Essentially, multi-stylers are an upgraded version of stylers, offering an expanded range of complete nozzles for versatile hairstyling options.

— Curling iron. Hair curlers typically feature a round (cylindrical or conical) heating element onto which the hair is wound during use. Some models come with a clip to secure the hair tightly to the heater, while others may not have this feature. The diameter of the heating elements can vary, offering the flexibility to achieve various styling effects. Additionally, specific curling irons are also available, such as those equipped with a double heater and a clamp for enhanced styling capabilities.

— Automatic curling iron. Automated hair curlers function similarly to regular curling irons but come with a key difference: they automatically wind a strand of hair onto the heating element using a built-in motor and give a signal when the heating is complete. This feature makes them extremely user-friendly, as users don't need to manually wrap their hair around the curling iron or time the heating process. However, these devices tend to be expensive and relatively heavy, making them less convenient for self-use. Moreover, the automation is limited to standard programs and may not be suitable for creating complex or unique hairstyles.

— Brush. Outwardly, such devices most often look like combs, brushes, complemented by built-in heaters. Due to this, when combing, such devices are more effective than conventional brushes without heating, especially with thick “naughty” hair.

—Electric curlers. Curlers are small cylinders used for curling hair. They can be heated for more long-lasting styling. Electric rollers, as the name suggests, use an electric element for heating, typically built into the container where the curlers are stored. It takes approximately 10-20 minutes for them to reach the desired temperature, and the curlers themselves are made of heat-absorbing material that retains warmth for an extended period.

In addition to individual hair styling tools, there are also sets available that include two or three items, such as a "hairdryer + curling iron” combination. These sets consist of separate devices that can be used independently of each other. Purchasing such a kit is often more convenient and cost-effective compared to buying the tools separately. However, it also means relying on the manufacturer's selection of items, whereas individual tools can be chosen according to personal preference and needs.

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.

— Joint. In models with joint adjustment of power and “degree” of air flow, the parameters change at the touch of a button. Hair dryers usually have several fixed values of blowing intensity and air temperature.

— Separate. Separate heat and temperature controls give you more freedom of choice when using your hair dryer and styler. The parameters of the flow force and temperature for hair dryers with separate adjustments change separately, which allows you to count on the optimal values of power and “degree” of blowing to avoid overdrying your hair.

The number of power modes provided in the design of the tool.

This parameter is relevant primarily for hair dryers of various types (see "Device") — in models of another type, the main point is the temperature modes, see below for them. And in hair dryers, the number of power modes is, most often, the number of speeds at which the “blower” can operate.

The abundance of speeds allows you to choose the best option depending on the current task (quick dry, delicately style), hair type, etc. At the same time, the abundance of adjustments complicates the design and affects the price. Therefore, for domestic use, 2 – 3 modes are usually quite enough, and sometimes one is enough.

Note that in single-speed hair dryers, the number of modes may not be indicated at all.

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.

Specific operating temperature that can be set in the device.

This information pertains to curling irons, stylers, and other hair devices that come in direct contact with the hair during use. If the paragraph contains multiple values separated by commas (e.g., "160, 180, 200 °C"), it indicates that the device has several fixed temperature modes (in this example, three). On the other hand, if a range is given (e.g., "120 — 220 °C"), it means the model offers smooth temperature control.

Having more modes or a wider range of temperature adjustments in a hair device provides users with increased flexibility and precision in adapting to different situations. However, it's important to consider that advanced features inevitably come with a higher price tag. When selecting a specific model, it's crucial to keep in mind that the optimal temperature for each situation depends on various factors such as hair characteristics, the specific hairstyling task at hand, and the type of hair products used. Special sources can offer recommendations on suitable temperature settings. Therefore, it's advisable to determine the required temperature range based on these recommendations and then choose a curling iron, brush, or styler that offers suitable adjustment options.

The width of the plate in the styler or other tool with a straightener or hair crimper (see "Nozzles").

It is necessary to choose a tool according to the width of the plates, first of all, taking into account the length of the hair. So, for short strands, narrow plates up to 25 mm wide are suitable, but with thick long hair it is most convenient to use wide plates, from 30 mm or more.

Type of outer coating of the heating element.

— Chrome plated. The most basic and widely used coating option is chrome. It is affordable and heats up quickly. However, using chrome-coated heaters can pose a higher risk of hair damage, so caution is needed when using them. Due to this risk, chrome-coated nozzles are not ideal for frequent or continuous use.

— Aluminium. Such heaters are considered more advanced than the chrome ones described above, due to a longer service life and better heat distribution. However, it is not without the characteristic drawbacks of any metal coating, primarily the negative impact on the condition of the hair.

— Titan. Another option for a metal heater. In terms of basic properties, it is almost completely similar to aluminium (see above), in most cases it differs only in appearance.

— Ceramics. The main advantage of ceramics is the better distribution of heat than in metal heaters. Due to this, such a coating is considered much more “gentle”; however, its cost is noticeably higher, and heating is slower.

— Tourmaline. In most cases, when referring to a ceramic heater, it is typically combined with a tourmaline coating. This coating serves two primary functions: ionization, which promotes smooth and even styling, and friction reduction, allowing the cur...ling iron to glide through the hair effortlessly.

— Titanium ceramics. A specific type of ceramic coating used by some manufacturers. The design, usually, implements various additional technologies designed to improve the quality of work; however, whether such devices outperform "ceramic" analogues depends on the model in each specific case.

— Titanium-tourmaline. An analogue of the tourmaline coating described above, in which titanium is used as the base of the heater instead of ceramic. There is practically no difference in the main features.

— Steel. The most basic and common coating option is "ordinary metal plating," typically referring to steel. The main advantage of this surface is its low cost. However, the heating can be uneven and harsh, which demands careful handling of the tool and makes it less suitable for frequent use.

— Teflon. Teflon stands out for its low friction, making plates glide effortlessly through the hair, even more so than ceramic ones. However, in terms of heating uniformity, it slightly lags behind ceramics.

— Copper silicon. Typically, the reference is made to silicon-coated copper plates. Copper offers excellent thermal conductivity, ensuring uniform heating, while silicon provides practical properties similar to ceramics, such as a gentle effect and suitability for frequent use. However, this option is relatively specific and does not offer significant advantages over more traditional materials, which is why it is relatively rare.

— Manganese-copper. The manganese-copper coating on the heating plates offers a very gentle effect on the hair. These flexible plates allow the styler (straightener or curling iron) to adapt to the shape of the hair strand, reducing mechanical stress on the hair and minimizing damage. As a result, the hair becomes more manageable and obedient.
