Comparison Rowenta Expertise Liss & Curl Ultimate Shine SF6220 vs Philips Pro HPS930

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 length of the plate allows you to understand which curl can cover the device and how much to wind it.

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, allo...wing the curling 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.

The heating time of the plates to reach the desired temperature for hairstyling is an important factor to consider. The average heating time for models is around 30 sec. Models with longer heating times are considered to have higher numbers, while those with heating times of 15 seconds or less are considered to have fast heating, which is the best result for almost instant use. However, it's worth noting that fast heating time may have some impact on the power of the device.

— Concentrator. Nozzle used in hair dryers to narrow the air flow, providing a more directed and intense blowing. Usually, it has the form of a nozzle that “flattens” the air flow from round to flat.

— Diffuser. Nozzle that diffuses the air flow. Perfect for sensitive hair and prevents damage. Also, in some cases, provides more efficient styling.

— Brush. Comb-brush attachment, mainly used for hair styling. Brushes can have a different design — for example, there are both round (cylindrical), with pins sticking out in all directions from the nozzle, and more traditional flat ones. Pins can also have different lengths, density and be made of different materials.

— Straight. In this case, we mean a standard nozzle for curling irons (see "Device"). It is a cylindrical heating element designed for classic curling and most often supplemented with a hair clip, almost the entire length of the nozzle.

— Conical. A variety of nozzles used in curling irons. It is similar in design to the classic straight, but it has a conical rather than cylindrical shape, tapering from the handle to the end. In addition, such accessories usually do not have crimpers. The cone nozzle is more difficult to handle than the straight one, but at the same time it allows for more stro...kes and gives more space for creativity (in particular, the diameter of the curl can be changed by winding the hair closer or further from the handle).

— Spiral. Nozzles for curling irons with a spiral slot on the surface. When used, this slot plays the role of a guide — a curled strand of hair is placed into it, wound on a heater; the end of the strand is usually fixed with a small clamp near the handle. In a certain sense, working with spiral nozzles is easier than with traditional straight ones — in fact, there is a “tip” on the nozzle for the user, and for an effective and pleasant-looking curl, it is enough to follow this “tip”. On the other hand, the functionality of such devices is narrower — curled curls have a strictly defined shape, depending on the size and angle of the spiral turns.

— Double. Hair curler nozzle, consisting of two cylindrical working surfaces, each with its own heater. The design of such a nozzle can be different: in some models it looks like a characteristic “fork” with teeth of the same or different diameters, in others each cylinder is located on its own half of the crimpers, and the heaters are side by side when closed. Anyway, such a device provides interesting additional features that are not available with more traditional single nozzles; but the specific possibilities may be different, depending just on the design. For example, a “fork” allows you to create curls in the form of zigzags, and with the help of a clamp, you can form waves of a small volume, but strictly the same size. However, for a number of reasons, double nozzles have not received much distribution — the triple ones described below are more popular.

— Triple. Further development of the idea embodied in double nozzles. In accordance with the name, such nozzles are equipped with three working surfaces of a cylindrical (or similar) shape. Usually, the whole structure looks like crimpers, while the extreme heaters are on one half of the crimpers, and the middle one is on the other. Triple nozzles are used mainly for hair with small waves: they allow you to easily create numerous such waves, and all the bends will be the same size. And in separate curling irons — for the same purpose — not even three, but five heaters are provided, with a similar design principle (through one on different halves of the crimpers); such “five” nozzles are similar in purpose to triple ones, but their presence is specified separately.

— Straightener. Nozzle for straightening (smoothing) curly hair. Usually it has the form of crimpers with flat heating plates: a strand of hair is clamped between these plates, after which the crimpers are pulled along the entire length of the strand, straightening the hair.

— Hair crimper. Nozzle for giving strands a zigzag shape. It has the appearance of crimpers with characteristic corrugated plates. The shape and size of such plates can be different — accordingly, the laying result will also differ: zigzags can be sharp or smooth, large or small, etc.

— Heat resistant mat. A special mat made of heat-resistant material, on which you can put a heated tool without fear that the heated nozzle will damage the countertop. Thus, in short breaks during work, as well as during cooling, there is no need to look for an improvised stand or other way of safe placement. So a thermal mat can significantly "make life easier" for users — especially for those who use the tool often and a lot, for example, stylists in beauty salons. And in some models, these accessories also perform the function of a cover — for storing and transporting the device with set of nozzles. Note that heat resistant mats are mainly equipped with “contact” type tools, such as curling irons and stylers; however, such a device may also be supplied with certain models of hair dryers.

— Heat resistant glove. Protective glove made of heat-resistant material with low thermal conductivity. It protects the user's hand from high temperatures, which are often used when working with hair, and also provides some additional features: for example, with a hand in a heat resistant glove, you can straighten the curl right on the nozzle of the curling iron without fear of getting burned. Also note that curling irons equipped with such an accessory usually do not have their own clamp, and it would be difficult, if not impossible, to work with such a device without a protective glove.

— Cover/case. The tool for storing and transporting the device. It is customary to call covers products made of soft materials, cases — made of solid ones; the former are less bulky and can be folded compactly when not needed, while the latter provide better protection. The specific type of device should be specified separately, however, a complete cover/case will be more convenient than improvised packaging anyway.

Note that in addition to the above, modern curling irons and hair dryers may include other nozzles. However, these are usually rather rare accessories, mainly needed for some specific tasks, such as creating designer hairstyles.

A special loop that allows you to hang the device on a nail, hook or other similar device. In some cases, this storage method is the most convenient — for example, a hair dryer or curling iron can be kept on the wall near the mirror, in front of which hair is usually dried and styled, while the device will always be at hand and will not take up space on shelves or in drawers. The loop is most often located directly on the power cord, near the handle.

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.
