Best Hair Straighteners with Ionic Function

The model belongs to the Karl Lagerfeld collection, which, as you might have guessed, was created in collaboration with the brand of the renowned designer and fashion designer. You would think the straightener should be expensive, but in fact, it's not: it has a low price tag and belongs to the mid-price segment, even closer to the budget one. The design, which the manufacturer calls premium, indicates its belonging to the Karl Lagerfeld collection. It features a classic black body with a signature design and silver and red inserts at the bottom.

The features can't be called premium either — it's simply a quality styler that is easy to use, performs its functions well, and is suitable for all hair types. The plates have a ceramic coating: this material is often used in styling devices due to its uniform heat distribution and gentle effect on the hair. They heat up in just 30 seconds, which is an important factor for people rushing to work or school in the morning. Additionally, the plates are floating, providing easy gliding and reducing excessive pressure on strands.

Additionally, the styler is equipped with a built-in comb located at the edge of the plate. As a result, the device first combs the strand, then straightens it. If necessary, this comb can be easily removed — for example, it would be inconvenient to make curls with it.

The straightener can work with any hair type thanks to 8 temperature settings ranging from 140 to 210 °C. Low settings are suitable for thin, damaged, and weakened hair, medium settings for normal hair, and high settings for curly and unruly hair. The selected temperature is displayed on a small screen, and during styling, the controls can be locked to prevent accidental changes to settings. Additionally, the ionization function helps maintain hair health: it makes them smoother and silkier, and prevents static electricity.

For convenient use, the manufacturer added a swivel base to prevent cord twisting and tangling, a hanging loop, an automatic shut-off function, and a heat-resistant case.

Philips has already mastered the production of quality styling devices, so it has plenty of proprietary developments for effective results and hair health preservation. The Philips 5000 Series BHS520 hair straightener has several such aces up its sleeve. The most important tool of the styler is its plates, so special attention was paid to them. Firstly, their length is increased to 105 mm to capture a wider strand at once, thus reducing the time spent on styling. Secondly, the most popular material — ceramic — is used as a coating, with the addition of argan oil. It improves glide, doesn't snag hair, and makes them silkier and shinier. Thirdly, the model has floating plates that move upon contact with the strand. This is done to regulate pressure on the hair and heat them evenly without overdrying certain areas. All this together makes styling faster and safer: users note that strands straighten after the first pass, and it takes only 10-15 minutes to create a hairstyle (although this depends on hair length and structure).

The styler heats up very quickly — just in 30 seconds after being turned on. That means you can just finish combing your hair — and it's ready to go. A big advantage is the temperature range from 120 to 230 degrees, as many people simply do not fit the standard settings of most models. For example, bleached, fine, and weakened hair requires the minimum temperature, while curly and unruly curls are unlikely to straighten at 180 degrees. That’s why there are 12 temperature settings to choose from. Additionally, Philips added ThermoShield technology — it's a special sensor that constantly adjusts temperature, preventing it from deviating from set settings and eliminating the risk of hair overheating.

Double ionization also takes care of hair health. A powerful system releases millions of negatively charged ions per session, which remove static electricity, eliminate fluffiness, and smooth cuticles. The work of these little helpers is not visible, but their result is noticeable: hair truly becomes smoother, more groomed, and shinier.

The straightener can be used at home or taken with you on foreign trips: it has the ability to switch voltage from 110 to 240 V, meaning it will work in many countries around the world. Also worth noting are such useful little things as a non-heating tip, closed plate lock, automatic shut-off after 30 minutes, and a hinge cord with a hanging loop. A nice bonus is the inclusion of a heat-resistant mat: it can be placed under the hot device during styling or turned into a case for storage and transportation.

Remington calls the model 2-in-1 because it can replace both your straightener and curling iron. But any straightener can curl hair, right? That's true, but here the secret lies in the shaped plates with a special curved design, which significantly ease the curling process. The unique construction and rounded body allow you to straighten strands or create natural curls with minimal effort, making the device especially relevant for beginners who can't get curls with a classic straightener. By selecting strands of different thicknesses, decreasing or increasing the duration of heating, you can experiment with the shape of the curl, creating more relaxed waves or voluminous coils.

The hairstyle holds quite well even without additional fixation products. Besides, due to its special shape, the styler looks attractive and stands out favorably against the background of monotonous competitors, as aesthetic pleasure from using a device is also an important factor, especially for a female audience.

Remington Curl & Straight Confidence S6606 is suitable for all hair types and ensures not to harm them during operation. Primarily, this responsibility falls on the floating plates with ceramic and tourmaline coating. They provide even pressure, ceramic ensures easy gliding, and tourmaline is a natural source of negatively charged ions with an anti-static effect. Thus, hair strands do not snag, heat evenly, do not over-dry, and don't get frizzy.

You can choose from 5 temperature settings with heating from 150 to 230 degrees, and the styler is ready to work just 30 seconds after being turned on. Users will also appreciate many useful details that turn the usually cumbersome styling process into a comfortable procedure: a display showing selected settings, an instant temperature boost function to the maximum 230 degrees, a lock preventing accidental presses and changes of selected settings, and a plate-locking clip.

Safety is ensured by an auto-off system that stops heating after 60 minutes if no button has been pressed during this time. Pleasant bonuses will include the memory function which remembers the selected temperature and sets it the next time you turn it on, as well as a heat-resistant tip included for convenient storage and transportation of the device.

The styler is not cheap, and there are several reasons for this. Firstly, the manufacturer BaByliss has earned a good reputation in the styling device market and is popular among professionals. Secondly, the model belongs to the category of professional devices, as indicated by the PRO appendage in the name. Of course, the straightener can be used at home, but it has some characteristics that are important for specialists.

First of all, it concerns the quality coating of the plates. It's an alloy of titanium and ceramic made with EP Technology 5.0. According to the manufacturer, such a coating is created using electrolysis technology, which is usually used in the production of jewelry and elite bijouterie. Its main advantages are more delicate treatment of hair, smoothness, strength, durability, and resistance to chemical agents. The last point is especially important for professionals who perform keratin straightening procedures and create hairstyles using sprays, foams, gels, and other styling products. The plates themselves are 28x110 mm, so they are wider and longer than most models (the classic size is approximately 25x100 mm). On one hand, increasing the working area reduces the time spent on styling. On the other hand, wide plates, like the pointed edges of the body, do not contribute to creating beautiful curls with the styler — creases may remain on the hair, and the hairstyle may not look neat.

To help you choose the optimal temperature depending on the features of your hair, BaByliss PRO BAB2091EPE has several modes. There are only 5, though professional equipment would be expected to have more flexible settings. The model offers temperature adjustment in the range of 150 to 230 °C with a step of 20 degrees. However, there is an Advanced Heat Management system that provides continuous temperature control and guarantees stable heating with an accuracy of half a degree. According to the manufacturer, the plates heat up in less than 50 seconds, but in practice, this happens even faster, and the surface becomes hot almost immediately after turning on.

Hair health is also taken care of by a powerful ionization system generating 150 thousand negatively charged ions per cubic centimeter. These ions help retain the natural moisture of the hair, prevent static, and add shine and silkiness.

To make using the straightener comfortable, there is an auto-shutoff function after 72 minutes and a long 2.7-meter cord with a rotating base that doesn't twist and doesn't require placement directly next to a power outlet. However, some details are still lacking, especially considering the price of the styler and its belonging to professional equipment. For example, it would be great to have a lock for fixing closed plates during storage or a heat-resistant case included.

Dyson's styler belongs to the premium segment and is priced accordingly, but this is not only because of the brand name but primarily due to the advanced capabilities of the device. The main feature is that it’s a 2-in-1 model, combining the functions of a standard hairdryer and a straightener. It can simultaneously dry wet hair and straighten it, as well as just straighten dry strands in case you need to refresh your hairstyle and style clean hair. And all this without damage — the styler does not use hot plates and high temperatures; instead, drying and straightening occur by means of a powerful air flow delivered under high pressure. The proprietary Dyson Hyperdymium motor provides a rotation speed of up to 106,000 revolutions per minute, thanks to which hair (even unruly and curly) dries and straightens with one, at most, a few passes.

In addition to this, hair health is taken care of by intelligent sensors regulating air flow temperature up to 16 times per second, and an ionization system for adding smoothness, shine, and silkiness.

The styler has extensive settings. The mode for wet hair offers three temperatures (80 °C, 110 °C, and 140 °C), for dry hair — two parameters (120 °C and 140 °C). There are also two power modes (weak and strong air flow), cold air mode and Boost for enhanced heating.

All selected settings are displayed on a small color screen. In addition, it shows notifications about malfunctions, overheating, the need to clean the filter, allows you to change the language, and even reset the device to factory settings.

The model's advantages don't end there, as the manufacturer added many additional options for convenience. Plate locking in the closed position allows not only compact storage of the styler but also its use as a conventional hairdryer, without placing strands between the plates. Idle mode automatically reduces and increases air flow when opening and closing the plates respectively, i.e., increases power when the strand is inside and decreases it during breaks. Automatic pause stops the device if left for more than 3 seconds with the plates open. It will restart as soon as you pick it up. Standby mode turns off the device if it is not used for more than 3 minutes. The power cord, almost 3 meters long, doesn't limit movement and allows styling wherever convenient. The included non-slip thermal mat can be used during operation or for storing the styler.
