The HSI Professional Glider Ceramic Tourmaline Ionic Flat Iron is the crown jewel on our list. Not just because of the aforementioned freebies you get with their current Amazon deal, but also because you get a lot for what you pay for. This is a salon-grade appliance with a technologically advanced design that combines luxurious ceramic tourmaline plates treatment, made to revitalize and nourish your hair, leaving it shiny and glossy post-styling. Tourmaline and ceramic plates are perfect for dry, coarse, and heat-damaged hair, giving it necessary moisture instead of depriving your hair strands of it. Tourmaline is currently the most trusted material for floating plates and is usually considered pretty expensive.

The anti-static ionic technology reduces frizz and flyaways, while the tourmaline-infused ceramic plates use the specially-designed 8 micro-sensors with HeatBalance technology to ensure heat is regulated and evenly spread across the device. This makes for extremely quick and safe styling, without hot spots that can potentially cook and ruin your hair. The HSI Professional Glider Ceramic Tourmaline Flat iron is also suitable for traveling, it comes with dual voltage, a drawstring pouch, and a travel-sized pure argan oil treatment, combining vitamins A, B, C, and D, which is perfect if your hair has been exposed to high heat.

Customers are also extremely happy with the adjustable temperature dial (frankly, it’s rare to find a cheap flat iron that will give you the flexibility of adjustable heat settings). The temperature varies between 140 F and 450 F, which is ideal for different hair types – whether you have curly, fine or thick hair texture, this product will be a worthy match. The 360 swivel cord will also prevent you from prom tangling and kinking the base of the cable, which is the usual flat iron’s Achilles’ heel. This HSI professional flat iron has 64, 421 reviews by buyers, 66% of which are rated with five stars. That’s what I call good performance!


  • Worldwide dual voltage – travel friendly
  • Thermal glove
  • Drawstring case for easy transportation
  • 360 Swivel Cord
  • Adjustable Temperature


  • No Auto shutoff feature
  • No temperature gauge, only a dial (which makes it easy to bump out of desired place)

Despite being slightly more expensive, the HSI Glider Gold Professional Flat Iron is also one of the top HSI sellers on Amazon. What impressed me even more was the absence of one and two-star ratings for this product, which is always a goоd sign! The HSI Glider Gold Professional Flat Iron not only looks fantastic, but it is upgraded with a microsensor temperature regulator distributing even heat across the plates of the device. This flat iron is the best way to achieve beautiful and lush results ultra-fast. The plates heat up in seconds and you can control the temperature via the gold temperature dial, allowing you to choose any setting between 170 F and 450 F. This makes it extremely suitable for all hair textures and types, and it will perfectly style bangs as well as long hair.

The HSI Glider Gold Professional Flat Iron also has beveled edges, which means you can use it to both straighten and curl your hair. This is great because you don’t have to limit yourself or spend more money on buying a separate curler. You can create versatile styles and all you have to do is flip the hair around the plates to achieve a wavy effect. The 1-inch ceramic tourmaline plates are great for additional heat protection, while the narrow housing assures you don’t kink your hair in odd angles. A large portion of the HSI professional flat iron reviews are positive and customers seem to be impressed by the sleek design and performance of this tool. Here are some other benefits (and a couple of cons) we don’t want you to miss before purchasing this flat iron:


  • 30-second heat-up
  • Thermal glove
  • Travel bag included
  • 1-year guarantee


  • Temperature controls aren’t precise
  • No auto shut off feature

3. HSI Professional Glider Mini 0.5″ Flat Iron – Best HSI Professional Travel Flat Iron

I I had to include a travel-size flat iron on this list because I know people are currently obsessed with them! Whether you’re coming back from your gym workout or simply traveling abroad, having a chunky and heavy flat iron will not only take up a lot of space, but it will also add to the weight of your carry-on or rucksack. This only limits you from bringing other essentials you might need on your trip or commute. So why not invest in a mini (and dare I say adorable) flat iron? The HSI Professional Glider with small 0.5-inch plates is the perfect space-saver. It is extremely lightweight – only weighs about half a pound and it’s smaller than an average adult hand. It comes with dual voltage, so it can truly go wherever you go (but I do remind everyone to buy a plug adapter as it is not included in the price). It’s perfect if you want to tidy up your mane after a workout or if your profession requires you to look presentable all the time. It’s so small you can put it in your bag and it won’t make a difference.

The HSI Professional Glider Mini Flat Iron also comes with 8 microsensors (4 in each ceramic tourmaline-infused plates), and guarantees beautiful results on your hair. Tourmaline produces a high volume of negative ions, allowing smaller water molecules to lock moisture into the hair, as opposed to any other hot tool that will suck it straight out. It is impressive that HSI has not compromised on the quality of the device and the materials it is made of, regardless of the small size. The technology used in this mini flat iron is up to standard. The only thing I can advise is to understand that a smaller plate size usually means thick, coarse hair can be difficult to style and will require some time. The same goes for long hair and it’s the only drawback these mini straighteners have. However, it’s possible to find good travel-size stylers. If we have piqued your interest you can learn more from our list of the top 6 travel-size hair straighteners of 2022 and gain an understanding of the different types of straighteners!


  • Extremely compact
  • Worldwide voltage
  • Great for short hairstyles and styling bangs


  • No auto-shutoff feature
  • No multiple heat settings

4. HSI Professional Glider Steamer Ceramic Flat Iron – Best HSI Professional Steam Flat Iron For Curly Hair

Plate material: Ceramic and Tourmaline | Weight: 1.8 pounds | Battery Life: N/A | Max Temperature: 450°F | Auto Shut-off time: N/A
  • Glider Steamer Ceramic Flat Iron w/Steam Dispenser
  • Free Argan Oil Steamer Liquid
  • HSI Style Guide

This is the first time I come across a steam hair straightener that can be used with argan oil treatment (or other oil of choice). If you’ve read my previous article on the best steam hair straighteners, you have probably noticed that not one of the straighteners on this list recommends using argan oil inside the water tanks of the straighteners. This is partly because oil can clog the steamer system. Yet it seems that the HSI Professional Glider Steamer Ceramic Flat Iron has no such issue. In fact, they even provide argan oil steamer liquid which you can use during the styling of your hair.

If you haven’t heard of steam hair straighteners and this sounds like completely new information to you, steam straighteners are perhaps one of the safest ways to style stubborn and curly hair. The people who most often use it will try to achieve sleek pin-straight results with a steam styler. But what exactly is it that steam straighteners do differently? Can’t you simply leave your hair wet and use a regular hair straightener? Absolutely NOT! What you probably don’t realize is that there is a little bit of biochemistry about this process. When hair is wet, it acts like a sponge. Not only is the core of the hair strand (also called medulla) made up of air and water (amongst other things) but the “stuffing” beneath the outer wall or cuticle of the hair is also full of moisture. When you start using an extremely hot hair straightener on wet hair that’s already absorbed water, you essentially start cooking it from the inside out . The water inside the hair strand starts bubbling up and breaking the walls of your hair strand. What we see with our naked eye is awful heat damage, flyaways and breakage, as opposed to a shiny and healthy-looking mane.

Steam hair straighteners work in a completely different fashion. They use steam, which isn’t harmful and actually adds moisture into your hair. That’s why so many customers love using steam straighteners if they experience issues with humidity. The hair has not only been straightened, but water has been added to it, much like a sponge has soaked up water, and no additional moisture from the air can enter the hair strands. That’s why steam straighteners also have apparent long-lasting results. Combine this with the extra protection of the ceramic-tourmaline plates and you have an extremely reliable tool on your hands. The only potential drawback would be that you’d have to refill the water tank often. But if you find that annoying you can always switch off the steamer feature and use it as it is. Here are some other nifty features of the HSI Professional Glider Steamer Ceramic Flat Iron:


  • Auto shutoff feature
  • Free argan oil treatment
  • Steam feature can be switched off
  • 1-year guarantee
  • Quick heat-up in just 60 seconds
  • Curved floating plates
  • Two heat settings – 360 F and 450 F
  • Suitable for all hair types, hair textures and lengths


  • No dual voltage
  • Steamer section could hold more water

HSI Professional Flat Iron Buyers Guide 2022

Voila! Those are the top four HSI Professional Flat Irons according to both customer reviews and my personal experience. I wanted to give you a general idea of how I selected these products and why I thought HSI was worth talking to you about:


Personally, I was pleasantly surprised to find a brand that sticks to providing affordable hair styling tools that have all the necessary functions of a professional-level flat iron. I think as consumers we are generally used to paying a lot of money and thinking that we’ll get the best product. Sometimes that’s not the case, especially with hair styling tools. I would personally say HSI Straighteners and stylers are an absolute bargain at the moment and you definitely pay for what you get. The fact that these tools are also best sellers on Amazon also speaks about the volume of people that could afford them and still be happy with the products. And that has to count for something, right?


HSI Professional Flat Irons don’t seem to compromise on the quality of their appliances either. This brand seems to have done their research. They use the least damaging materials in their flat irons, while also showing an understanding of the technology necessary to make their tools last long. Ceramic and tourmaline plates also allow you to straighten the hair at lower temperatures, thus protecting your hair from unnecessary heat damage. Dual voltage also seems to be an important element in the search for the perfect flat iron and HSI is happy to provide that. What’s great about the HSI Professional flat irons is they can be used as a 2-in-1 tool, so you can straighten, curl, add volume to your hair, or simply add some beachy waves to your hair. The hair texture also doesn’t seem to matter too much – whether you have thick, coarse hair or ultra-thin hair, it works well on all types. And because of this flexibility, HSI products can definitely be used in a salon. This makes the flat irons extremely versatile tools and in my opinion. These HSI models have all the necessary ingredients of a professional level styling hot tool.


Of course, I would be a fool to overlook this very obvious benefit. All HSI Professional Hot Tools come with some kind of freebie – whether it’s a thermal glove, a nice silky drawstring pouch to keep your flat iron in, or argan oil treatment, HSI definitely knows how to make a bargain. It’s a simple formula but it seems to work like a charm. The official HSI website also offers these freebies as separate products you can purchase (partly because you might run out of argan oil, or in case something gets damaged, I suppose) but it is extremely generous of them to be giving anything for free. Bear in mind that on their official website the thermal glove, argan oil liquid, and even the pouch are heavily priced. The freebies deal is currently available on Amazon so I’d recommend you jump on that offer ASAP!
