Top 5 Best Tourmaline Flat Irons Reviews

CHI Expert Classic Tourmaline Ceramic Flat Iron

CHI Expert Classic Tourmaline Ceramic Flat Iron
  • Tourmaline Ceramic Floating Plates
  • Adjustable Temperature Dial
  • Max Temperature 410°F
  • Dual Voltage + 60-minute Auto Shut-Off
  • Thermal Mat Included

A tourmaline hair straightener that’s compatible with all hair types? Sign me up! The CHI Expert Classic Tourmaline Ceramic Flat Iron is a longtime fan favorite for how smooth and silky it leaves hair, whether you’ve got a natural ‘fro or textured waves.

It does the job using an innovative ceramic technology that doesn’t just provide even heat distribution, but it also reduces static energy and helps tame frizz. Paired with tourmaline, the combo generates a high amount of far infrared heat (which is less damaging) and negative ions for sealing the cuticle layer and creating shine.

The floating plates also have a generous surface area with beveled edges that give you a nice, smooth glide.

I appreciate how fast it heats up, plus the 9’ swivel cord that rotates smoothly in all directions lets you maneuver around easily whether you’re working on your own hair or on someone else’s.

There’s a rotating dial for controlling the temperature setting (which goes up to 410°F). However, you do need to be careful when handling it because the placement on the edge of one side makes it easy to accidentally turn the temperature up or down.

  • Dual voltage – can be used anywhere in the world
  • Generates gentle but effective, uniform heat
  • Heats up quickly
  • Thermal mat included
  • Well-known and trusted hair appliance brand
  • Positioning of the heat control isn’t optimal
  • Max temperature of 410°F may not be enough for extra coarse hair types

FURIDEN 2-in-1 Tourmaline Ceramic Flat Iron

FURIDEN 2-in-1 Tourmaline Ceramic Flat Iron
  • 2-in-1 Tourmaline Ceramic Flat Iron/Curler
  • Twist Base Temperature Control
  • 5 Heat Settings From 250°F - 450°F
  • Rounded Exterior + Floating Plates

I love me a good multi-purpose tool, so the FURIDEN 2-in-1 Tourmaline Ceramic Flat Iron had me hooked for its ability to straighten and curl hair.

Granted, lots of gals already curl their hair with their flat iron, but the rounded outer barrel of the FURIDEN doesn’t snag or catch, or worse, leave dents or creases in your curls.

But let’s talk about how well it straightens too. It does a great job of smoothing and straightening, yet still leaves some volume and movement so you don’t end up looking like you’ve just flattened the heck out of your locks.

The other great thing about the tourmaline ceramic plates is that they are floating – meaning they tilt from side to side as you press hair between them. This is optimal because all strands are securely sandwiched between the plates no matter the angle you’re holding the iron, which gives a better glide and reduces snagging.

It comes with adjustable heat settings via a rotating base dial that both powers the iron on and off and lets you select a temperature setting from 250°F up to 450°F. It heats up nice and quickly and includes an auto shut-off safety feature.

It even comes with a couple of clips to hold your extra hair out of the way and a comb that helps you easily separate and detangle hair before straightening.

The one negative I’d mention is that the plates themselves are kind of short at less than 4” long. It would be the perfect tool if they were just a bit longer.

  • 2-in-1 flat iron straightens and curls hair effectively
  • Ideal for traveling
  • Comes with handy accessories
  • 6-month warranty
  • Smooth glide
  • Plates are on the shorter side
  • Not that many heat options

HSI Professional Glider Ceramic Tourmaline Flat Iron

HSI Professional Glider Ceramic Tourmaline Flat Iron
  • Tourmaline Ceramic Plates
  • Adjustable Heat Settings from 140°F-450°F
  • Dual voltage
  • Heat-Resistant Glove, Sample Size Argan Oil, Storage Pouch

The HSI Professional Glider Ceramic Tourmaline Flat Iron is perhaps best known as the most reviewed flat iron of all time on Amazon. So is it any good?

Overall, it’s quite decent, though it definitely depends on who you’re asking.

The 1” tourmaline ceramic plates have rounded edges, are able to tackle longer lengths but still manage to work for smoothing and styling bangs too.

It’s best for fine to medium hair types. Even though it has adjustable heat up to 450°F, some users don’t feel like it gets hot enough to straighten their hair.

Otherwise, it even manages to straighten 4C hair like a charm without snagging or pulling, and many feel like their hair looks healthier after straightening because of how silky smooth it gets.

In addition to ceramic and tourmaline technology, the HSI Glider uses advanced crystal plates and micro-sensors to regulate temperature and ensure uniform heat distribution. This helps prevent hair damage in the long haul.

What’s more, these technologies save you from having to do pass after pass on the same section, which is a huge plus for those with naturally curly hair.

And lastly, all the extras (cause who doesn’t love extras?): the HSI Professional Glider comes with a protective glove, a travel case, and a leave-in Argan oil treatment sample.

  • Wide heat range (140°F-450°F)
  • Textured handle for a non-slip grip
  • Requires fewer passes to straighten
  • Works well for curling and flipping too
  • Comes with a heat glove and travel pouch
  • The design is a bit bulky
  • Some users find the max heat not enough

INFINITIPRO BY CONAIR Tourmaline Ceramic Flat Iron

INFINITIPRO BY CONAIR Tourmaline Ceramic Flat Iron
  • Extra-Long Tourmaline Ceramic Plates
  • 30 Heat Settings Up To 455°F
  • 15-sec Heat Up + Tangle-Free Swivel Cord
  • Available in 1", 1 ¼” and 1 ¾” Widths

The INFINITIPRO BY CONAIR is one of the best tourmaline ceramic flat irons out there. It packs a set of impressive features enclosed in a unique construction that deems it worthy of a spot on this top 5 list. It’s equipped with extra-long floating plates that enable it to tackle a larger section of hair with a single glide.

From personal experience, this will save you a lot of time and frustration, especially if you have thick hair. Additionally, the slim design makes it easy to get between different sections with ease, and it glides like butter.

It also reduces static in addition to frizz, so you’re not left looking like you’ve just walked out of a science laboratory after you’re done. I love the slick purple design of the INFINITIPRO hair straightener because it looks very polished. 

This tourmaline flat iron has 30 temperature settings, heating up to 455°F in no time. To put your mind at ease, there’s also a safety shut-off function that automatically turns the iron off if you forget to unplug or shut it off.

Oh, and did I mention that the INFINITIPRO BY CONAIR Tourmaline Ceramic Flat is budget-friendly? You’re not looking at emptying too much of your wallet with this winner.

  • Extra-long plates can straighten more hair at a time
  • 30 temperature settings up to 455°F
  • Slim design easy to maneuver between sections
  • Affordable
  • Reduces static electricity
  • Handle can get quite hot

AmoVee Mini Ceramic Tourmaline Flat Iron

AmoVee Mini Ceramic Tourmaline Flat Iron
  • ½” Floating Tourmaline Ceramic Plates
  • Compact Travel-Size (~8" long)
  • One Temperature Setting - 410°F
  • Dual Voltage + Safety Lock
  • Swivel Cord + Heat Resistant Glove

There are several reasons to own a mini flat iron, and the AmoVee Mini Ceramic Tourmaline Flat Iron has them all checked. It’s lightweight, compact, and offers nearly the same quality as its full-size counterpart.

This little hair tool can be a real lifesaver if you want to straighten short hair, flip your ends, style bangs, or add some finishing touches. Not to mention, it’s easy to pack with you, fitting perfectly in small bags.

The AmoVee is an 8”-long iron with ½” plates that you can use anywhere in the world thanks to its dual-voltage capability. The impressive results are courtesy of the ceramic plates that are infused with tourmaline crystals to deliver a smooth and sleek finish.

Additionally, ceramic technology reduces the risk of hair damage from hot spots that can form on metallic surfaces. This mini tourmaline flat iron also comes with a heat-resistant glove to protect your hands when styling.

It heats up in 30 seconds, which isn’t too long compared to similar models. However, like most mini flat irons, the AmoVee only has one heat setting – set at 410°F.

If a good touchup iron is what you need – be it at work, after the gym, or on the road – the AmoVee is a great little appliance for the job.

  • Small size perfect for styling bangs and touching up flyaways
  • Ideal for short hair
  • Easy to pack and portable
  • Dual-voltage for worldwide use
  • Safety lock keeps plates clamped for storage
  • Not suitable for long or thick hair
  • Only one temperature setting

What Exactly Is Tourmaline?

Tourmaline is classified as a semi-precious stone. Technically speaking, it refers to a large group of crystalline boron silicate minerals compounded with elements such as aluminum, iron, magnesium, sodium, lithium, or potassium.

Tourmaline is also known to be the earth’s most colorful gemstone because it exists in a wide variety of amazing colors. In fact, tourmaline occurs in numerous shades of virtually every hue!

Many tourmaline color varieties have inspired their own trade name. For example, Indicolite is dark or greenish blue, whereas Paraíba is an intense violet blue sourced from the state of Paraíba, Brazil.

Tourmaline was first discovered in Brazil in the 1500s when a Spanish conquistador found a green tourmaline crystal and confused it with emerald. The confusion continued until scientists recognized tourmaline as a distinct mineral species in the 1800s.

Besides Brazil, tourmaline is also sourced from Maine and California in the U.S., China, Nigeria, and Namibia among other countries.

The mineral is believed to possess healing properties and is often used to repel and protect against negativity. It also serves as a birthstone for October and is used frequently in jewelry.

In hair appliances, tourmaline crystals have unique electrical properties when heated that help smooth hair and tame frizz. 

Advantages of Tourmaline In Heat Styling

Negative Ions = Positive For Your Hair

Generally speaking, when a flat iron says it’s made of tourmaline, it means that the straightener features ceramic plates infused with tourmaline. This combo boosts the production of negative ions when it’s heated up.

The emission of negative ions, often called ionic technology, helps reduce frizziness due to static electricity caused by positive ions. Tourmaline neutralizes positive ions by emitting negative ions, flattening the cuticle layer down and making your hair smooth and shiny.

Additionally, negative ions help lock in moisture so your strands don’t fry or dry out from high heat.

Are There Any Disadvantages?

In a word, no.

That said, you might find that some tourmaline straighteners are more expensive than plain ceramic ones.

However, there are still several affordable models out there that deliver reliable performance at a decent price.

How Does Tourmaline Compare To Ceramic Or Titanium?

As discussed earlier, tourmaline is almost always mixed with ceramic in flat iron plates. It’s rarely ever the only element present in the material makeup of the plates.

But how does tourmaline perform compared to ceramic or titanium?

Ceramic flat irons heat up pretty quickly and evenly, emitting far infrared heat that allows them to straighten hair at a lower temperature. This minimizes hair damage in the long run. 

Tourmaline ceramic flat irons heat up very quickly as well, but they’re especially effective when it comes to reducing frizz and static. You may notice more shine and generally healthier-looking locks after straightening due to the cuticle layer laying flat and reflecting more light off the strand.

As for titanium, it’s able to hold very high temperatures well, and heats up even faster than ceramic or tourmaline. It also has the advantage of being lightweight, non-corrosive, and more durable.

This characteristic makes titanium plates suitable for smoothing extra curly, thick, or coarse hair that’s typically harder to tame. If you have fine or damaged hair, you’ll want to stick to ceramic or tourmaline ceramic.

What Should I Look For In A Tourmaline Flat Iron?

Aside from plate material, there are a few other features you should consider when shopping for a tourmaline flat iron. These include:

Plate Size

Depending on your needs, you might want a narrower or wider plate. 1” plates are standard and work well for most lengths, but you can also find straighteners as small as ½” wide (such as the AmoVee Mini Flat Iron) for smaller jobs on bangs, or even men’s beards. 

On the opposite end, flat irons also come in plate widths as wide as 1 ½” to 2” wide for those looking to straighten longer or more hair at a time more efficiently.

Heat Settings

To tackle thick and coarse hair, you’ll need to look for high heat settings over 400°F. On the other hand, if you have damaged, fine, or thin hair, make sure you can adjust the heat to 300°F or less.

Adjustable heat settings – whether digitally or by control dial – are always a good feature to have.

Optional Features

Lastly, you may also want to consider options for safety and convenience. For example, an auto shut-off feature protects your countertop from melting (or causing a small fire), while dual voltage capability allows you to use the flat iron anywhere in the world.

Bottom Line

When it comes down to it, tourmaline flat irons offer unmatched ability to tame frizz and create lots of shine thanks to its capacity for negative ion production. 

My personal favorite is the tried-and-true CHI Expert Classic Tourmaline Ceramic Flat Iron for the quality and how well it straightens and glides. If you can swing the cost, it’s a worthy investment for a flat iron that can serve you well for years.
