However, simply buying a Tourmaline flat iron won’t work! You need to search for the one that suits your hair type and comes with features that give you glamorous results with the least effort.

In this article, we have picked the top 8 best tourmaline flat irons after researching all the market options. Check them out below and invest your money in the one that sounds great to you!

What is Tourmaline, and why is it used in styling tools?

Tourmaline is a gemstone found in various colors. It is crushed and grounded to dust to construct the plates of a flat iron or layer over another plate material. 

Tourmaline is mainly used in flat irons for the healthy results it provides. It produces negative ions, which eliminate frizz and static from the hair. It also protects the hair from heat damage and delivers shinier, smoother results. 

Typically, most flat irons contain tourmaline-infused plates, as tourmaline alone is quite expensive. When tourmaline is used in combination with other metals, the flat iron’s efficiency is increased.

What are the benefits of Tourmaline Flat Irons?

While Tourmaline flat irons come at a higher price than ceramic or Titanium ones, there are several advantages of using them.

The major benefit of using a Tourmaline flat iron is that it emits negative ions that reduce frizz and static electricity from your hair. These ions lock the moisture in your tresses and provide salon-quality styles even when you straighten at a low temperature.

Other than that, these flat irons suit all hair types. Whether you have dry, fine, coarse, or damaged hair, tourmaline flat irons will always give you excellent results.

Also, as Tourmaline flat irons maintain your hair’s health, you can use these flat irons to style your hair daily. 

Are there any drawbacks?

Though Tourmaline flat irons have plenty of benefits, they are expensive than ceramic flat irons. However, some companies give you Tourmaline flat irons at an affordable rate. So, you can do a little bit of research and find a flat tourmaline iron that fits your budget.

How to choose a Tourmaline Flat Iron?

Before purchasing a Tourmaline flat iron, you need to check whether it possesses all the features that satisfy your styling requirements. Some of the features to check are as follows:

Plates Coating Material (Only Tourmaline or Mix with it)

The plates of Tourmaline flat irons are usually made by infusing other metals (like titanium or ceramic) in addition to Tourmaline. While different materials suit different hair types and have their functionality, you should consider picking a flat iron that would work best for you. Otherwise, you may end up damaging your tresses.

Temperature Settings

The variable heat adjustment feature is quite helpful for the safety of your hair. It allows you to operate the flat iron at different temperatures. So, you can set it to the optimum temperature and style your hair without burning them. You can use it at a higher temperature for styling thick hair, whereas you can use it at a lower temperature for thin hair. 

Plate Size

The plate size of the tourmaline flat iron also plays an essential role during styling. The ideal plate size for your locks depends on the length of your hair. For longer hair, you’ll need a flat iron with wider plates, above 1-inch. At the same time, for shorter hair, narrower plates will do the job.

For Hair Type

Choosing a tourmaline hair straightener based on your hair type will deliver the best results and protect the hair from heat damage up to a great extent. If you have thick and long braids, go for a flat iron with ionic technology or infrared emission technology and a wider plate size. Alternatively, if you have short and fine hair, opt for ionic technology and narrower plate size.


Another point of consideration while buying a tourmaline hair straightener is its price. As mentioned above, tourmaline is expensive. Hence, tourmaline flat irons would cost you more than normal ceramic ones.

Also, some companies provide tourmaline hair straighteners at an affordable cost. But it is worth noting that not all cheap products will give excellent results. So check the product’s specifications and reviews before landing on a decision!

Additional Features

Apart from the features mentioned above, there are a few more things to look for in a tourmaline hair straightener.

  1. Cord length: Find out the size of the cord. Is it long, short, or cordless? Remember, longer cords that are 360-degree rotatable give you more maneuverability. 
  2. Safety features: Safety features such as automatic shut-off, cool silicon tips, lockable plates, etc., should be included in the straightener.
  3. Warranty: Check whether the company offers any warranty on the product. It will help you claim a refund or exchange the straightener if it gets damaged or stops working.
  4. Authenticity: Lots of people complain about receiving fake products while shopping. Make sure you don’t make the same mistake. Check about the product’s authenticity by looking at the reviews and packaging and avoiding buying fake products.

Tourmaline Vs. Ceramic Flat Iron – What’s the Difference?

Ceramic flat irons heat quickly and retain the temperature for a longer time. They also distribute the temperature across the plates evenly. So, you can also style your tresses at a lower temperature.

Further, ceramic plates are really smooth. Hence, your strands gently glide through the plates without getting snagged or pulled.

On the other hand, Tourmaline flat irons emit negative ions that lock the moisture in your hair and eliminate frizz and static. They are usually infused with ceramic to add shine to the hair.

Titanium Vs. Tourmaline Flat Iron – What’s the Difference?

While Tourmaline flat irons protect the hair from damage, they corrode faster. They also emit high temperatures than other flat irons. 

Titanium flat irons heat super-quick. They suit most hair types, including curly, thick, coarse except fine thin hair, and make the hair straight and smooth. However, do note that these flat irons are quite powerful. Hence, if you have damaged or delicate hair, you should consider some other flat iron.

Mixed Flat Irons Coatings

Some flat irons come with mixed coatings. For example, ceramic is infused with tourmaline, and titanium is infused with tourmaline. These flat irons are quite efficient as they provide the benefits of both materials. 

Tourmaline, when combined with ceramic, produces soft, frizz-free, shiny locks. While Tourmaline, when combined with Titanium, provides extra smooth and silky locks.


By now, you must have understood the benefits of using tourmaline flat irons. They come in different plate sizes and offer tons of other features that keep your hair healthy.

If you are having a hard time searching for the best tourmaline flat iron, we would suggest you opt for the RUSK Engineering Heat Freak Tourmaline Flat Iron. This one has variable heat settings, a lightweight design, and is available in different plate sizes. Therefore, regardless of your hair type, you can purchase this flat iron and walk with salon finish hairstyles every day!
