What is a tourmaline hair straightener?

Tourmaline is a material usually used to coat hair tools like straighteners, curling wands, and other tools.

It is a crystal boron silicate mineral, and although these terms may not mean anything to you, generally it’s a material that helps smooth down hair and minimize frizz.

The material releases negative ions that act against the positive ions in damaged or dry hair leading to smoother hair. It also helps seal in the moisture of your hair, so it won’t make it drier.

Who needs a tourmaline flat iron (hair types, etc)

Tourmaline flat irons are great for people who consistently dye their hair, have damaged hair, or dry hair. It works to seal in moisture, so your hair won’t be dried out.

This means your hair won’t get “crunchy” or have that burning smell present using other straighteners.

Tourmaline flat irons are also great for those who have thicker or coarse hair since this material helps spread heat more evenly.

Since the heat distribution of this material is better, that applies that you will require fewer passes with the straightener to get flat straight hair.

Fewer passes means less exposure to heat which means less risk of heat damage. If you use your flat iron daily, then a tourmaline flat iron is surely the one for you.

Tourmaline offers an added layer of protection which is great for daily use.

Benefits of using tourmaline straighteners

Less damage

Tourmaline is a great material for flat irons since it damages hair less than other materials. It emits negative ions which means all the positive ions around the hair are converted to negative ions.

This means the moisture of the hair is sealed into the shaft, and your hair won’t dry out.

Since dryness of hair is the culprit behind split ends and overall damage, using tourmaline straighteners means you will avoid a lot of heat damage.

Healthier look

This benefit is the logical continuation of the previous benefit. Since tourmaline straightener plates will trap moisture into your hair, your hair will look hydrated and sleek after straightening.

These plates will also add an extra layer of protection and smoothness to your hair, so you will have healthy-looking hair with no frizz or flyaways.

Works for all hair types

Another benefit of tourmaline flat irons is that they will straighten all types of hair, no matter the type.

Whether your hair is fine, dry, coarse, thick, curly, or straight, a tourmaline flat iron will give you great results.

The plates will easily straighten all textures of hair, so you don’t really have to consider your hair type if you are thinking of purchasing a tourmaline straightener.

What to look for in tourmaline flat irons (additional features)

Temperature settings

One of the best features to look for in a tourmaline flat iron is adjustable heat settings. Flat irons with a single temperature can be inconvenient since this temperature may not work well with your hair.

Straighteners with a few temperature settings, like most of the reviewed straighteners in the above-mentioned list, are best since you will find a temperature that works for your hair no matter the type.

Finer hair will require lower temperatures while thick hair or dyed hair will require higher temperatures for a sleek straight look.

Auto shut-off

If you are anything like me, and constantly forget whether you shut off your heat tools before leaving the house, then this is a feature you should look for in a flat iron.

Although this isn’t going to affect the actual hair look achieved at the end, it’s an added feature that will help you ease your anxieties.

With an auto shut-off feature, a straightener will automatically turn off after a specific amount of time, usually about an hour.

So, even if you did leave your flat iron on while in a rush to leave the house, you can go about your day knowing your straightener will turn off by itself.

Swivel cord

This is a feature that again isn’t going to directly affect your achieved look, however, it plays a large role in the actual straightening process.

With a swivel cord, you won’t have to constantly readjust your head or your chair to reach the backs of your hair.

As you move your arm, your straightener cord will move with you. This is a great feature especially if you have longer hair, so your arms will surely not get tired.

FAQ

Is tourmaline good for hair?

Tourmaline isn’t necessarily “good” for hair since it doesn’t have any major benefits, but when it’s present on styling tools, your hair is at a lower risk of heat damage since it seals in moisture and emits heat more evenly.

What is better titanium or tourmaline?

They are both great materials for styling tools. Titanium flat iron is better at taming thick and dense hair while tourmaline is great for damaged or dull hair since it provides an added shine after styling.

Do tourmaline ceramic straighteners damage hair?

Out of the straightener materials, tourmaline is probably one of the lesser damaging ones. Of course, using too much heat without heat protectant will damage hair no matter the material, but tourmaline tools are usually of higher quality and less damaging.

I hope I have now convinced you that no matter your hair type, a tourmaline flat iron is a good choice for you.
