Do you love sleek, straight tresses but are worried about the damage the heat causes to your hair?

Well, then you should invest in an infrared flat iron!

Unlike traditional straighteners, infrared flat irons are gentler on the hair and use less heat. That means the chances of heat damage get minimal. Especially if you have colored, damaged, or highlighted hair, it’s best to use an Infrared straightening iron.

However, as there are plenty of options available in the market, you’ll indeed have a tough time choosing the best infrared flat iron. Therefore, scroll down to check our favorite products and learn more about selecting the best one!

Considerations When Choosing Infrared Flat Irons

As the hair texture and styling requirements vary from person to person, it’s necessary to find out the perfect infrared straightener for you. Below, we’ve discussed the features to look for in an infrared flat iron to get you started. 


Infrared flat irons are not much expensive. You can find a hair straightener at a cost as low as $20 and an expensive one for more than $150. Also, the features included in the straightener may vary based on the price you pay. 

However, the point of consideration is that you should not settle for a cheaper one just because you’re getting it at a low cost. Instead, you should check its durability, features, and most importantly, see if it’ll suit your hair type. Otherwise, you may regret your purchase!

Infrared Irons With Titanium Or Ceramic Plates

Infrared straighteners come with Titanium or ceramic plates. Ceramic heats up quickly and distributes heat evenly. It reduces frizz and allows smooth gliding. It gives excellent results on both thick and thin hair.

Titanium straighteners also heat up quickly, but they are more powerful than ceramic. They conduct heat uniformly and are more durable. Hence, they work great on thick or coarse hair.

Infrared vs NON-Infrared

Plate Size

You can get Infrared flat irons with plate sizes of 0.5”, 1”, 1.5”, 1.75”, and 2”. Flat irons with smaller plates are excellent for travel, and those with 1-inch plates are good for thin, fine, short-length hair. Simultaneously, hair straighteners with more than an inch wide plates are best for thick, coarse, long-length tresses.

Adjustable Temperature Settings

Infrared flat irons that provide you with variable heat settings give you more control over the temperature. Such hair straighteners let you select your preferred temperature so that your hair doesn’t burn due to excess heat.

Some flat irons let you change the temperature in increments of 10F or greater, while some let you change it precisely. Some infrared flat irons also offer high, medium, or low settings, which give you limited control over the temperature.

Other Features

Apart from the features mentioned above, you need to check a couple of other points as listed below:

  1. Automatic shut-off: This feature is crucial in terms of safety, as it automatically turns off the hair straightener when you leave it unattended to prevent electric shock.
  1. Temperature controls: Infrared flat irons allow you to change the temperature settings by rotating a dial, pressing buttons, or digitally. For beginners, hair straighteners with buttons are more comfortable to use.
  1. Length of Cord: Straightening irons with long, tangle-free cords make it easy to style even the trickiest parts of the head, whereas shorter ones need you to stand close to the power socket.
  1. Beveled-Edges: Flat irons with beveled-edges give you more styling versatility. You can create curls, waves, or flip your hair in addition to straightening with such hair straighteners.

Is infrared safe for hair?

Yes, Infrared heat is perfectly safe for your hair as it penetrates at low heat levels and dries the hair from the inner side. It even boosts the health and shine of the hair by emitting negative ions. With infrared technology, your hair gets less damaged and becomes frizz-free. And such flat irons style faster than traditional flat irons. Hence, infrared is safe to style the hair.

How is infrared heat different from conventional heat used in flat irons?

Infrared flat irons differ from conventional in terms of the heat they use to straighten the hair. These straighteners mostly have ceramic or titanium plates, which heat up quickly and distribute heat evenly. So you don’t have to style over the same section repeatedly. They also cause less damage to the cuticles by styling them from the inside out.

Can I use an infrared flat iron on wet or damp hair?

No, you should never use any flat iron to straighten wet or damp hair. If you use it, it will cause damage to the hair and make it frizzy. It can even damage the plates of your flat iron. Therefore, never use your infrared flat iron on wet or damp hair.

But if you want to use it on wet hair, you should try a wet to dry flat iron.
