Best Flat Iron to Straighten Hair Comparison Table:

Different Types of Hair Straighteners

Although flat irons all look very similar, they are not all doing quite the same thing. Indeed, they have a wide variety of features and different technologies which differentiate them. It’s important to be aware of these differences before choosing the best flat iron that would be the most appropriate to your own unique needs.

Ceramic hair straightener

Ceramic has been the most popular material for flat iron plates since the beginning. This is because they heat evenly and don’t have heat or cold spot. This means that you are unlikely to burn your hair. Ceramic plates are also very smooth and glide easily through your hair. This means they won’t tangle, tug or damage your hair.

Be aware that some plates are only coated with ceramic but are in fact metal plates. Although these ceramic-coated irons are much cheaper, they won’t give you the quality of a 100% ceramic iron. We would recommend choosing a solid ceramic, or pure ceramic, iron to avoid the disappointment of a low-quality product.

Ceramic irons usually take a bit longer to heat up than the other types of irons. They have a good range of temperature options. They will make your hair shiny. They are not the best hair straighteners but are the most affordable.

A ceramic iron is your best choice if your hair is fine. They can be used at a fairly low temperature which is ideal for fine hair. They won’t burn or damage your hair. It’s also a good choice if your budget is very tight.


Tourmaline is a crystal-born silicate which has the ability to generate a lot of negative ions. This means that the natural moisture of your hair is protected and your hair doesn’t look dry. The negative ions neutralize the frizz. Your hair looks smoother, silkier and there are no flyaway strands.

Most of the time, tourmaline is coated around ceramic plates, which make them even smoother. There’s no damage made to your hair. Tourmaline also locks in the natural oil of your hair which protects your hair even more. Tourmaline irons work very fast.

It’s the latest material in flat irons and is still pretty expensive. Tourmaline irons are more durable than ceramic irons but not as durable as titanium irons.

They are good flat irons and could be a good choice for you if you have fine but wavy hair. They also work well for medium-textured hair. If your hair is thick or coarse, I would recommend you to look at titanium irons first.

Titanium Flat Iron

If you have ever read flat iron reviews, you would have noticed that there is always at least one titanium hair straightener in the top 5. Well, for the sake of your social life, I do hope that you don’t read as many of those that I do. The good thing is you don’t have to because I’m now going to share with you why titanium irons are top-rated hair straighteners.

The titanium irons have a very wide range of temperature settings which make them suitable for all hair types. The greater benefit is that these irons deliver a consistent heat. This comes from the fact that titanium is an excellent heat conductor. This minimum heat variation means that heat damage is greatly reduced.

Titanium has also a high ionic output, which is often enhanced with tourmaline, and the negative ions generated neutralize the positive ions of your hair. This leaves your hair incredibly sleek, smooth and shiny.

They have a greater versatility than ceramic iron and you will be able to straighten, curl and wave in a minimum amount of time. They also tend to heat up very quickly and reach a higher temperature than ceramic products.

The Best Flat Iron Brands

- Normal and medium hair: you can start at 1 1/4 -inch up to 2-inch depending on the length of your hair. You can use temperature between 360 and 380F. you can use any kind of plate.

As long as you respect these basic rules, you can choose any iron depending on your preferences, styling needs, and budget and even have the best flat iron for natural curly hair. You generally get what you pay for and if you want good quality, you have to pay for it.

Other important features besides temperature settings and plates are a swivel cord for ease of use and floating plates which don’t tug and break your hair. Curved edges are another great feature that will give your iron more styling versatility.
