Best Curling Flat Iron Buyer’s Guide

There are no shortages for hair styling tools on the market today, and the Hair Straightener or Flat Ironer is one among them.

Like others, the flat ironers are also more, but not all the products are reliable and easy to use and handle.

However, some of them may hold the features that you are looking for. It is because you need to consider some essential factors before going for it. Here we have listed the essential considerations to make during the purchase.

1. Temperature settings

The first and foremost consideration would be the heat settings, and if you are new to the flat iron, you should consider them without fail.

The different hair straighteners have different heat settings, so choosing the one with the adjustable feature is a must. The different hair texture and length requires different temperatures for a better finish.

However, you are advised not to go for over 420°F ranges and hold for over 10 seconds on each strand as they may damage your hair.

Always choose to apply the heat protection cream before beginning the styling process with a flat iron.

2. Plate material

The next consideration would be the plate material of the hair straightener. There are different types of plate material. Here are some important three different material types.


The plate with titanium is great in every aspect to expect its price and can heat up faster and reach a high temperature within seconds. This also can maintain the temperature that you’re switched to throughout the session.

The titanium plate flat iron is easy to clean and use, and the most rounded hair straightener for curls is titanium coated. This is ideal for someone with coarse and thick hair and for longer use.


The ceramic coated plates are great for one with normal or fine hair. They may take more time to heat up than titanium but distribute the heat evenly and preserve it well to the whole process. However, it is pretty pricey, worthier to buy due to its excellent aspects.


The tourmaline is one of the best options to style on frizz and unmanageable hair. It penetrates the hair follicles and keeps them calm, nourished and leaves no unnecessary hair damages.

3. Overall Size and Shape

Are you looking for a flat iron with versatility? Then, the hair straightener with rounded plates would be the best choice.

There are many sizes and shapes, but the round shapes are coupled in most of all flat irons as they can make your hair straightened with a smooth and shiny finish and leaves no kinks and creases on your hair further.

The square-edged irons, on the other hand, are good enough for straightening but not the one for curling hair.

4. Extra frills

There are so many cool features on different flat irons, but your needs and budget determine what you’ll need to buy. Here are some other features and considerations.

5. Far infrared technology 

The iron technology aids heat hair from the inside out and leaves no hair damages on your outer layer of hair. The floating plates claim to impart a good grip on your hair, leading to distribute the heat evenly until the entire process.

The dual- or tri-zone sensor technology also ensures whether the heat is distributed evenly at all times. The auto shut-off option turns off the ironer automatically when it’s not used after a certain period. So, it is likely to cause no accident even if you forget to switch off.

The dual voltage, on the other hand, helps to reduce the need to carry voltage converters everywhere. So, you can carry the flat iron with this option wherever you go to style your hair.

Curling Your Hair with a Flat Iron: Step-by-Step Guidance 

Are you a beginner? Then, this is the guide for you. With this, you can learn how to curl the hair with flat irons. And if you practice more after knowing this, you can grab salon-grade curls with flat irons.

First, you need to wash your hair with shampoo and conditioner and apply a heat protection cream or spray on your hair to prevent hair damages due to overheating.

Before starting, comb your hair without tangles and partition your hair that you want to curl. Clamp the hair section about its mid-length to make a perfect curl.

Curl any one of the side sections right at the hairline first and then repeat it for another side.

Massage the roots to break down the curls into small and if you want to add a homogeneous look, comb your hair with a boar bristle brush to get the job done.

Finally, use a setting or fixing spray on your curls to make them stay for longer.

Mistakes To Be Avoided While Styling Your Hair

Always choose the right barrel size because the bigger one does not work great on shorter hair. So, go for the flat iron with 1-inch-wide barrel size for small and medium and 1.25 wide size for longer hair.

Try to avoid any hair oil on your hair before curling hair, as it may weigh down your style or locks. Also, don’t use the straightener on the damn coat.

Don’t go for the high temperature on your first step. Gradually increase if you must require or try to avoid unnecessary hair damage, especially on dry or chemically treated hair.

Ensure you are keeping the tool on each strand for only less than 10 seconds for safety purposes of the hair.

Best Curling Flat Iron FAQ

In this section, you can find more relevant questions about flat irons for curling hair. We hope these will clarify your doubts about the flat irons.

  1. Is titanium or ceramic better for curling hair?

Choosing between the two completely depends on your hair type and length. The titanium flat ironer works excellent on coarse and thick hair, while the ceramic is the best for fine and chemical treated hair.

  1. What should I put on my hair before flat ironing?

Applying hair protectant before styling hair with a flat iron is crucial to prevent hair damages. You can also use a setting spray like thickening mousse is better after styling to make them last longer.

Final Verdict

Flat ironers are a multitasker tool, incredible in handy, and worthy of buying. If you are new to curling with a hair straightener and want to learn it easily, I would prefer the flat iron by RUSK. It is durable, reliable, affordable, more manageable, and style your hair faster than others.
