5 Best Curved Flat Irons

by Gabbi

Hot styling tools in the haircare world seem to be ever evolving. Most of us all have that one drawer or cabinet in our bathroom that houses all of our styling tools jumbled together, tangled cords and all.

Finding tools that can create multiple styles easily is a helpful way to reduce the clutter in those drawers by one or two items.

Flat irons, commonly referred to as hair straighteners, have been one of the most popular heat tools for decades, along with its counterpart, the curling iron. The different sizes and shapes of both flat irons and curling irons work to achieve different styles and work on various hair types and lengths accordingly.

However, with all the hair tool innovation, the development of the curved flat iron has been discovered as a way to provide your strands with straight, wavy, or curly locks all with the use of one tool!

But, how do you find the best curved flat iron for your hair? When shopping for a new flat iron, you want to look at the plate material, as well as the heat settings, as the two main factors. Based on your hair type and preference, it will determine which plates and temperatures will be best for you.

With curved flat irons specifically, it is important for the plates to wrap around the sides of the iron in order to give the tool a curved edge to achieve wavy and curly styles, as well as straight.

Below we discuss the difference between regular and curved flat irons, along with a guide for the best curved flat irons for various hair types and textures!

Regular Vs. Curved Flat Irons

Most are familiar with the regular style of flat irons for the hair, the straight edges with flat plates to give you sleek, shiny locks. Although standard shaped flat irons serve their purpose, curved flat irons are a popular choice for those who want to option to straighten, curl, and wave the hair easily with one tool.

The curved edges of this style of flat iron works as a multi-purpose tool to deliver many different hairstyle choices, add volume at the root, and prevent unnecessary dents or bends in the hair that can occur when using a flat iron at hard-to-reach angles.

A curved edged flat iron will have plates that curve around the edges of the straightener, giving the tool “side plates” to offer continuous styling with minimal tugging.

With the plates that curve around the edges, it helps to curl or wave the hair, while the flat part of the plates can straighten the hair. The curved edges of the plates also allow the straightener to get close to the root to add extra volume.

What To Look For In A Curved Flat Iron

As with all hair tools, there are a few key features you want to look for to ensure it will work properly for your hair type and desired styles.

With curved flat irons, there are many similarities to regular flat irons in terms of what features you want to look for. Below are some factors to consider when shopping around for a curved flat iron.

Plate Material

The material that the flat iron plates are made out of are an important feature of your styling tool, because different materials offer different benefits, and you may find that one type works better for your specific hair texture.

There are three main materials that are used to make the plates for most flat irons, both curved and regular: ceramic, titanium, and tourmaline.

  • Ceramic plates are the most common material found in heat styling tools, especially flat irons, due to the even distribution of heat throughout the plates. Ceramic plates create a smooth, frizz-free finish for the hair and work well for most hair types, especially fine or thin hair.
  • Titanium plates are also very popular, as they work to emit negative ions throughout the plates as the material is heated. The negative ions help to counteract any frizz, texture, or dryness in the hair, making this an ideal option for those with dry, curly, coarse, or textured hair.
  • Tourmaline is a newer material to be used in heat styling tools, but has quickly increased in popularity. Often times, tourmaline and ceramic materials are used together, with the tourmaline coating the ceramic plates. The material is also meant to deliver negative ions and combat frizz, and works for most hair textures, especially when combined with ceramic.

While you can find flat irons with one of these specific materials, there are also many options that have a combination of material to deliver optimal results.

Heat Settings

Heat, or temperature, setting is another important element to finding the right flat iron for your needs.

Looking for an iron that will provide enough heat to style as desired, but not too much that will cause unnecessary damage. Depending on your hair type will inform how much heat your hair can and should be exposed to. 

Generally, most heat styling tools reach up to at least 400°F, however you might not need to use the tool at its maximum heat setting.

Thinner hair can benefit from lower temperature settings, while thicker hair may need more heat to achieve a sleeker appearance. Having adjustable heat settings, with a wide range of temperature options, helps to use the correct setting each time. 

Using a heat protecting spray on your hair before using any heat styling tool will protect your strands from extra damage, while still providing the proper distribution of heat to achieve your desired style.

Plate Size

Based on the style of your hair, its texture, and the style you are after, will help determine what plate size is best for you. Most flat irons, even curved ones, are available in larger and smaller plate sizes to best style different hair lengths and textures.

Smaller plate sizes work well for specific areas, such as bangs or pixie cuts, larger sizes work for longer hair lengths, and the standard one-inch plate size is versatile for most hair lengths and desired styles.

Even if you mainly prefer to keep your hair straightened, a curved flat iron can still work wonders for your hair based on its shape and design alone.

Because the plates curve towards the outer edge, it eliminates the chance of any unnecessary snagging or tugging of the delicate hair strands.

The curved nature of the iron can also add volume at the root, especially for thin or fine hair, by being able to curve and fit closely to the root without issue.

The options above run the range of heat settings, sizes, and plate materials to ensure each hair type and texture can find a tool that works for them.

No matter what hair style you are after, the innovative shape of a curved flat iron can help you achieve your desired look, while also helping to clear some space in your hair tools drawer as a bonus!
