Curved Flat Iron Buyer’s Guide

What is a curved plate flat iron and when it’s useful?

A curved flat iron has a curved shape instead of the traditional flat iron. The curve helps eliminate kinks and marks in the hair that flat irons are known for.

It’s best used when creating wavy or curly hairstyles, accommodating the twirling and swirling motions. They can also create straight styles, smoothing out locks and locking in moisture and shine thanks to ceramic-coated plates.

What options to look for in a flat iron?

When you start your search for hair straighteners with curved plates, there are a few things that you should keep an eye out for. As you browse for your perfect match, keep these features in mind:

The Plates

One of the most important parts of any flat iron is the plates. Depending on what they’re made of, they will better protect your hair and keep hair from frizzing or breaking while styling.

Some of the best plates on the market are coated with ceramic and have materials like tourmaline or ion-generating metals. The better the design and material, the more even heat will distribute and the less risk you’ll have of damage due to high heat.

Heat Settings

Speaking of heat, heat settings are another key feature to look for when searching for the perfect flat iron. The highest heat settings reach up to 450⁰F, which can work for courser hair.

Still, some hair types can’t handle that kind of heat, causing it to break and take on a dull and brittle appearance. That’s why you should search for irons that offer different heat settings, allowing you to choose the one that works best for your hair type and desired style.

Now, we’re not saying that you should only go for the high-end choices. Sometimes more cost-effective products knock high-end out of the water. The reason we mention brand is that it’s important to go with reputable brands that have a history of well-working and long-lasting products. Some of those are Babyliss, Croc, Solano, FHI, etc.

Most of those that stand by their products offer guarantees and warranties, which keep you protected in case there is something wrong with your flat iron.

Extra Features

Not that these are deal breakers but, when you have them, they make life a whole lot easier. A few extra features to keep an eye out for are:

Swivel Cords

Flat irons that have swivel cords are a plus, helping you have full freedom and flexibility as you twist and turn to create curls.

Automatic Shut Off

Forgetting to shut off your flat iron could be dangerous. Running at high temperatures all day could put your home at risk of a fire or could damage your all or furniture. Automatic shut-offs are an extra perk that helps to keep you safe.

How to curl with a flat iron with curved plates?

A c-shaped flat iron has a curvy shape that works with twirling movements to create curly and wavy styles. The shape helps to create smooth styles without kinks or sharp unwanted styling marks. To curl hair with a c-shaped flat iron, follow the steps below:

1. Prep Hair

Before using heat, always make sure that your hair is dry. Never use heating tools on wet hair to avoid damage and frizz. If working with freshly washed hair, blow dry first and make sure all of your hair is dry from root to tip.

Once hair is completely dry, it’s best to add a protectant to seal the hair follicle before you add heat and then, start the process of creating smooth and silky locks.

2. Create Sections

Next, part your hair into sections. Try and go for anywhere from three to six sections, making sure that you account for all of the hair on your head. Keep in mind, the smaller the section of hair, the tighter the curl.

You can tie sections up with a hair tie to keep them separate from one another and avoid mixing or just let them hang and grab randomly as you style.

3. Start Curling

Once your hair is prepped and sectioned, it’s time to style. Clamp the iron vertically and twist the hair back. Continue all the way down until you reach the ends and release. For a more natural and fuller style, twist strands in different starting directions, pulling some back and around and some forward and around.

Expert tip:
Test a few small strands at the back of the head first to get used to the motion and find the shape you like.

Can a rounded flat iron be used on all hair types?

As a professional hairstylist, I can tell you that a curved plate flat iron can be used on all hair types, but with some variations. Curved plate flat irons have a unique design that allows for more versatility in styling.

The curved plates are great for creating curls and waves, but can also be used for straightening hair. This makes them a great option for those with curly or wavy hair who want more control over their curls, as well as for those with straight hair who want to add some body and movement.

However, when it comes to hair types, it’s important to consider the thickness and texture of your hair. If you have thick, coarse hair, you’ll want to look for a flat iron with higher heat settings and larger plates to accommodate the thickness of your hair.

On the other hand, if you have fine or thin hair, you’ll want to opt for a flat iron with lower heat settings and smaller plates to avoid causing damage to your hair.

It’s also important to note that some flat irons have ceramic plates, while others have titanium plates. Ceramic plates are great for all hair types as they heat evenly and prevent frizz, while titanium plates are better suited for thick and coarse hair as they heat up quickly and retain heat longer.

In conclusion, while a curved plate flat iron can be used on all hair types, it’s important to consider your own hair’s thickness, texture, and the heat settings of the flat iron when purchasing one.

It’s always better to consult with a hairstylist before making a purchase to ensure that you’re getting a flat iron that will work best for your hair type and styling needs.

Are curved plate flat irons better than traditional flat irons?

The answer to whether curved plate flat irons are better than traditional flat irons is highly subjective. Both have their advantages and disadvantages, so the best option depends on your hair type, styling needs, and personal preference.

Traditional flat irons heat up quickly and evenly across the whole plate, making them easy to use and great for straightening large sections of hair at once.

The downside is that they can often cause more damage than curved plates due to the high temperature required for straightening. Curved plates offer a gentler approach because they allow you to wrap part of your hair around the iron before clamping down.

This not only reduces damage but also creates softer curls or waves with less effort. However, it takes more time and practice to master the technique, and it is difficult to straighten large sections of hair with a curved plate.

Ultimately, both types of flat irons can be used effectively as long as they are used properly. Whichever type you choose, make sure you’re using the correct heat setting for your hair type in order to avoid damage.

Beveled Edge Flat Iron FAQ

Why does my flat iron have one curved plate?

One of the reasons why the curved-shaped flat iron works to create curls and waves is the design. Most irons have one curved plate that pops up and another that caves in, fitting together perfectly.

As you add hair and pull it through the iron, the shape works to bend hair into a “C” shape, making wavy styles possible.

Also read:

Can I curl hair with a rounded edge flat iron?

Yes! As a matter of fact, this iron was made for curling and waving. Its design will allow you to twist and turn without worrying about kinks typical of styling with flat irons.

What should I pick for hair straightening: curved or ordinary iron?

For straightening the hair, a traditional flat iron is best. The flat plates help to smooth out the hair and get it super straight and glossy as you pull strands down.


Now, all that’s left for you to do is find your perfect iron. For an all-in-one styler that won’t let you down, the BaByliss Pro Nano Titanium flat iron has our hearts. No matter your hair type, length, or your desired twirly style, this iron will be there to help you achieve it.

  1. How do I use a beveled edge flat iron to create volume and movement in my hair?

    • You can use a beveled edge flat iron to make your hair look better. Wash your hair and dry it with a towel until it is only slightly damp. Divide your hair into sections. Clamp the flat iron close to the roots of a small section of hair and then move the flat iron up along the length of that section. To style your hair, twist your wrist outwards as you move up. This will make the edges of the hair plates turn away from each other. Do this until all sections have been styled. This technique creates more volume at the roots and is perfect for a variety of styles. With a bit of practice, you’ll be able to do salon-like styles from home!

  2. After years of struggling with my hair that simply refuses to curl, I was ecstatic when a new stylist was able to use their tool and give me beautiful curls. After trying to find the same product for myself without success, Amazon offered a saving grace – BaBylissPRO! Learning how to properly use it has been an enjoyable experience, but one that’s well worth the effort; now I can enjoy long-lasting curls with only minimal styling products. All in all, this tool made me so happy!
