Curved Edge Flat Irons Buying Guide

What Is a Curved Edge Flat Iron?

Curved Edge Flat Iron

The term ‘Curved Edge’ says it all, quite simply. Rather than being straight, the edges of the plates of a curved edge flat iron are bent down, sometimes a bit, sometimes a lot. Among various hair straightener types, this is the only one categorized by the plate shape.

Why curved edges? When you’re up to making curls with a flat iron, those rounded plate edges make it easier for you. They allow much smoother maneuvers than the regular ones, so you get the freedom of moving it every direction without irritation.

Other than these traits, a curved edge flat iron is pretty similar to the straight ones. Like the regular flat irons, their plates are made of titanium, ceramic, or tourmaline. Also, a curved hair straightener can be ionic, wet to dry, travel-friendly and such. So what differences the curved edges bring? Stay with us, and you’ll know.

Who Can Use It?

As we’ve said before, a curved edge flat iron comes with better maneuverability than a regular one. It means you can move it as you wish. It doesn’t require you to be a professional to use it. It’s a user-friendly hair styling device even for the beginners.

A hair straightener with rounded edges suits every hair type and provides numerous style options in no time. You can achieve straight hair, smooth curls, flips, waves, and plenty more. Whether you’re a beginner or in a hurry, it’s the best solution out there to get quick and efficient results effortlessly.

  1. Maneuverability: The curved edges beat the rest of the hair straightener types with the maneuverability it offers. The beveled edges allow the plates to move free and smooth without any hassle. You can twist and curl or spiral your hair around easily even if you’re a beginner.
  2. Volume: To add adorable volumes to your hair, whether it’s fine or thick, there’s no better maestro than a curved edge flat iron. Especially with a steep plate, achieving perfect volumes is a piece of cake.
  3. Style Options: Where your regular hair straightener limits the style option to only straightening or frizziness reduction, a hair straightener with curved edges lets you style beyond any limit. You can achieve straight hair, smooth curls, flips, cute beach waves, sleek and healthy-looking hair and so much more.

Other than the benefits mentioned above, a good curved edge flat iron provides burn and damage protection to your hair, dent-free straightening, and even surround heat for perfect luster.

The Distinctive Features of a Curved Edge Flat Iron

The curved hair straighteners do boast some distinct features that distinguish them from the regular ones. Let’s have a quick look at them.

Beveled Edges

Flat Iron Curved Edges

It’s a trait that mainly differentiates a curved edge flat iron from a regular one. After all, they’re the reason why we call it a curved edge. The curvature of the sloped down edges can range from 15-70 degrees.

When your hair straightener comes with rounded edges, you get to maneuver it with more comfort. But to avail this benefit, the straighteners should have beveled edges angled within a suitable range. 45-60 degrees is the range that we suggest in this regard.

Because, when the edges of your iron are angled at less than that range, like 30 degrees that most of them come with, you hardly get the privilege. It’ll act much like a regular one than a rounded one, and you won’t get to move it smoothly through your hair strands. Besides, similar to the regular ones, leaving dents and lines on your hair would be a possibility when you wrap your hair around it.

And annoyances will follow you the other way around as well. When the angles are more than 60 degrees, it’ll be more of a curling iron than a curved one. As a result, you’ll have to struggle while straightening your hair. And even if you get to straighten it, the results won’t be long-lasting.

But when your iron has edges angled at the range of 45-60 degrees, you get all the privilege of a straightening iron, and it’ll provide you with almost all the same benefits like a curling iron as well. So, doing both of their jobs becomes a piece of cake.

Covering Sideways

The upper part of some of the curved edge hair straighteners comes with bent down sideways that cover the lower part. They ensure getting a better hold of your hair and even heat distribution. Not only that, but they also protect your skin from burning in case the iron touches your cheek accidentally.

The risk of burning your cheek is much of a possibility when you’re using a regular straightener that lacks such sideways, especially if you are a beginner. It’s a feature available only in hair straighteners with rounded edges that eliminates any chances of possible burns. And they enable you to try out various curling iron techniques.

Plate Shape Variations

They come with different plate shapes along with beveled edges. The plates can be steep in the middle section, inclined from a particular direction, or simply leveled.

Few Additional Features

Why We Do Not Recommend

Healthy Care Professional 2-in-1 Ceramic Flat Iron

Healthy Care has brought this budget-friendly professional 2 in 1 tool that is compact in design, thin and small, and easy to carry. The straightener produces a shinier finish on fine hair. It heats up as fast as 15 seconds and features a 60 minutes auto-shutdown functionality.

The features are pretty convenient and come real handy for the professionals. Yet we couldn’t consider this hair styler as an ideal curved hair straightener.

First of all, the flattening iron comes with 30-degree angled beveled edges which don’t meet our standard value. As a result, you won’t get to maneuver it as smoothly as you should have.

The iron acts almost similarly like a regular one with the surrounding parts next to the edges making it harder for you to create curls. Also, creating front fringes with it takes as much effort as a regular flat iron. It’s definitely not what the rounded edges are meant for.

And for its lack of bent down upper sideways, the movement becomes more limited since you can’t get a firm enough hold. Especially when you try to add disparate volumes to different sections of your hair, you must put a lot of effort.

HSI Professional Titanium Tourmaline Flat Iron

If you’re a hair-style hobbyist and regularly keep up with the trend of hair products, HSI is a name you must have come across. The well-renowned brand has been producing quality hair products for years.

This 1-inch professional curved flat iron with titanium tourmaline plates is another quality addition that works great on coarse hair. The product comes with some essential features including ionic technology, adjustable heat settings from 240°F- 450°F, and quick heat up.

However, the tool doesn’t stand up well as a rounded edge flat iron. It’s a great tool if you buy it for straightening your hair, but the style variations will be much limited.

The iron comes with beveled edges angled at 30 degrees, falling short from our standard value. Even though the edges have no surrounding parts, getting desired results will take more effort and time when you try to create beach waves or flips.

Moreover, the tool lacks bent down sideways in its upper body. It’s a flaw that’ll annoy the users, especially beginners when they’ll struggle to get hold of the wrapped around hair making bouncy curls. And the possibility of burns to both their hair and skin is always there.

How to Use a Curved Edge Flat Iron
