Why buy a curling iron and a flat iron separately, when your flat iron with rounded edges can do both, curling and straightening for you?

Though the word “flat” in flat irons suggests that the tool is used for straightening the hair. It does not necessarily do that only.

But the real question is – which is the Best Curved Edge Flat Iron in the market? Well, the answer to this, is given by our in-depth reviews below. Check it out!

What is a Curved Edge Flat Iron?

As the term speaks itself, a curved edge flat iron is one that has curved plates rather than straight. They usually have slightly downward curved edges that make it easy to curl the hair and help in avoiding crimps.

With a round flat iron, you get the freedom to effortlessly curl your tresses in any direction, inward or outward. And their plates are made of titanium, ceramic, or tourmaline, just like the normal flat irons. 

Besides, curved flat irons are ionic, wet to dry, and universally usable. Therefore, you can always get silky smooth curls at any time!

Curved Edge Flat Irons Buying Guide

Although curved plate flat irons look similar to the regular ones apart from their plates. They do possess additional features that make it worth it to purchase these flat irons. 

If you are already looking to purchase a curved plate hair straightener, here’s what to look for in them.

Beveled Edges

As you now know that the curved flat irons have curved plates, what’s important to know is that the curves can range from an angle of anywhere between 15 – 70 degrees. These curves help in achieving your desired curls flexibly and smoothly. 

The best curved flat irons are those that are angled at 45 – 60 degrees. Whereas those having less than 30 degrees curve are not recommended.

But why does that matter? Well, when you have a well-rounded flat iron you don’t have to struggle much to curl your locks. They also give natural-looking curls without any dents or lines. Hence, it’s better to stick to a curved flat iron that is angled at 45-60 degrees.

Covering Sideways

Covering sideways is truly an amazing feature that allows safe styling. These are nothing but edges that are bent down sideways, which cover the lower part of the flat iron. They mainly help in even heat distribution across the plates.

Also, many-a-times you might have accidentally burnt your cheek while using a flat iron. This is usually due to the heat at the edges of the plates. 

However, with a round-edged flat iron that comes with covering sideways, the chances of getting burnt are significantly reduced.

Plate Shape Variations

Just like the regular flat irons, curved flat irons come with various plate shapes. Some curved hair straighteners come with plates that are steep in the middle part whereas others have plates inclined in any one direction. And there are some that have leveled plates.

The choice is yours! You can pick the curved straightener that would serve your purpose the best.

Additional Features

In addition to the features mentioned above, here are certain other things to check before buying a flat iron with curved edges.

  • Ionic technology: Flat irons built with ionic technology result in shiny, smooth styles that last longer.
  • Plate material: The material of the plates should be ceramic, titanium, ceramic tourmaline, nano-titanium, or titanium-tourmaline. These materials are capable of heating up quickly and retain heat for a longer time.
  • Plate size: The plate size of curved flat iron also varies. Generally, flat irons with a 1-inch plate size are best suitable for tight curls. And those with a wider plate size work well for loose curls.
  • Easy-to-handle: Flat irons which have a proper handgrip and are lightweight allow you to style without getting your hand fatigued.

How to Use a Curved Edge Flat Iron

As mentioned earlier, using Curved Edge Flat Irons is no big deal. They are pretty much easy-to-handle and operate. If you are an absolute beginner, then here’s how you can get started:

  1. Before beginning to style, make sure to apply a heat protectant serum or thermal spray. This will hold your style for a longer time as well as save your tresses from heat.
  2. Once you are done spraying the heat protectant, divide your hair into two equal parts. Then tie up one part so that it doesn’t come your way as you style the alternate side.
  3. Now divide the hair of the first side into a one-two-inch section and lay it on your flat iron.
  4. To create waves, wrap it around the beveled edges, hold it and bring it down through the hair.
  5. If you want large curls, wrap the hair strand around the edges and turn the iron over while going through the hair.
  6. Lastly, for a natural look, comb your tresses in the same manner as you are flat ironing towards the tips. And shape them as you like.
