Shopping Guide: Everything You Need to Know About Curling Irons

While it is possible to curl your hair or get natural waves using a hair straightener, you’ll always feel more comfortable and obtain more efficient results with a curling iron. You may have doubts at first, and there may be many things you don’t know about using this hair tool. In the section below, we’ll answer the most frequently asked questions to help you get the right curling iron.

Do I need a curling iron if I have a straightener?

A curling iron will allow you greater speed, comfort and styling possibilities. Some people use a straightener to create waves or curls, but this is not what the tool was designed for and is more of a shortcut than proper curl creation. However, if you’ve tried both before, you’ll realize that curling irons are more ergonomic and comfortable. What’s more, it won’t take you as long to get the perfect curls with a curling iron.

The curls you’ll get with a straightener are nothing like what a good curling iron can do. We’re talking about curl types, shape and intensity. A curling iron will allow you to do anything from narrow, defined curls to the most natural, loose waves you could ever want.

What types of curling iron are there?

The good news is that there is a wide variety of curling irons on the market o choose from, and they are available in every price range, as well. This incredible variety of choice also means that it’s difficult to understand the workings and features of every single type of curling iron available, so making the right decision can be challenging. The following are the different curling irons you can find on the market based on their mechanisms:

  • Without clamp: This type consists of a cylinder to wind locks of hair around and an insulated handle. They come in different shapes: straight, conical or with beads for separation measurements.
  • With clamp: These are very similar to the models above. The main difference is that they feature a clip that holds your hair, making your work easier–you just clamp the end of your hair into the clamp and wind the iron around your hair.
  • Automatic: They are very easy to use, as they’ll grab your hair and roll it by themselves, but these take practice to use safely. People with shoulder or arm problems find these helpful.
  • Thermal rollers: The improved version of the traditional hair curlers, they are made from ceramic and are heated on an electrical base to get faster results. These provide very long-lasting curls.

What are the shapes of a curling iron?

Nowadays, these accessories come in all kinds of different shapes. There are several key factors that you should look into if you want to buy the right tool for your hiar and desired styles. These include comfort considerations and the curlstyle you’re looking to achieve. We’ve listed the main types in the table below:

Straight Conical With Beads Double or Triple
The cylinder has the same diameter along its entire length. The diameter of the cylinder decreases from the base to the tip. These are more difficult to use, but allow you to create different styles of curls. Its shape with small beads allows the hair to pass through easily, and creates different curls depending on the distance between the beads. They feature two or three straight cylinders. Ideal to obtain defined and natural waves.

What creates curl definition?

The answer is simple: the cylinder of the curling iron. It is literally the only thing that determines the definition or softness of your curls and waves. From the largest diameters (2 in) to the smallest (1/4 in), each type of iron is designed for a specific role and will help you get the end result you’re looking for.

You are advised to use a curling iron with a large diameter if you want big, soft, natural waves. On the other hand, if you have curly hair and want to give it more volume, or if you have straight hair but want very defined curls, small diameter cylinders will be your best bet.

At what temperature should I set my curling iron?

As you probably know, heat can damage hair. This is why the temperature at which you use this accessory is so very important. When it comes to curling irons, the ideal option is to choose one that allows you to regulate its temperature. That way, you can set it to the most suited temperature for your hair type and reduce potential damage.

Generally speaking, a temperature of 300/350ºF should be used for thin or damaged hair, while you can go up to 475°F if your hair is thick and heat resistant. In any case, do not exceed this temperature, or you’ll risk damaging your hair. These data are intended as a guide, and you should always know what’s best for your hair. Always start with a lower temperature and increase if it is safe to do so.

How do I use my curling iron?

Not all types of curling irons are used in the same way. For this reason, it is important that you read the specific instructions provided with your curling iron, as they may vary slightly from one model to the next–these instructions are made for each specific iron to work at its best, so don’t disregard them. That being said, there are some basic steps that you should always follow to get perfect curls. We’ve listed them right here for you:

  • Brush your hair so that it will pass smoothly through the curling iron.
  • Apply a heat protector before using your iron to reduce heat aggressiveness.
  • Choose the correct temperature for your hair type. You should start with a low temperature, as this will be more gentle for your hair.
  • It is easier and provides a better result if you divide your hair and curl it by small sections.
  • Clamp or hold the ends of your hair section onto the iron, then wind towards the roots.
  • Curl your hair in the opposite direction of your face for a more natural look.
  • Wait for your hair to cool down before letting it loose. That way, your curls will last longer.

Can I use my curling iron with wet hair?

This is not recommended. Since the curling iron uses heat to operate, you should avoid using it on wet hair. Otherwise, you’ll be increasing the already existing damage that heat does to your hair. This is why you should make sure your hair is completely dry and has had a protectant applied to it before using this accessory.

Some people say that hair tends to frizz out when blow-dried, so that curls you later create with a curling iron won’t look as good in the end if you dried with a blow dryer. For this reason, we recommend that you let your hair dry naturally to achieve the optimal level of smooth, natural-looking curls, if smoothness is more important to your desired style than volume.

What does it mean when they say a curling iron releases negative ions?

You may have already heard about negative ions in appliances such as curling irons, straighteners or hair dryers. They claim to prevent frizz and provide softer, shinier hair. Well, that’s actually true, and it’s all about balancing the charges in our hair.

Most of the products you use to care for your hair contain positive charges, which generates the static electricity you’ve probably heard of. Curling irons release negative ions to balance the charge and prevent frizz. This does indeed give you softer and shinir hair.

Shopping Criteria

There are several key criteria that you’ll want to consider when you decide to purchase your first (or tenth) curling iron. In the section below, we’ve detailed each of these factors for you. That way, you know what to look for when shopping and will always choose a quality curling iron that suits your needs and with which you will get the result you want.


This may just be the most important criterion of all. If you love to have perfect curls, your hair needs to remain healthy. Unfortunately, the heat given off by a curling iron isn’t exactly the best thing to take care of your hair. This is why it is essential for you to be able to regulate its temperature.

This will allow you to adapt your curling iron’s temperature to the style you wish to create or to your type of hair. This will lead to much better and more satisfying results, both aesthetically and in terms of hair care. Begin with a very low temperature and only increase as needed to enable your curls to hold.  Longer curling time at a lower temperature is better for your hair and creates longer-lasting curls.

The material your curling iron is made from is another key factor to take into account when choosing the iron you will purchase. This is very important because it will determine the amount of the hair friction in the device, as well as its ability to transmit heat to curl your locks more efficiently. Ceramic is the most frequently used material and is curently the standard of quality.

Ceramic offers little friction, facilitates smooth passing of your hair and heats evenly. Certain models also feature tourmaline, a mineral that releases negative charges and neutralizes the positive ions that frizz your hair.

Did you know that titanium curling irons are ideal for thick hair? Their high heat transmission increases their effectiveness.

Type and Shape of Irons

As you’ve probably noticed throughout our article, there is a wide variety of types and shapes of curling irons available out there. This is why these two criteria are so important to making the right purchase. First of all, make sure you know your hair type, as well as what styles you want to create with your iron.

Once you’re clear about this, it’s time for you to choose the type and shape of curling iron that best suits you. If you’re still having doubts, you can always read expert opinions on the matter, or even ask your by trusted hairdresser. It is also interesting to know which accessories you can add to your curling iron.


In addition to the type and shape of your curling iron, the size of the cylinder is also essential to get the results you’re looking for. The size you’ll see refers to the diameter of the cylinder. The vast majority of models will fall somewhere between 1/2 and 1.5 in, although you can still find larger or smaller if you’re not satisfied.

Smaller diameter curling irons will give you maximum curl, defined and with much more volume, but you will need to curl only small strands of hair at a time. Larger cylinders, on the other hand, will create softer and more natural waves, and you can curl more hair in each curl. Remember that the diameter can be written either in inches or in millimetres. We’ve come up with a quick equivalency table to help you:

Inches Millimetres
⅜” 9 mm
⅝” 16 mm
¾” 19 mm
1″ 25 mm
1.25″ 32 mm
1.5″ 38 mm
1.75″ 45 mm
2″ 50 mm

Comfort and Safety

We’re sure you’ll end up taking a true liking to using your curling iron. This is why it’s very important that you opt for a comfortable and safe model. This will be particularly key if you spend ten to fifteen minutes every day curling your hair!

Nowadays, most curling irons include an extra-long cable (at least 1.5 yards) that rotates 360º to prevent it from becoming entangled during movement. Modern models also tend to be very light, and feature a handle or loop to hang it up easily. All of these are nice extras to have.


Curling irons have taken hairstyling by storm, and they’re making our lives easier. Today, getting hairdresser-quality curls is so simple simple and can be done from the comfort of your own home. You’ll find curling irons of different types, shapes and sizes to suit your hair and tastes.

You can opt for the perfect curling iron, or buy a set that includes different cylinders so you have greater freedom of choice. You may also want some natural and casual waves. Whatever it is, this accessory will make it possible. So, what are you waiting for?
