3 Different shapes of the barrel and its benefits?

There are several options in barrel shapes. So people can choose as per their convenience. Generally, the three types of curling wands are cylindrical barrel built-in clip, tapered barrel with a thick base and narrower at the tip, and the basic cylindrical tip that has even shaped. These curling irons are known for creating different sized curls, and they are used for different occasions.

But if you are a novice in this curling tools game, I recommend going with the basic one. I feel it’s great to treat yourself with a fancy, seven, or 10-in-1 hair curler set. But, if you are adventurous, then interchangeable barrels will definitely come in use.

#1. Cylindrical barrel with a built-in clip

This is the most popular one as the built-in clip makes it easier to style the hair. This curling wand comes in a straight, cylindrical barrel with a clip in the front that can be closed and open with the fingers’ help. The most amazing feature of this wand is that it secures your hair when you rotate the curling wand. This gives consistent curls in size.

This wand helps you in giving you the even-sized curls. The only thing that I need you to know that you might get the clip marks or creases if you’re continuing without correcting the position. And you will see the uneven results at the end. I would like you to give some suggestions to You tubing before using these wands. You will be amazed to see the beauty of this wand once your hands get easy on this.

#2. Straight Cylindrical Barrel

This barrel doesn’t have the clip that holds the hair in place while curling. Instead of clamping, all you need to do is wrap your hair around the curler, hold it for a few seconds, and then release it. It is best for creating large waves as it allows the more area for curling that makes it easier to check the curls’ size with this styling tool. This barrel is known for its versatility. So go for this barrel if you want the consistent size in the curls. These come with a heat-protective glove for safely heated styling.

#3. Conical Wand or Tapered Barrel

It has a wider base with a narrower end; cone-shaped curling wands will create natural-looking. This barrel gives you amazing versatile big small curls. If you twist your hair around the base, you will end up getting large and voluminous curls. And if you go for the narrower tip, you will get tighter and more defined curls.

Do You Know which is the best material for Curling Iron?

It is made up of different materials, but the most popular are tourmaline, gold-plating, ceramic, Teflon, and titanium. But the materials have pros and cons that I will be going to discuss below.

The barrel is the most significant part of any curling product. Hence, choosing the right barrel with the right material is a tricky job. So choosing the right material helps you in giving amazing curls without damaging your hair.


Suppose you want to curl your hair without excessive heat, then you should go for this. Tourmaline is used for coating the solid ceramic plates. It is used over the curling iron to flatten the surface and help to trap the dampness. The curling iron that has tourmaline coating helps in evenly distributing the heat through the hair. Evenly distribution eliminates the chances of getting burnt while styling. I highly recommend using this if you hate the excessive heat during curling or straightening, then should go with tourmaline.


Ceramic is a non-mental material that is known for its evenly and consistent dispersion of heat. So this helps you to get long-lasting results.  Secondly, it is gentler than metal base curlers on dealing with your every type of hair. And it is ideal for damaged and delicate hair. Before buying, you need to understand that curlers with ceramic wands and ceramic coating must be handled carefully. As the material is brittle due to the high conduction of heat that makes it more prone to cracking. It is quite expensive, comparatively, but it is a boon to anyone who wants gentle and light curler.


If you have a good budget, you can go or this, But I want to tell you that the above-discussed material is better than this one. So don’t let fool yourself merely by appearance.  However, gold is good for your hair. The particles that are presented in gold keep your hair nourished. If we compare gold-plated curling iron with other materials, gold barrels give you long-lasting results without much damage.


Titanium is the lightest material; it heats up very fast as it absorbs the heat quickly. It is ideal for the ones who have thick hair and coarse hair. It makes the thick hair smooth and silky. Beware who have thin hair as it soaks up moisture from your hair and leaves it lifeless and dry. If you are a first time user of titanium curling iron then, you should be very careful while using it heats up very quickly so it can be easy to damage your hair.


I will never suggest you go with this barrel as it may damage your hair. Chrome produces excessive heat that ends up with fried hair due to its uneven heat dispersion. However, when you know its price initially, you will be happy to hear, but I suggest you don’t go for a cheap thing. Cheap things made you suffer, and you may end looting your pocket to make the damage undone. This is something that I strongly recommend not to buy.


Well, Teflon is used for coating iron barrels. I do not consider this as it is poor in heat distribution that makes it difficult to use. It leaves you hair frizzy and dull as it sucks all the moistures from your hair. So you can’t rely on this when you come to styling your hair.


I will give five stars to the ceramic iron rod with tourmaline added.
For thick or coarse hair, a titanium-barreled road will do justice.
A Gold-plated is suitable if your pocket is allowing.
For Chrome and Teflon, a big no.

Do you know about the Heat Settings of curling iron?

Heat settings are the crux for long-lasting curls. But creating the right balance with heat setting, you can avoid the risk of hair frying. The thick and thin hair needs low heat while the thick hair needs high-intensity heat. But remember, whatever your hair type is, one should not exceed 450 degrees Fahrenheit, always apply heat protectant before commencing with the hair-styling.  

Heat setting for Curly and Thick hair: You can set the temperature ranging from 350 to 450 degrees Fahrenheit.

Thin or chemically treated hair: Never exceed the heat setting higher than 300 degrees Fahrenheit. As fine or chemically treated hair, are more prone to heat damage.

Medium-thick hair: If your hair is medium in thickness, you should go for a curling iron ranging in temperatures from 300 to 380 degrees Fahrenheit.
