How To Shop For The Perfect Long Hair Curler

In shopping for your curler, there are a few factors that you need to consider. It’s best if you get one that’s ideal for the length of your hair. To do that, you need to ask yourself a couple of questions:

1. What size curling iron do I need for long hair?

The first thing you need to look at is exactly how long your hair is. Different irons vary in size, and this can really be seen when you look at the barrel. Some barrels would be a typical length, while some would be one or two inches longer. This is because a curling iron for extra long hair would also need to be extra long in length. Be sure to watch out for this feature as you shop for yours.

2. What size of curls am I after?

The question “What is the best size curling iron for long hair?” should not just pertain to the barrel length but also its diameter. You can have a really long barrel but if it’s small in diameter, chances are, all you’ll get are tight spirals and curls.

When looking at different barrel sizes, remember the general rule: the bigger the barrel size, the bigger the curlsNow if you have a large barrel curling iron, you can use it for loose and beachy waves. You have to keep the length of your hair in mind and ask yourself what kind of curls you’re after. For long hair, most people prefer loose waves, but you might also go for tighter curls. It’s really up to you.

3. Aside from being long, how else can I describe my hair?

Looking at the curling iron size for long hair is not the only thing you need to consider. You also have to take a look at how else you can describe your hair, aside from long. Is it fine? Is it thick? Is it frizzy?

The reason for this is that the best curling iron for long fine hair may not necessarily be a good curling iron for long thick hair. It’s also important to look at hair thickness. If you have fine and delicate hair, it’s best if you get one that has lower temperatures available. On the other hand, if your hair is really long and thick, it should have temperatures that go as high as 400 degrees Fahrenheit and hotter.

Now that you know what kind of curler for long hair is best, you can start looking at the many options out there. The factors that you should consider include: size, temperature, and available technology, but getting a curling iron from a credible brand is also important.

Features To Consider When Choosing The Best Curling Iron For Long Hair

Barrel Length

The barrel length of your curling iron is a huge factor because it determines just how long you will have to spend curling your hair. Shorter barrels would generally require more time and effort  than longer-barreled irons. 

Curl type

Curling irons are available  in different shapes and sizes and you should make your choice based on the length and texture of your hair, as well as the type of curl you want. 

The curling iron you choose should perfectly match your hair length and thickness to ensure your curls are uniform and last all day long. 

If you want tight, defined curls, go for a smaller barrel, while those wanting looser curls can go for larger barrels. Small barrels of 0.75” and 1” in width usually curl much tighter and are more suitable for people with short to  shoulder-length hair. 

Barrels with 1.25” inches, are used for curling longer hair that may be too much for 0.75” and 1” barrels. Thicker barrels ensure your long hair is curled in half the time it would take smaller barrels. 

Hair type

Your type of hair can also fully determine the curling iron you choose to purchase. Do you have thick hair? Is your hair frizzy in nature? Does your hair often tangle? The barrel of most curling irons are made to counter hair problems like these, so be sure to know your requirements before buying.

People with thick hair will not only need long barrel irons, but those that can heat above 420° to enable them curl their hair properly. 

Longer barrels handle resistance from thick hair better as they allow you to generate more force while curling while shorter barrels may not be as effective. Longer barrels with high max heat are also good if your hair tangles often as they are more effective at curling your hair and getting rid of tangles at the same time.

There are also irons with special materials to combat frizzy hair and ensure your hair remain sleek all day, every day. Nano titanium curling irons are used mostly on frizzy hair to keep them looking sleek and compact. People with thick hair should go for ceramic barrels as it is perfect for curling stubborn hair. 


If you wish to purchase curling irons with special materials and technology like the ceramic curling irons and nanotech irons, you should know that they are costlier than your regular curling iron. 

While you may find some irons with fantastic features in the regular price range, special irons with extra features will usually cost you more, which is why budget is also an important factor to consider when purchasing a curling iron for long hair. There are some fantastic affordable  options for people with long hair, but as it usually is, the best are often the costliest.

Curling Wand Vs Curling Iron For Long Hair

Once you’ve picked the curling iron best suited for your hair type, the next question you should ask yourself is how to use it. It’s not only enough to have the right curling iron for very long thick hair, you must understand how to use it properly.

How to use a curling iron on long hair

How to curl long hair with a curling iron

Below are some tips:

1. Preparation is key.

Making sure that your hair is prepared for styling is just as important as the styling process itself. This is because styling can do a lot of damage if you’re not careful, especially if heat is involved. Now when it comes to curling irons, heat is always involved. You’re basically using a heated barrel to transform your straight hair to beautiful curls, so you should make sure your hair is protected enough.

To give your hair a little protection, there are several products that you can use. There are heat protectant sprays and serums that guard your cuticle against too much damage. You have to make sure that you apply these protectants before you apply the heat. It’s also important to keep your hair as healthy as possible. Maintaining the health of your hair through regular conditioning and care is important, especially if you style it often.

2. Don’t do it all in one go.

When styling, it’s always best to work in smaller sections. This is especially true if you have long hair. The length of your hair can get overwhelming and you shouldn’t feel pressured to style all of it in one go. Before using the curling iron, it’s best if you divide your hair into smaller sections and use clips or clamps to keep each section together.

With your curling iron in one hand and the other free to be used to twist your hair, start with the lower sections (near the nape) and work your way layer per layer to the top. It’s best to work this way so that the curls are well defined per section.

3. Pick the heat setting that’s right for your hair.

When curling your hair, you have to make sure that you’re using the right heat setting. If your hair is long and thick, the high heat settings will work best. Going for temperatures of at least 400 degrees will ensure that your hair is styled properly no matter how thick it is.

If you have delicate hair on the other hand, you should only go for the low heat settings and try not to go beyond 300 degrees. Going for temperatures higher than 300 might cause damage on your hair, and this is the last thing you want to happen especially if it’s thin and delicate.

When it comes to heat, it’s the thickness of your hair that you should look at and not the length. It also helps if your curling iron is equipped with technology that will make it heat up faster than normal, because the shorter time you apply the heat, the better.

When you twist your hair, you should also be aware of the kind of curls you want. If you want tight curls, you’ll need to wrap it around a smaller barrel many times. If loose waves are what you’re after, you have to increase the diameter or distance between the curls.
