Can You Curl Eyelash Extensions? Depends How You Do It

Can you curl eyelash extensions? Well, for the majority of lash extension enthusiasts, the answer would be simply: why would you want to?

When you’re getting lash extensions, you expect them to be perfect. Ideally, they would offer the perfect length, volume, and curl.

And that is something you can achieve, if you are able to successfully communicate your wishes to your technician. But what if it’s the first time you’re getting them, or you just wish you’d gone for more curl?

Can you curl your eyelash extensions? And what is the best way to do it? Let’s take a look at some of the methods.

Can You Curl Eyelash Extensions?

First, let’s address whether or not you can even curl extensions. Look, you can do it, technically, but you should avoid it. It’s not the best for them, and because they’re glued onto your real lashes and they can be so fragile, you generally want to mess with them as little as possible.

That being said, it can be done, you just have to do it in very specific ways and stay away from other methods that can really damage them extensively. 

Can You Get A Lash Perm On Your Extensions?

Let’s get this one out of the way – lash perming is a treatment you can get for your natural lashes and yes, it’s just like perming your hair. Your natural lashes are curled using a special shape and a chemical perming solution is used to fix them into place. 

However, because of the chemical nature of this procedure, you cannot – we repeat, cannot – do this on eyelash extensions. They’re not always made from human hair, and they are glued on, which does not play nice with the chemical perming solution.

Can You Use A Traditional Lash Curler on Extensions?

This is where it gets tricky – traditional lash curlers are typically much too harsh on extensions.

But what if you use one of the best eyelash curlers, you ask? No matter how expensive and high-quality they are, the mechanical action used to curl the lashes is a bit too harsh, and there is always a risk that you might accidentally pull out some lashes or extensions.

You can maybe (we don’t recommend it) use a traditional pair of curlers if you do it very gently, apply hardly any pressure at all, and do it just as a quick squeeze, so you won’t accidentally displace any of the lashes and never ever (ever ever ever) do it while wearing mascara.

What Is The Best Way To Curl Lash Extensions?

If you must curl your extensions, it’s in your best interest to use a method that is the least damaging to your lashes, and that is also going to be the most effective.

In this case, that is going to be a heated eyelash curler. Yes, it’s more expensive than the $2 mechanical curler you buy at Sally’s, but at least this one won’t cut your eyelashes in half. We’re not saying it happened to us, but…be careful.

The heated eyelash curler is much more gentle on the extensions, because there is no pressing action, no pressure, and no metal bits squeezing or pulling your lashes.

A heated eyelash curler is usually plastic, and it looks a bit like a curved stick. It heats up, and you brush your eyelashes from underneath like you would with a mascara wand.

Hold it in place for a few seconds, and voila – curled lashes, in a much gentler way that will help the curl last longer. 

Why Is A Heated Eyelash Curler Better For Lash Extensions?

First of all, as we said, there is no scary metal contraption that vaguely resembles a medieval torture device. That already makes it a winner, in our book.

But how does it work, and why is it better than the regular curler, even on natural lashes? 

Well, you know how you curl your hair with a heated curler or straightening iron? It’s the exact same thing, but for your lashes.

The tool is heated and shapes the lashes, and then when they cool off, the shape is “fixed” in place, just like with hot rollers or curling iron.

That means that this will hold the curl for much longer than just bending them with the mechanical eyelash curler does. 

A word of caution: If you do use a heated eyelash curler on eyelash extensions, make sure not to get too close to the root. Your extensions are fixed with glue, and this tool is hot, which may interfere with the glue.

How To Choose The Right Curl For Eyelash Extensions?

There are multiple types of eye shapes and each has a different feature. You can not treat them equally. A little effort is made to select the right curler for eyelash extension.

Each eye shape fits a specific extension that has appropriate thickness and length. If you use random extension then it will affect the real eyelashes. Due to more thickness, you will feel heavy. Also, with a large length, there are more chances that your real lashes will fall.

The best eyelash extension is the one who has perfect thickness and length according to real lashes. There are different types of extensions and each demands separate curlers. Have a look at all types of curls so that you can easily choose the one for you.

7. LC-Curl:

How To Choose The Right Length And Diameter Eyelash Extensions?

After you have read about all the curls it’s the right time to know about how to select the right length and diameter.

Because natural lashes are too sensitive. If you choose too thick and long extension then it can damage the natural eyelashes.

You have to choose the right length which is not greater than 2 to 3mm than the natural eyelashes. This weight is enough that your natural lashes can bear easily. To balance the weight right diameter selection is important. 

The available diameter of lashes in the market ranges from 0.03mm to 0.30mm. Professional lash artists prefer to use lash extensions under 0.15mm. 

There was a time when people even professionals use 0.25mm of lash extension. But now they stop at 0.15mm. The reason is this, now the thickness is increased. 

Today 0.15mm is equal to the past 0.25mm diameter.

Also, the product quality is changed. If you choose a heavy diameter or long lash extension then it will surely affect your natural eyelashes. They can fall when in a premature stage. 

It is said that a long lash extension looks wispier. While on the other hand, short lash extensions look more dense and full. But as a professional always know your clients thought before applying products.

Choosing The Right Lashes For Different Eye Shapes:Lashes For Different Eye Shapes

Now: it’s the showtime where you display your skills. You have read about different types of curls and their length and diameter. In this step, you put this information into practice. 

It is a common thought that whats looks good on one person does not suit the other one. Because they have separate features and expressions.

Put the right eyelash extension according to the right eye shape.

1. Almond Eyes:

It is the most common eye shape where you can try anything it looks good. Almond eyes can bear any length and thickness. So do not worry put what you think is right.

2. Monolid:

This eye shape required thick lashes to gives a unique look. To do the inner and outer corners L-curls play an important role.

3. Wide Set Eyes:

You can use any curler on wide-set eyes. But the shorter in the corners and longer in the center creates an amazing look.

4. Close Set Eyes:

You can use two types of curls in it. One is D-curl and the other is CC-curl. If you keep a longer length on the outer corner then it will be amazing. D-curl is used for the lid and CC- curl covers the outer corners. 

5. Downturned Eyes:

They need a lot of corner lift. It is the exact opposite of close-set eyes. You can use a CC curl for the eyelid and a D curl for the outer corners. These curls will make a great eye lift appearance.

6. Hooded or Deep Set Eyes:

You can use C-curl on Deep Set eyes. They need a softer curl with longer lengths eyelash.

7. Prominent Eyes:

D curl is the only best option for prominent eyes.

Every type of eye has different features. Sometimes, as a professional artist, you may encounter customers with different eye shapes. It is possible that you get confused but do not need to worry.

Keep all the steps in the sequence so that you do not get confused while curling an eyelash. 


You want to avoid that, so go for a less extreme curl, holding the tool towards the middle of the lash, instead of right up against the root.

So, if you simply must have ultra-curled extensions, remember this: the mechanical curler is a no-go, and use the heated curler with maximum care!
