How To Choose Eyelash Extensions?

Finding the ideal set of eyelash extensions can be challenging because there are so many different types and variants to choose from. If you’re seeking great eyelash extensions, there are several things to consider. When it comes to extensions, people’s preferences, eyelid shape, natural lash health, eyelash extension length, and personal preferences all come into play. It doesn’t matter if you choose classic or volume lashes; the result will be stunning either way.

How To Choose The Right Lash Extensions?

Here are some of the most critical considerations to keep in mind:

Consider the diameter of your natural lashes while choosing lash extensions. It’s essential because it won’t look natural if you don’t, which is our ultimate goal. When choosing the thickness, you should consider the design and the condition of the client’s natural lashes.

Some thicker extensions (above 0.20) may be too heavy for some people’s natural lashes. If you make the wrong decision, your extensions may lose their hold and eventually fall off.

What Size Eyelash Extensions Should I Get?

Naturally, Asians tend to have a smaller set of eyelashes compared to non-Asian groups. Clients over 50 tend to have thinner eyelashes than younger ones, so keep an eye out for this. For clients(over 50), lash extensions with a diameter of between 0.10-0.15mm (for Classic) are recommended. However, other clients with fuller natural lashes can handle 0.15-0.20mm extensions (for Classic).

To determine the appropriate thickness for your client’s natural lashes, regardless of the client’s ethnicity or age, you should always examine the client’s natural eyelashes’ health.

Compare the diameter of the natural lash to the marked thickness of your lash extensions if you are questionable about the diameter of your client’s natural lashes. You may then determine the maximum weight that the natural lashes can hold.

There isn’t a single ideal thickness, just as there isn’t a perfect length. You’ll develop a skill for recommending lash thicknesses to clients as you get to experience selecting lash extensions. Because of this, you should be able to figure out which thickness is best for a particular look.

For starters, what kind of extensions do you prefer? Both provide their specific advantages. There are two significant aspects to consider while choosing extensions.

  • If you’re looking for classic eyelashes, you’ll need to utilize a 1:1 formula. Classic is the best option for those who want to keep their lashes looking natural while adding length. Make sure you have enough natural lashes, to begin with. If your natural lashes are sparse, volume extensions could be a better option for you.
  • Volumizing lashes (sometimes referred to as Russian lashes) give the appearance of more fullness, thickness, and softness. Each natural eyelash receives two or more lash extensions. Many types depend on how many lashes are applied: 2D, 3D, and so on.

To do the Volume technique, lash specialists must figure out how many extensions to use. Each volume fan has a specific number of strands counted in terms of the number of ‘D’s in 2D, 3D, 5D, or 20D. Eyelash extension thickness vs. weight can be determined using a volume fan calculator.

To look at it another way, if 0.15mm of eyelash extension is considered a regular thickness for one natural lash, ultra-thin eyelashes like 0.03mm lash extensions can be used as 20D. 

For Volume Lash Application

0.03mm & 0.05mm Lashes Diameter Extensions

This is the most common Mega Volume style for 2D to 6D lash extension.

0.06mm & 0.07mm Lashes Diameter Extensions

This is the Russian volume 5D’s most common thickness.

For Volume & Classic Lash Application

0.10mm Lashes Diameter Extensions

Depending on the natural lash’s strength, this thickness can be utilized for Volume 2D-3D or Classic 1D on fine natural lashes.

For Classic Lash Application

0.12mm Lashes Diameter Extensions

This is for you if you want to create a more light, wispy look and feel.

0.15mm Lashes Diameter Extensions

Natural-looking thicker eyelashes can be achieved with this type of lash thickness (Classic).

0.18mm Lashes Diameter Extensions

Compared to the 0.15mm, this lash extension is a little more adventurous in terms of looks.

0.20mm Lashes Diameter Extensions

The classic extension’s second most popular thickness. Natural-looking mascara can be achieved with this lash extension’s thickness. Only thick, healthy natural lashes should be used with this product.

Very Very Thick Eyelash Extensions

0.25mm Lashes Diameter Extensions

This extension can achieve a luxurious effect, although it may be too heavy for many people’s lashes.

0.30mm Lashes Diameter Extensions

Although most people’s lashes may be too heavy for this treatment, those with healthy, strong, and thick natural lashes will get the most out of it.

Lash Extension Length Guide

Your eyelash extension length will also have to be taken into consideration. Choose a lash length near your natural eyelash lengths if you want a fuller set. If you’re looking for something light, opt for the longer ones.

What Length of Eyelash Extensions Should I Get?

The most popular eyelash extension length is between 11 and 13 millimeters. These lengths tend to be most forgiving when it comes to improving your appearance. Eyelash extension selection is something for which you should obtain formal training if you haven’t already done so. We’re here to help, as always!

Shorter extensions of 5-9mm are used for the inner corners or under lash extensions, while 9-13mm extensions are used for the bulk of the set. To make a Hybrid eyelash extension, some professionals mix longer lengths of extensions from 14mm or longer.

Naturally, many clients desire the longest lashes, but it is essential to remember that one client’s lash health should determine the length of the extension.

If the lashes are too long for your customer’s natural lash, they may fall out prematurely. You are responsible for assisting your client through this process. Choose lashes that are a little longer lash lengths for customers with droopy or hooded eyes. It’s common for them to keep their lashes hidden from view when their eyes are open.

Remember that a tighter curl will make the extension appear shorter when applying longer fake lashes, such as D or U curls. The length of your lashes should be determined by the type of curl you choose.

You can’t just pick between short, long, or in-between lashes; many factors must be considered. A set of more excellent volume lashes may not seem natural if your eyelashes are short. Add short extensions to make your lashes appear longer if your natural ones are already long. Enhance your eyelashes with extensions that don’t intrude on the natural lash lengths.

Eyelash curls such as the J curl, which has the smallest number but is less prevalent, are another option to explore. Another type of curvature can be achieved by using a B curl to generate a more subtle effect and a C curl to make it the most noticeable. For dramatic effect, go with the D curve and for hooded eyes, go with the L curve.

How To Choose The Right Curls For Lash Extension?

To properly select extensions, you must first determine the amount of curl you prefer. A quick overview of the choices you have is as follows:

  • B, C, D, and L are the basic curls.
  • The B+, C+, CC, D+, and DD are mega-volume curls.

In general, a more prominent curl is associated with a higher letter. The only exception to this rule is the L curl. As if you’d used your lash curler a little more than usual, L curls have an unusual shape that stretches upward and outwards more than regular curls. As a result, L curls are ideal for individuals with naturally sleepy eyes.


You’ll need to consider the cost if you’re on a tight budget. Once you know how much you have to spend or want to invest in the products, you can choose the best alternative for your needs.

Color Variation Of Eyelash Extension

Make your eyelashes stand out with a splash of color by using colored eyelash trays. Pink, purple, and blue lash extensions are popular since they’re a fun alternative to natural eyelashes.

What Are The Different Type Of Eyelash Extension Curls?

I, J, Or B Curls (Subtle Lash Curls)

I Curl Lashes

I curl extensions are a less well-known curl, but they can be utilized by male clients who want to increase the thickness of their lashes but don’t necessarily want them curled.

J Curl Lashes

The J curl is the most natural-looking curl kind. These are best suited for clients with straight or upward-facing lashes. The eyes will appear smaller and heavier if you curl your natural lashes in a J shape.

B Curl Lashes

If you have naturally straight lashes, you may want to consider a B curl rather than a J curl. This type of eyelash curl is ideal for those with straight or upward-facing eyelashes, as it has more curl than the J-curl. Inner corner lashes can also benefit from a B curl.

Soft, natural-looking curls are the hallmark of B curl lashes, also known for their outstanding retention.

C, D, Or U Curls (Dramatic Curls)

C Curl Lashes

For clients with a slight curl in their eyelashes, the C curl is the best option for creating a more open look.

The C curl is one of the iconic styles in the world. A C curl can be employed for individuals with mildly drooping lashes to achieve a satisfying lift. It will create a doll-eye look if applied to clients with lashes close to a horizontal angle.

On the other hand, D curl is recommended for those with lashes slanted a lot to the bottom.

D Curl Lashes (or CC curl)

D curl is quite similar to C curl, although it’s slightly more curly. Clients with naturally curled lashes who want to make a dramatic entrance can consider getting them. The curled appearance of these lashes serves to brighten and open up the eyes.

If applied to clients with naturally curly lashes or highly hooded eyelids, the dramatic upward curl of these extensions may irritate their eyes. Customers with naturally curled lashes that fall downward are more suited to the D curl.

One of the curliest curls may not hold up as well as straight curls, but it can add drama and open up the eye for those with naturally drooping lashes.

U Curl Lashes (or DD Curls)

The curliest lash extension is the U curl .’s These lashes are best suited for clients with drooping lashes who desire doll-like lashes. There will be a visible curled look with these lashes. 

Because of the dramatic upward curl of the D curl, the extensions may prick clients’ eyelids with naturally upward-angled lashes or deeply hooded lids. As a result, the U curl is better suited to clients with naturally curled lashes than straight lashes.

M, L, Or L+ Curls (Lift-Up Curls)

M Curl Lashes

Unlike J curl, M curl doesn’t have the same impact. The flat base has a little surface area and a dramatic curvature above. Natural lashes with a downward slope will benefit from the M curl’s lifting effect. You may create a wide-eyed look with the dramatic up angle of the lash lift.

Natural lashes with an upward angle are not suitable for M curl.

L Curl And L+ Curl Lashes

Curls with flat bases are known as L and L+ curls. Because the base is flat, you can give your customer the most incredible eyelid lift. L and L+ curls were also produced for consumers with droopy eyelids, hooded eyelids, and deep-set eyes to create a wide-eyed impression. The curvature of L+ is a tad more pronounced than that of L.

These are the best lash extensions in terms of appearance. However, these lashes look heavy and ugly when put on lower-angle lashes because of their large flat base. 

EZ Curls (Better-Bonding Curls)

EZ Curl Lashes

EZ Lash’s base curl is more angular than classic extension lashes. As a result, EZ lash offers a larger surface area for extensions to adhere to, making it easier for new lash artists to get started.

Curling lashes with EZ provide better hold because of the broader adhesive surface. On the other hand, their long flat base will appear heavy and ugly when applied to downward-angle eyelashes.

How To Choose The Right Eyelash Extension By Considering Your Eye Shape?

If you are a lash artist, you know that no two customers are the same. As a lash artist, you will see clients with various eye shapes. It’s also possible that some of your customers have more than one type of eye shape. 

Before you begin lashing a client, it is essential to examine their eye structure by looking at the shape of their eyes and where they are located in their holes. After doing so, you will better understand the customer’s eye shape and the appropriate style to recommend.

The monolids, almond eyes, round eyes, upturned eyes, downturned eyes, and hooded eyes are the six most prevalent types of eye shapes. Round eyes are the most common type of eye shape.

Monolids Eyes

Your customer has monolids if the lids do not have a crease in the middle of either eye.

  • Cat, doll, or squirrel is the recommended styling for them.
  • It is best to use a curl with a flatter base, such as an M or an L, for lashes that naturally point downward. A Cat, Doll, or Squirrel style can likewise be used with a CC or D if nothing else is specified.

If the person you are working with does have a crease, then their eye shape will be one of the following:

Round Eyes

If your customer has a crease that can be seen on their upper eyelid and the iris of their eye is surrounded by a very slight amount of white that separates it from the top and bottom eyelid, your customer has a round eye shape.

  • The cat and squirrel styling is recommended for round eyes.
  • When creating a slimming impression, use shorter lengths curled in a gentler curl and extend towards the outer corners of the eye.

Almond Eyes

If your customer has a crease that can be seen on their upper eyelid, in contrast to people who have round eyes, their iris touches both the bottom and top of their eyelid, and you have a client with an almond eye shape.

  • Any type of eyelash can look good on almond-shaped eyes.
  • The C Curl is a helpful styling technique that gives the appearance of additional lift and curls. The CC Curl is a popular curl that gives a more stunning appearance but can still be worn daily.

Downturned Eyes

It is simple to spot eyes that are cast downward. This is characterized by a downward tilt of the outer corners of the eyes. If unsure, try picturing a line drawn horizontally across the client’s eye. They are referred to as having downturned eyes when the outer corners turn down below the line.

  • This eye shape looks best with squirrel lashes. Use an open or lifting style to help draw attention away from the downturned outer corners.
  • If the eyelashes are straight, you should use a strong curl. Put the bulk of your effort into the area you wish to make longer or lift.

Upturned Eyes

The opposite of downturned is this position. Do the eyes of your client’s periphery turn slightly higher when they look at you? Apply the same strategy you did while screening for eyes that were turned downward. Your customer has upturned eyes if the outer corners of their eye curve upwards above the line.

  • Use a Cat Eye or Squirrel style, depending on the aesthetic you want in the end.
  • Use a gentle curl, giving more length to the outside corners and keeping the curls closer together in the center.

Hooded Eyes

As we age, our skin loses its flexibility, resulting in hooded eyes. This is a regular phenomenon. Your customers have hooded eyes if they have a crease that can’t be seen because a flap of skin covers it. This crease makes their eyes look smaller than they are.

  • Squirrel styling is recommended for the hooded eyes.
  • To remove the curls from behind the lid and bring them to the surface, use tight curls of sufficient length. When giving customers the appearance of a gorgeous lash lift, an L curl is the best option for those with hooded lids or lashes that point downward. An excellent suggestion is to tape the lid back to get it as close to the lash line as possible.

At this point, you ought to understand how to choose eyelash extensions lengths, thicknesses, and curls. We know this is a plethora of information, particularly since you are just starting, and we apologize for that.
