What Are Eyelash Extensions?

Lash extensions refer to artificial or natural fibers that are affixed to natural lashes to add thickness, length, and curl. It can open up your eyes and brighten it.

Lash extensions are applied by licensed professionals in a span of an hour or two, sometimes even more. Your natural eyelashes range from 90 to 120 per eye. That’s why lash techs may add 60 extensions per eye, or double of that number, based on the style you want. These are different from traditional strip lashes or clusters as lash extensions are customized to the shape of the eye and texture of natural lashes of every client.

Types of Lash Extensions

Here’s a complete list of different types of fake lashes from their construction to size, and more to choose from:

Material

There are natural and synthetic options when it comes to lash extensions. Natural fibers include mink, sable, fox fur, and silk fibers. Artificial fibers refer to cruelty-free synthetic lash extensions (also called acrylic lashes) that are made from a thermoplastic fiber called PBT.

Length

You can get fake lashes in short lengths of 5 mm to 8 mm, moderate lengths of 9 mm to 12 mm, long lengths of 13 mm to 16 mm, and extra-long options of up to 20 mm. Currently, the most common lengths of lash extensions range from 5 mm to 16 mm.

Curl

Based on the curvature of the lash extensions, there are different curls available in the world of extensions such as I, J, B, C, D, CC, DD, U, L, and M. There are also curls with enhanced lifts marked by the ‘+’ sign such as L+, B+, C+, and D+. Amongst these, I and J are common straight lashes with/without a slight curve, unlike the other curly alternatives.

Diameter

In the world of fake eyelashes, the thickness of extensions is calculated in millimeters and selected to complement the thickness of natural lashes without feeling too heavy or droopy. Lash techs typically use sizes that stretch from 0.03, 0.05, 0.07, 0.10, 0.12, and 0.15 mm but more uncommon diameters such as 0.18, 0.20, 0.23, 0.25, and 0.30 mm are also available.

Color

While extensions made from natural fibers are available in colors like black or brown, artificial lash extensions feature exceptional hues like red, pink, green, blue, pink, orange, purple, white, gold, silver, ombre, blonde, and more.

History Of Eyelash Extensions

Lash extensions are used by a good majority of men and women with thin, sparse, and short lashes to enhance their looks. Where did lash extensions come from and who invented eyelash extensions?

A German hair specialist in the U.K called Charles Nessler (aka Karl Nessler) is commonly referred to the inventor of eyelash extensions. He began selling fake eyelashes via his salon in London one year after registering the patent- ‘A New or Improved Method of and Means for the Manufacture of Artificial Eyebrows, Eyelashes and the like’.

The eyelash extension history is rich. How far has it evolved? Let’s find out all about the origin of this cosmetic procedure that has seen significant changes over the years.

1800s: World’s First Eyelash Extensions

The first eyelash extensions were made of human hair in the 19th century and glued to the eyelids. Although they fell off after a few days of irritation^[1], it’s hard to imagine the allergic reactions that must’ve followed due to their widespread use.

1899: Eyelash Extension Operations

If you’re already wearing eyelash extensions, you might know how convenient getting them is. What’s more, most of our clients find it so relaxing that they doze off during sessions. But the same wasn’t the case a few centuries ago.

Let me warn you, it’s going to be a little graphic.

Around the end of the 19th century, several cosmetic specialists began offering implants for eyelash extensions. According to Dundee Courier dated 6 July 1899, specialists did such an operation by threading a needle with hair taken from the head of the person to be operated on. Next, the lower lid was thoroughly cleaned and dabbed with liquid cocaine to limit the pain.^[2]

Hair was then stitched onto the eyelids, followed by cutting and trimming of fibers. Eyes were then bandaged for a day after curling the lashes with silver tongs.

The good news was most of these transplants would then develop roots on the lash line, but several others would fall out.

The Early 1900s: False Lashes Patented

A German hair specialist in the U.K called Charles Nessler began selling fake eyelashes via his salon in London one year after registering the patent- ‘A New or Improved Method of and Means for the Manufacture of Artificial Eyebrows, Eyelashes and the like’.^[3]

This was followed by the first-ever U.S patent on strip lashes by Anna Taylor in 1911 where she attached a fabric strip with hair fibers to create fake lashes.

1916: Hollywood Debut

Although lash extensions were finally getting into the mainstream market, it wasn’t until the Hollywood movie ‘Intolerance’ that it really became popular.

As the director of the movie D.W Griffith wanted his actress to have eyelashes that brushed against her cheeks, he instructed his wigmaker to make false eyelashes for his heroine- Seena Owen.
While Ms. Owen suffered from severe allergic reactions afterward, the style caught on so much that 20 million pairs of false lashes were sold annually in the 1930s.

1940: The First False Eyelash Company Is Born

Back in 1947, the Aylott brothers who worked in the film industry decided to establish their own brand called Eylure. They began the world’s first large-scale production of false lashes by the ’60s in Cwmbran, a town in Wales.^[4]

Eylure is also the same lashes that created the iconic look of Elizabeth Taylor’s Cleopatra in 1963. Thereafter, fake lashes became such a rage that many other companies like Revlon and Max Factor launched false eyelashes commercially while celebrities like Marilyn Monroe, Twiggy, and Rita Hayworth preached it as an essential beauty tool.

The 2000s: Advent Of Artificial Lash Extensions

Combining available knowledge from the past and present on lash enhancements at the time, eyelash extensions were created and glued to natural eyelashes somewhere around Japan and Korea during the early 21st century. These were lightweight, safe, comfortable, custom-made, and long-lasting, unlike the earlier versions.

However, lash extensions hit the limelight when celebrities openly started giving credit to fake lashes for their gorgeous eyes. The Business Insider article notes that Jennifer Lopez wore lashes made from red fox fur in 2001 to the Academy Awards and Madonna in 2004 wore mink and diamond lashes on her tour.

2008: Eyelash Extension Manufacturing In Large Scale

According to Wiki sources, it was in 2008 that eyelash extensions were first manufactured on a large scale by a Korean beauty business called Aesthetic Korea Co. Ltd. In the past decade, many eyelash extension manufacturers have popped up all around China, Vietnam, Thailand, India, and other Asian countries owing to the expensive nature of Korean fake lashes.

2021: The Eyelash Extensions Industry Up Till Now

Over the last decade, the industry has come back to life with innovative techniques and booming sales.

From the year 2017 to 2018, the eyelash extensions industry was taken by such a storm that search engines recorded a 152% increase for the keyword ‘eyelashes’^[5] besides selling more than $270 million lash extensions^[6] at the same time. According to ABC News, eyelash extensions are set to become a $1.5 Billion industry in the next couple of years.^[7]

Another favorable upgrade has to do with the lash adhesive. The cyanoacrylate glue that usually took 24 to 48 hours to cure completely is now reduced to just four hours.

In 2014 the owner of One Two Cosmetics invented magnetic lash extensions, which is quoted as the latest innovation in the industry by The New York Times. Glitter lashes followed and today you can find lashes with more colors than the rainbow. Unlike a decade ago, men are also taking into eyelash extensions enthusiastically today.

While COVID did affect the industry of eyelash extension just like any other industry, it’s not winding down anytime soon because eyes are now all the more important, thanks to face masks covering up the lips.

Recently a brand called Luum was featured on TechCrunch discussing their high-precision robots capable of replacing lash artists in the salon to increase the market size into tens and hundreds of billions.^[8]

In short, eyelash extensions aren’t a fad anymore, it’s already a standard of modern beauty.

Are Eyelash Extensions Good Or Bad For Your Lashes?

Just like electricity can both be a boon and a bane based on how you use it, eyelash extensions can make you drop-dead-gorgeous or sick.

While lash extensions are safer and painless than ever now, aftercare and a poorly done job often lead to allergies, infections, clumping of lashes, sparsing, and loss of natural lashes.

For instance, if the lash tech selects extensions that are heavier than your natural lashes, they will end up drooping or falling off with added weight. Alternatively, a poorly attached extension can lead to corneal abrasion. Techs can also stick extensions to multiple natural lashes, preventing their growth and movement, leading to botched eyelash jobs.

Moreover, getting lash extensions also translates to lesser eye makeup because who needs mascara and the eye pencil when you have wispy lashes. The right size, weight, and curl of lash extensions can even support natural lashes to grow comfortably. While most states in the United States mandates licensed experts to perform lash extension services, not every state is bound by it.

Hence, it’s crucial you select a reputable studio to help you find the right extension and a well-experienced artist to do the treatment perfectly.

False Lash Alternatives: Strip Lashes Vs Cluster Lashes Vs Magnetic Lashes Vs Individual Eyelash Extensions

There are many different types of fake lashes available in the market today. Some may last a day and others even a month. That’s why it’s important to have a clear idea of what’s what by comparing the features and traits of different fake lashes before you commit to any.

Strip Lashes

When natural or artificial fibers are attached to a band of fabric so as to affix it atop the lash line, against the skin, in a single piece, it’s called a strip lash. These fake lashes typically last a day and may cause skin or lash damage if you sleep wearing them. Overuse of strip lashes can lead to thinning out of your natural lashes.

Being affixed to the lash line in one piece, it’s heavier than eyelash extensions. That’s why the weight of the fabric band and glue can overburden natural lashes, causing them to fall out.

Cluster Lashes

Small parts of strip lashes in a bunch are attached to several lashes at once rather than single lashes to create cluster lashes. The same is why it can feel heavy when opening or closing eyes. Moreover, too much glue is used for the application, which can cause your natural lashes to fall out excessively.

While clients go for cluster lashes because they’re cheap, clusters can even lead to permanent lash loss. On top of it, these are often glued to the eyelid, causing skin irritation too.

Magnetic Lashes

A reusable kind of false eyelashes that don’t use any glue, magnetic lashes are quite a novelty at the moment. These use magnetism to enhance your lashes either with a magnetic eyeliner or by using two magnetic lash strips above and below natural lashes.

While magnetism sounds great, it can damage the lashes by causing them to tear up when used incorrectly. They can even push your lashes to grow in the wrong direction.^[9] Moreover, it’s not much better than strip lashes because magnetic fake lashes don’t last over 10 hours.

Individual Eyelash Extensions

Synthetic and natural fibers that are applied one by one or with handmade fans to your natural lashes are individual lash extensions. These are costly and time-consuming, but the safest best option for your natural lashes.

Individual lash extensions are carefully applied by a licensed lash tech at the salon to the lashes and not the eyelids. This type of false lashes lasts two to three weeks because they are applied directly on your natural lashes and therefore will need to be replaced as your natural lashes fall-off naturally with the growth cycle.

Eyelash Extensions: Classic Vs Hybrid Vs Volume

Confused about the industry jargon? Find out the differences between these three lash extension techniques used by lash techs because you’ll have to talk about them later on when deciding on the right style for you.

Classic

Created for giving a natural look to the eye, this technique uses a 1:1 combination of individual lash extensions to natural lashes. It takes 1.5 to 2 hours to create the complete look using different lengths, thicknesses, and curls for both eyes.

Classic lash extension sets are carefully created to match the characteristics of your natural lashes in the best way without being too long or heavy.

Volume

Volume lashes are when several lashes are affixed together to make a fresh fan that’s then added to your eyelashes to create a lush, thick, and curly set of lashes. Volume is a Russian technique where extensions are lighter than those used for classic extensions to prevent weighing down on natural lashes.

Volume and Mega volume are two distinctly different lash extension styles. The former uses 2 to 5 lash extensions per fan and the latter 6 to 16 to create a dramatic look. Compared to the classic type, volume promises higher customization.

Hybrid

A combination of classic and volume lash extension styles, hybrid is heavily customized to create unique looks. It’s popularly known as the American Volume Lashes and Kardashian Lashes too. It uses a classic lash style of one extension per natural lash mixed with handmade volume fans affixed per lash using an eyelash extension adhesive.

Most lash techs alternate between classic and volume lashes in this style based on the size, shape, and traits of the eye. Here’s a glimpse of the hybrid set from our Instagram Page.

Eyelash Extension Styles

Wondering what’s the best eyelash extensions to get? There’s no universal lash extension style that suits all types of eyes. Lash techs use different patterns of lengths, thicknesses, and curls to create varied eyelash extension styles that compliment your features. Let’s take a look at the popular styles you can choose from.

Natural

This is a lash style where the classic set is applied (sometimes mixed with the ‘volume’ technique) based on the natural appearance of your lashes.

At Divine Lashes, we add 80 lashes per eye typically to create the natural full set. If you’re interested in natural styles, check out our Instagram page for more inspiration.

Doll Eye

Considered the best for Almond shaped-eyes, the doll eye style opens up the eye with a well-defined outline. The lash tech does that by adding the longest lash extensions towards the middle of your eyes. It compliments hooded and monolid eyes perfectly too.

This style gives more focus to the center of the eye and is particularly good if you have a sharp arch to your eyebrows.

Cat Eye

One of the typical styles that is frequently requested, cat-eye is best for transforming downturned eyes although it looks good on close-set and almond eyes too. It’s created by adding long lashes to the outer eye and short ones to the inner corners. Such a style creates a look akin to the winged eyeliner.

Check out the Cat Eye style on our Instagram page to know about it more.

Natural Sweep

This is a style where drama and thickness of lash extensions come into play. Natural sweep eye shape is best for almond, hooded, downturned, and close-set eyes to balance the shape. It’s created by adding short lashes in the inner corner of the eye followed by long lashes and finally short lashes towards the outer corner of the eye.

How To Find A Good Eyelash Extension Salon?

Finding a good lash service starts by finding a licensed lash tech. Certified technicians who use safe and high-quality products are a must for getting proper eyelash extension treatment without damaging your eyes.

Much like assessing a restaurant or brand before buying from them, check out the experiences, reviews, and history of the salon and its techs before taking an appointment with them. You can request to see the before-after pictures of clients to get to know about their skills before signing up with them.

What’s The Cost Of Lash Extensions?

Many things affect the cost of eyelash extensions such as the lash technique (classic vs hybrid vs volume), the total appointment time, the experience level, lash extension material, and the location of the salon. This combined with tipping standards determines the cost of a lash treatment.

Lash extensions are no doubt one of the costly cosmetic treatments. Fashionista rounds up the cost to $150 to $200 for a classic set, $200 to $300 for volume sets, and $55 to $95 for refill sessions. A full-set often takes two to three hours and a refill session up to 1.5 hours.^[10]

Getting eyelash extensions also means making substantial changes to your cosmetic products and cleansers. At Divine Lashes, you even get a free lash shampoo with your first lash extension session.

What To Expect For Your First Eyelash Extensions Appointment?

Never got eyelash extensions done? You’re gonna love the transformation even more than a regular. What’s more, lash sessions are so relaxing you might even sleep off during the treatment. Take a look at what Refinery29 felt about her experience at our salon to get an idea of how it works.^[11]

But if you want a checklist of how to prepare for your very first lash extension session, here you go …

• Consult first: Always have a long chat with the lash tech who will work on you to relay your preferences first. This will help the technician design a custom style for you.
• Wear comfy clothes: As most lash extension treatment requires clients to lay down, it’s best to wear a comfortable attire that doesn’t restrict your body.
• Make a playlist and get the headset: If you find music relaxing, create a playlist and take your favorite headset when going for the appointment.
• Remove your makeup: Makeup products often contain oils and other conflicting components that can degrade the lash extension treatment. Remove it before going to the salon or sitting down for the final appointment.
• Disclose your allergies and do a test: Always share your seasonal allergies as well as cosmetic allergies with the lash tech before doing an allergy test to ensure you’re on the safer side.
• Be relaxed: In order to sit still for a few hours, you need to be well-rested and tension-free. Also keep in mind to avoid having excessive amounts of coffee, chocolates, and other stimulants.
• Take off your contacts: If you’re wearing any contact lenses, you’ll be asked to remove them before the appointment due to safety concerns. You can re-apply them once the lash treatment is complete.
• Turn your phone on silent: A good way to limit distractions is by placing your cell phone on silent mode. You can also let your friends, family, or necessary persons know that you’ll be unavailable for the next couple of hours.
• Go to the loo before you start: To make yourself most relaxed over the next couple of hours, it’s good to empty your bladder before you sit down for the session.
• Understand the procedure: Ask your lash tech about the procedure and they’ll explain when they will apply gel pads, tapes, extensions, and what you need to do during the time. Typically, you’ll be asked to keep your eyes shut for the next couple of hours.
• Take before-after pictures: Don’t forget to snap a few before-after pics of your lashes too!

How Long Do Eyelash Extensions Last?

Eyelash extensions typically last two to four weeks and sometimes more based on your body. The total lash growth cycle of natural lashes is approximately 90 days. It first grows thicker, maxes out in length, then stops growing, and finally sheds. This also means every eyelash is growing at its own rate. Hence, the refill schedule also differs from person to person.

Lash extensions aren’t like strip lashes that last a day because they are applied lash-by-lash. That’s also the same reason why lash extensions don’t come off all at once. It sheds with the natural hair over the span of three to six weeks. Some may shed early, and other eyelashes late.

Based on 1100 clients who come to Divine Lashes, 60.1% come in for a refill in three weeks, 20.6% every two weeks, 16.7% every four weeks, and 2.7% after four weeks.

How To Maintain Your Lash Extensions?

Apart from avoiding water for four hours after getting your extensions done, there are many aftercare techniques to extend the life of lash extensions nowadays.

• Cleaning: First off, you need to clean your eyelashes one to two times every day with a compatible cleanser. Keep in mind to avoid water pressure directly on lashes when showering with extensions.
• Brushing: Combing your dry lashes will prevent them from tangling besides cleaning debris and avoiding clumps. The best way is to brush them on a daily basis.
• Curling: Never use a mechanical curler on your lash extensions as it can pull and snag on them, leading to premature falling out.
• Keep off the eyes: It’s best to avoid rubbing or scrubbing your eyes harshly as it can also cause extensions to shed early.
• Refill: Going for a refill at the right time, typically every two to three weeks to reduce the cost of doing a full set and maintaining a beautiful lash line.
• Hairdryer: Never use the hairdryer on the hot setting and always go for the cool setting. That being said, you could also let them air dry on their own before you brush them.
• Avoid heat, oil, and salt: From swimming in the ocean to avoiding sauna, and using cosmetic products with oil around the eye such as waterproof eyeliner and mascara, there are many ways to maximize the retention of lash extensions.
• Sleeping etiquettes: When sleeping with eyelash extensions, you can start sleeping on your back or side besides replacing your cotton pillow covers with a soft fabric like silk or satin to prevent lashes from snagging on them.
