Classic Lash Extensions | A Must-Have For Your Beauty Routine

Classic lash extensions are a popular beauty treatment involving attaching synthetic lashes to each of your natural lashes using a semi-permanent adhesive. The goal is to create the appearance of longer, fuller lashes without the need for mascara or other makeup.

It is an excellent option for those who want a more natural-looking enhancement to their lashes, as they typically use a single extension per natural lash. The process can take one to two hours, depending on the desired look and the number of lashes applied. With proper care and maintenance, classic lash extensions can last several weeks before needing a touch-up.

What Are Classic Eyelash Extensions?

Classic eyelash extensions are a type of cosmetic enhancement for natural eyelashes. Additionally, this technique involves attaching a single synthetic extension to each of your natural lashes using a medical-grade adhesive. The extension is applied to the natural lash, close to the lash line, giving the illusion of longer and thicker lashes. Moreover, classic eyelash extensions are customizable to the desired length, thickness, and curl of the individual’s natural lashes.

Types Of Classic Eyelash Extensions

Several classic eyelash extensions vary in length, thickness, and curl. Here are some of the most common types:


Classic lash extensions are available in various lengths, typically ranging from 5mm to 15mm. Moreover, the extensions’ size varies within a single set, with shorter extensions applied to the inner corner lashes and longer extensions to the rest of the lash line. Therefore, it is crucial to choose the appropriate length to achieve the desired look and carefully consider the extensions’ weight to prevent discomfort and potential damage to your natural lashes.

Among the available options, the most popular lengths for classic lash extensions usually fall within the 9mm to 13mm range. However, to ensure the extensions are suitable for your natural lashes, they should not exceed 20% of the length. By considering the appropriate size and weight of the extensions, you can create a natural look and comfortable look that perfectly complements your natural lashes.

  1. Short classic lash extensions range from 5mm to 8mm and are usually applied to the inner corners of the eyes.
  2. The medium length of classic lash extensions is the most commonly applied, ranging from 9mm to 12mm.
  3. Long classic lash extensions are available in lengths of 13mm to 14mm.
  4. Extra-long classic lash extensions, ranging from 15mm and above, are typically used for hybrid lashes and can vary in length depending on the desired look.


Classic eyelash extensions come in different thicknesses, typically from 0.03mm to 0.25mm. The most popular thickness for classic lashes is 0.15mm, which gives a more natural appearance to the lashes. For those who prefer a bolder and more dramatic look, 0.20mm lash extensions can be a good choice. However, it is crucial to note that only individuals with exceptionally robust and healthy natural lashes should opt for anything thicker than 0.15mm. Therefore, choosing the right thickness of classic eyelash extensions is essential based on your natural lash health and the desired look.


In addition to typical round-based extensions, there are also flat lashes that can be used in classic lash extension sets. Due to their better adherence to natural lashes, flat classic eyelash extensions are becoming increasingly popular. This is due to the wider oval-shaped base, which differs from the base of round-shaped lashes. Flat lashes, also known as elliptical or cashmere lashes, are lighter than classic lashes, require less glue, and last longer. Using flat lashes can result in darker and more dramatic classic eyelash extension looks.

Curl Type

Classic eyelash extensions come in different curls, each identified by a letter that describes its appearance. These include:

  1. I curl, ideal for clients with straight lashes, including males.
  2. J curl slightly lifts straight lashes and gives them a more pronounced curl.
  3. B curl, which looks natural and is often used for the inner corners of the eyes, provides a subtle eyelash curler effect.
  4. The most popular curl, the C curl, is perfect for achieving a lifted lash style that opens up the eyes.
  5. D curl, which is glamorous and dramatic, is another popular option.
  6. L-shaped lashes with a sharp upward curl are ideal for individuals with hooded eyes.

How Long Do Classic Eyelash Extensions Take?

The duration of a classic eyelash extension treatment depends on several factors, such as the skill level of the lash technician, the number of natural lashes a person has, and the desired look. On average, a complete set of classic eyelash extensions can take one to two hours to apply. During this time, the lash technician will isolate each natural lash and glue an individual extension to it.

The number of extensions used during this time can range from 60 to 120 lashes per eye. It’s important to note that the process may take longer if you opt for a more dramatic look or have fewer natural lashes. In addition, touch-up appointments, usually done every 2-3 weeks to maintain the fullness of the lashes, can take between 30 to 60 minutes.

Classic Lashes After 2 Weeks

Typically, eyelash extensions can retain their impressive appearance for two to four weeks, maintaining their full and voluminous feel. However, once the lashes lose their luster and thickness, a touch-up appointment with your lash technician becomes necessary. Compared to the initial lash application, touch-up appointments are usually less expensive.

Classic Lash Extensions Aftercare

Proper aftercare is essential for ensuring the longevity and health of your classic lash extensions. Here are some critical tips to follow:

  1. Avoid getting your lash extensions wet for the first 24-48 hours after the application. This allows the adhesive to cure and set fully.
  2. Be gentle with your lashes. Avoid rubbing your eyes or pulling on your lashes, as this can cause damage to both your natural lashes and the extensions.
  3. Avoid using oil-based products on or near your lashes, as this can weaken the adhesive bond and cause premature shedding of the extensions.
  4. Brush your lashes daily using a clean, soft-bristled lash wand to keep them neat.
  5. Avoid sleeping on your stomach or sides to prevent the lashes from getting crushed or bent while you sleep.
  6. Use a designated lash cleanser to gently clean your lashes gently, avoiding getting any water or purifier in your eyes.
  7. Avoid using mascara on your lash extensions, as this can cause clumping and damage to the lashes.

Classic Lashes vs Hybrid Lashes

Hybrid & Classic lashes are two popular types of eyelash extensions, each offering a unique lash look and benefits.
Classic lashes are eyelash extensions where one individual extension is applied to one natural lash. This creates a natural, subtle look that adds length and thickness to the lashes. Classic lashes are ideal for those who want a natural-looking enhancement to their lashes.

On the other hand, hybrid lashes are a combination of classic and volume lashes. A lash artist applies thinner volume extensions in a fan shape to one natural lash, resulting in a more dramatic look. Hybrid lashes combine both techniques with a mix of individual classic lashes and volume lashes to create a more textured and complete look.

How Can You Remove Classic Lash Extensions?

Removing eyelash extensions can be challenging, and it is always advisable to consult with a lash artist before attempting to remove them on your own. However, if you decide to remove them at home, here are some step-by-step instructions to follow:

Step 1

Gather the necessary tools, such as tweezers, clippers, and eye makeup remover.

Step 2

Clean the lash extensions thoroughly with soap and water to remove debris and glue buildup.

Step 3

Remove the classic lash extensions using tweezers held at a 45-degree angle. If you can’t see the glue, gently scrape it off with a makeup remover wipe.

Step 4

If you encounter resistance while removing the lashes, apply more remover to dissolve the glue and continue pulling gently.

Step 5

Apply petroleum jelly or a similar product to the glue to loosen it.

Step 6

Slowly and gently pull out the eyelash extensions. If you encounter resistance, use tweezers to scrape away any remaining glue.

Step 7

Experts recommend that only professionals perform the removal of classic eyelash extensions. Clients are advised to visit a lash artist to ensure that the extensions are safely and correctly removed.

Classic Eyelash Extension Cost

The cost of a classic eyelash extension set usually falls in the range of $80 to $300 on average. Various factors can influence the price of lash extensions, including the type of extensions selected (such as the material and brand), and the reputation and location of the lash technician providing the service.

How Long Do Classic Eyelash Extensions Last?

Classic eyelash extensions typically last between 4 to 6 weeks, depending on the natural growth cycle of your lashes and how well you take care of them. To maintain the fullness and shape of the extensions, lash artists recommend touch-up appointments every 2 to 3 weeks, as both the attached extensions and natural beautiful lashes shed over time.

Classic Lash Extensions – Main Takeaways

Classic extensions offer a convenient way to enhance the length of your natural lashes and enjoy stunning lashes effortlessly every day. They require minimal upkeep, making it a hassle-free approach to enhancing your appearance and boosting your self-confidence.


1. How Do Classic Hybrid And Volume Lashes Differ From Each Other?

Eyelash extensions come in different types, each with unique features. For instance, classic hybrid and volume lashes are two distinct types of extensions. A skilled lash artist can customize classic hybrid lashes to produce a full and fluffy and more voluminous effect by fusing classic and volume lash extensions. On the other hand, they can attach feather-light multiple lashes to a single natural lash to create volume lashes that result in a more dramatic high-quality and fuller look. Volume lashes typically range in thickness from 2D to 6D, while classic lashes follow a 1:1 pattern, with one extension attached to each natural lash.

2. Is It Possible To Customize Classic Lash Extensions According To My Eye Shape?

Certainly, classic natural eyelash extensions can be tailored by professionals to complement an individual’s eye shape. A skilled lash artist has the ability to assess and recommend the ideal length, thickness, and curl that will blend seamlessly with the person’s natural lashes and accentuate their unique eye shape.
