What have you known about volume lash extension?

Talking about volume lash extension, everyone working in this field has at least heard of it, right? But there are a few small but interesting details you may not know about volume eyelash. Volume eyelash extensions is a technique that originated in Russia, which is why it is sometimes called Russian Volume Lashes. This is the most modern eyelash extension style in Western European style, impressing with thick, long and curved eyelashes, creating extremely beautiful eyes.

In the volume lash technique, the lash technician will create fans that cluster from 2 to about 5 eyelashes into one fan and then attach it directly to the real eyelid. Today, thanks to the growing eyelash industry, lash technicians can use pre-made fans to ensure uniformity and save customers time. But in the past, lash technicians had to create fans themselves while applying eyelash extensions to customers.

However, no matter the method of volume eyelash extensions, technicians need to understand important factors that affect the quality of a set of eyelashes, including the size and weight of the eyelashes.

Suitable size and weight are the first thing to consider when doing a volume lash extension.

There are many questions surrounding choosing a safe eyelash weight and size for customers. The answer of an expert in connecting volume lash extensions is that it must be carefully calculated for each individual customer’s eyes.

If you choose the wrong size and weight of eyelashes in your volume lash application, many serious problems will occur, such as causing natural eyelashes to break off and prevent them from growing back due to damaging hair follicle cells in the eyelid. Or to be gentler, it will also cause volume lash extensions to not achieve a beautifying effect, on the contrary, making the eyes look saggy because the lashes are too heavy.

Tips to choose size and weight for volume eyelash extensions

Normally, the size of eyelash extensions is determined by the diameter. And for the majority of genuine eyelash extensions, larger diameter means greater weight. When lash technicians attach eyelashes with a diameter larger than the diameter of the customer’s natural eyelashes, they will easily break. Therefore, the most important tip is that the eyelash extensions must always be smaller than the natural eyelashes. 

To control this well, you need to pay attention to two factors of eyelash extensions: the number of fibers per fan, often denoted D, and the thickness of each fiber. Below is a table summarizing how to create thickness for volume lash extension based on eyelash diameter that you can refer to.

Remember the numbers in the table to help you make the right choice for your customer in volume lash application. Simply put, if the diameter of the eyelashes decreases, the number of eyelashes will increase to maintain a stable weight of the eyelash extensions!

And there is one more table that you will definitely be grateful for when reading this article because it tells you about the relationship between diameter and weight of eyelashes. Let’s me explain more in the next part!

Diameter (mm)

Weight (mg)


















Which size and weight is the best for a volume lash extension?

For professional lash technicians, they all understand that there is no certain number for the standard size and weight for volume lash extensions. However, in reality, most people want to have beautiful, natural eyelashes that are thick and curved but not too awkward. Therefore, most lash technicians will use fibers with a diameter of about 0.05 mm – 0.07 mm. Only in special cases, when customers want extremely thick and dense eyelashes, do they use 0.15 mm or more. 

But the most important thing is that lash technicians need to carefully consider the type of fiber that is suitable for the customer’s real eyelashes because by doing simple math from table 2, you can see that not every fiber you use will have a lower weight. Where are you?

I’ll show you an example of 1 0.15 mm eyelash. It has a weight of 0.17 mg. Meanwhile, if you create this fiber from 4 fibers with a diameter of 0.07 mm as shown in table 1, each fiber is 0.04 mg, you will immediately have a fiber weighing only 0.16mg. 

The reason for this phenomenon is called negative space. The picture below will help you visualize and explain this principle. Simply put, in the same box, if you pour water into smaller spheres and then fill the box, the volume of water will be limited by the spheres so you will get less than if you pour directly. Fill that box with water.

Volume lash technique for different types of natural eyelashes

This may be the part that lash technicians want to read the most. In this section, I will reveal a few tips that can be applied to create a beautiful set of volume lash extensions for many different eyelash and eye shapes.

1. For thin lashes

For people with naturally thin, short, sparse and weak eyelashes, the most suitable fiber to add a set of volume lashes is a fiber with a diameter of about 0.01 mm to 0.07 mm. Usually, Asian women and women aged 50 and over will fit these fiber sizes. In general, Asian women have thinner and shorter eyelashes than those in America, Europe or Africa. Furthermore, women over 50 years old have eyelashes that become weaker and thinner. Therefore, the size of the thin eyelash extensions will look more natural and adhere better to the real eyelashes, limiting damage to the real eyelashes.

2. For healthy and strong lashes

In contrast to Asia, European girls, African girls,… and young women often have thicker, longer and healthier eyelashes. Therefore, fibers with a diameter of 0.10 mm or more will help add a darker, more voluminous feeling to the eyelashes without fear of heavy weight causing eyelash breakage or damage to the eyelid area.

For these normal healthy straight eyelashes, when placing the eyelashes, you can optionally place them from top down, bottom up, left or right.

3. For damaged natural eyelashes

When applying makeup, some women use eyelash curlers incorrectly, which can cause the eyelashes to break. At this time, if the eyelash fan is not applied carefully, the lash technician can cause the volume lash extension to reveal flaws and be uneven. So lash technicians need to pay attention to the correct position of eyelash placement to cover the defects of natural eyelashes. For lashes that are slightly slanted to the left or right, you should place the lash fan in the opposite direction. As for broken eyelashes that curl upwards, you should place the eyelash extensions from the bottom up so that it has the firmest and most beautiful grip.

4. For drooping eyes

For those of you with drooping eyelids, whether naturally or due to unwanted eyelid surgery, it can unintentionally make your face look a bit sad and not bright. In volume lash application, if the lash technician is not skillful in choosing the curvature, it will accidentally make those eyes even more lifeless. So the appropriate curvature to help a drooping eye look sharper is the U curvature. Eyelashes with this curvature will help cover large and drooping eyelids, making the eyes look more flexible. At the same time, based on the customer’s wishes, you can also use 4D or 5D fan eyelashes to better cover drooping eyelids.

The eyelash extension process for customers is not pleasant at all, so if the lash technicians’ techniques are good, shortening the eyelash extension time is something that every woman likes. So to shorten the eyelash extension time, let’s see a few more notes below!

1. Use high-quality glue
