Flat lash: New game changer or passing trend?
Flat lashes have become much more popular since their launch several years ago, raising the question: Will they completely replace traditional round lashes, or will they fade away like many other emerging trends?
In this article, We will dig deeper into its pros and cons then using our own evaluation to predict its future.

1. WHAT IS THE FLAT LASH?
Flat lash is a new type of synthetic eyelash. What makes it different from traditional synthetic eyelashes lies in its shape. The lash fiber doesn’t have the usual round shape but is instead elliptical or in the shape of an ‘8’.

2. WHERE WAS THE IDEA OF FLAT LASH COME FROM?
2.a. The disadvantage of the round lash
Lash extensions always add more weight to the natural lashes, which isn’t good. Lash artists need to balance the density and the weight they add. As a result, people began looking for a solution.

The bonding area between two round hairs is minimal, which makes their connection have poor retention.

2.b. Natural hair is not round
By observing real mink hair, people found that it is never perfectly round. This means that a perfect round shape is not necessary. It inspired the idea of changing the shape of the lash while maintaining a full look.
2.c. Combination of 2-3 hair in classic sets
Have you noticed that 2 fibers of demension 0.03 is less weight than a fiber of demension 0.06 mm?

Many lash artists combine 2 or 3 fibers of thin lashes in classic sets instead of using a thicker fiber to balance the weight and achieve the desired look. This idea was a strong inspiration for the creation of flat lashes.
You may ask, why aren’t people satisfied with these techniques and instead work so hard to go further? There are two reasons behind this.
- Lash fiber producers know that, they can do even much better. That’s how the Super Flat Lash was created.

- Grabbing one fiber is always easier than grabbing two fibers at the same time, right? Which one do you think that is more user-friendly?
3. WHAT IS ITS ADVANTAGE
3.a. More light-weight
Similar to the way the lash artists hack the weight by removing negative weight in 2.c above, Flat lash and its invovated version can keep the same witdth. That’s how it getting much much more lightweight.
3.b. Softer and fuller look
The flip tips double the full look, making its softer too. On this point, I’m quite sure that you’ve got the idea, so I will not go too much deeper.

3.c. Better retention
There are at least 2 reasons that make a flat lash and the natural lash usually has a much better retension.
- Firstly, the glue-bonding area is wider
- Secondly, it puts less weight on the natural lash and the connection.

4. IS THERE ANY DISADVANTAGE?
- Flat lashes is not really suitable to make volume fans.
Almost all techniques of making volume fans tought by lash masters are one with round lashes. And you can easily imagine how different hairs of round lash combine together to make a thin base of a volume fans, but can you imagine it with flat fiber instead?

- More Difficult to produce and use
People can argue that “I don’t need to make the fans from flat lash by myself, I can ask Sen Lash Factory to help me making promade fans of flat fibers”. Yes, That’s true. We can help. But the point here is it’s more dificult to make a fans of flat lashes than round lashes, making its productivity is lower (like a limitted version) and the cost is higher.
Another important point here is that: grabbing a flat lashes requesting a lash artist more attention than a round lash. Different angle between the tweezer and the lashes not create much more different in the case of round lash, but not in the case of flat lashes.
- More expensive
As you many know, the round lash is cheapest to produce. We have a long history of producing synthetic round fiber. The round fiber is not only used for lash, but also mainly used for other products like brush. The application of brush is much wider than the lash. And you can image, who wants a brush with its hairs in flat shape? I mean, almost all of the production facility is created to produce round fibers.

5. WHEN SHOULD WE USE FLAT LASH?
It’s more suitable for classic set than volume one. There is no limitation of eye style, the same as regular individual lashes.
it’s especially suitable with the case that:
- You would like to increase the eyeliner effect
- More drama and texture
- Clients has thin or weak natural lashes
- …
6. PREDICT THE TREND OF FLAT LASH?
Do you know that, besides flat lashes, there are many other shape invented

And none of them are now replacing the round lashes 100%, right?
Yes, From our point of view, With its pros, flat lashes can increase its market, but it can NOT replace 100% the round lash due to its own cons, even in classic sets only.
