Flat lash and Mink Lash: A comprehensive Comparison

As a lash manufacturer, we would like to contribute some technical view on how their difference. Let’s discover it in this post. I hope that it’s not too difficult for you to understand.
Table of Contents
1. Comparison on the weight
Flat lash (so called ellipse lash or ellipse flat lash) is famous for its hack of weight while remaining the ability to enhance the full look on classic extension sets. We strongly believe that reducing the weight had been the purpose of its invention right from the beginning, not just a great result by luck.

2. Comparison on the retention
The shape of the flat hair is intentionally designed for the retension. The following image can prove it.
While it’s called ellipse lash, the most common shape of its nowaday is actually a “8” in stead of a real ellipse. I mean its has a concave structure instead of a convex structure.
Its holics fit well with the round face of the natural lashes, making a wider glue bonding area, multiplying the retention.

3. Comparison on the level of user-friendliness
Normal round mink lash is more user-friendly. It’s easy to grab up and easy to apply. We can apply the round lash to 4 sides of the natural lash (upper, under, 2 sides) while we can apply to only 2 sides (upper, under) with the flat lash.

4. Comparison on the cost
The production cost of a box of flat lash is normally at least 10% higher than a box of normal round mink lash. In the world of retail, the gap between their price is normally 20% different.
5. Comparison on the variety
a. Compare the variety of the color
Theorically speaking, if we have any color for the round mink lash, we can have the same one with flat lashes. However it’s not the case in reality. Due to the big gap in the market demand at the moment, we have much less colors on the ellipse lashes.

b. Compare the variety of the thickness
The application of flat one is almost for classic sets while the round mink lash can be used for volume, hybrid… sets too. Therefore, we have more diffrent thickness with the round lash.
- Round mink lash thickness: 0.03 0.04 0.05 0.06 0.085 0.1 0.12 0.15 0.18 0.2 0.25…. (wider range, from very thin to very thick)
- Flat lash thickness: 0.12 0.15 0.2 0.25… (narrow range, focus on thick one)
c. Compare the variety of the length
The flat one is featured with the flip tip on the only 1 base. It doesn’t allow the lash to be too short like 4mm-5mm like its possibility on the round mink lash.
Summary

Yes. it’s about 60% lighter

Yes. It’s more expensive of around 10%-30%
Is flat lash have a better variety?
