Understanding Lash Diameters
There is a lot of confusion surrounding safe lash weights, and equivalent weights when dealing with volume fans.
Eyelashes are not easily measurable due to their extremely light weight. Lashes are described by their diameter and length. We should never confuse diameter with weight.
It is a common misconception, for example, that 2 x .10 lashes would weigh the same as 1x .20 lash. This is incorrect. In the following example, let's assume the eyelash extensions are manufactured by the same company from the exact same materials.
This diagram represents a cross-section of individual eyelash extensions. The large circle is a lash with a diameter of .20mm. The two smaller circles are lashes with a diameter of .10mm. In this example, all lashes are the same length. As you can see, there is quite a bit of negative space remaining and it is obvious that 2 x .10mm lashes would have far less mass than 1 x .20mm lash, and therefore be lighter.
It is now generally agreed across the lash industry that the safest diameters for classic lashes are 0.10, 0.12 0.15mm.
The safest diameters for volume are 0.07 & 0.05mm, while 0.03 is used for mega-volume.
So how many volume lashes can we fan safely, and what are their equivalent classic diameters? We've put together this helpful ready reckoner for lash diameters:
At MYSTIQ we value the health of the natural lash and will never stock lash lengths or diameters that are known to be damaging. Please consider the length and strength of an individual client's lash when selecting an appropriate extension.
