The so-called antibacterial eyelash is adding silver ion in the PBT material to enhance the antibacterial function of the false eyelash.

polyethylene terephthalate (PET): also known as polyester. It is used for “horn-shaped” bunches of false eyelashes.

Hydrogenated plastics (PVC): often used for hair extensions, wigs, etc. It deforms at low temperatures.

Animal fur lashes (animal hair, protein): Ten years ago, there was a batch of pig hair, mink, fox, squirrel, and Mustela sibirica hair in the market, but the circulation quantity was minimal. This kind of hair has excellent luster and texture (soft) because it is a natural material, “the length, radian, the thickness is not equal,” the length will not exceed 6mm, there is no possibility of 13mm mink lashes, such restrictions, so animal hair is challenging to use in practice.

To look more natural, choose 0.1mm, 0.12mm, 0.15mm. Other diameter false eyelashes can be used in a small amount to present a full effect and shorten the grafting time. You should combine the customer’s original eyelash state, the desired shape, durability, and other aspects, then make a choice.

The eyelash length
The length of false eyelash extensions is mainly in 6-15mm, the commonly used range is 8-12mm, among which the most frequently used length is 9-11mm.
