You'll be asked about thickness when you getting lashes, hope will help you out if you are confused about it. So here is a guide to help you be prepared for your consultation and understand what your lash artist does while your eyes are closed.

What Is Lash Thickness?

Eyelash Extension Thicknesses range from .03mm to .30mm. Thicknesses of 0.20mm or above are being phased out in the lash industry worldwide because they are too heavy for most natural lashes to support.

0.03–0.05mm	Mega Volume	Advanced artists
0.05–0.07mm	Volume	3D–10D fans
0.10–0.12mm	Natural	Weak lashes
0.15mm	Classic	Everyday look
0.18–0.20mm	Dramatic	Strong lashes
