Mega volume lashes are pretty similar to traditional volume lashes. However the key difference between mega volume and traditional volume is the number of lash extensions that are used to create the fan and the diameter of the extensions in the fan. A set of traditional volume lashes uses 0.07 extensions to create a fan with up to 5 lash extensions. Mega volume sets use 0.05 and 0.03 lash extensions to create a fan with up to 16 lash extensions. With Mega volume, you can apply up to 16 extensions on one natural lash. This makes it very voluminous or "mega" indeed.
