If you're going for a more textured and fuller look, hybrid is the way to go. Rather than classics, more volume is added. It's a mixed ratio or classic and volume, using individuals and fans.
A volume set may be your option if you're looking for a fuller effect on your lash line. This gives a fluffy dark appearance; all lashes will be placed with fans to create dimension. No spikes are added to tis set in order to achieve a beautiful cat eye.
Fill ins should be done max 2 weeks. If you have consulted with me knowing your growth is slow, then the max is 3 weeks. Fills should only be done once within a new set.
