Classic vs. Volume Lashes
Classic lashes are considered the original (single-layer) method of eyelash extensions. These lashes are perfect for clients who already have a lot of lashes, but want to add more length.
Volume or 3D lashes are also known as the multi-layer method. This is the only patented technique for applying Volume eyelash extensions. The lash extensions used in this method are significantly thinner than the lash extensions used for the classic lash method.
Volume lashes are lighter and give the client a fuller look. Volume lashes tend to last longer, requiring refills less often than classic lashes. Volume lashes are prefect for clients who don't have a lot of lashes, have sparse lashes, bald spots or just want a more dramatic look without having to use a thicker lash.
