Classic + 2D, 3D Lashes are just like the name says – a combination of classic and volume (2, 3) lashes. This method is suited for people who like the classic look but want a little bit more.
The terms 2D, 3D are used to describe how many lashes are in the fan or bouquet of lashes. So 2D lash means that 2 extensions are placed onto one natural lash, 3D means 3 lashes; and so on.
On half of your lashes, classic technique is used – the extensions are applied one by one – just one single eyelash extension on a single natural eyelash. On the other half fans consisting of 2 or 3 lash extensions (2D, 3D) are applied.
