Lash Extension Types
The Classic eyelash extensions are – as their namesake – classic. They are simple, beautiful, natural-looking lash extensions. They are applied on a 1:1 ratio, which means one extension on one natural lash. This allows you to achieve an understated, natural enhancement. 
If you want eyelash extensions that will only be noticeable to your friends who know what eyelash extensions look like, classic eyelashes are a great place to start. Classic eyelash extensions come in a range of materials, thicknesses (1 – 1.5mm) and styles, so talk to your technician about the look you are trying to achieve.  
Classic lash extension application typically takes 1.5 to 2 hours (if someone tells you they can do it in under an hour, it’s not a good sign). The result should be soft, natural-looking lashes your friends won’t know isn’t just a great mascara. 
What are volume eyelash extensions? – Volume eyelash extensions offer you a full, better-than-falsies look that gives you some serious glamour and drama. Volume lashes (also known as Russian volume lash extensions) were invented by Russian technicians only recently. And involve applying a “fan” of lash extensions to one lash. So, instead of the 1:1 ratio of classic lashes, you may have a 1:3 or 1:5. This is how the luxurious volume is achieved! 
2D, 3D, 5D define the number of lashes in each fan. So, if a lash look you like is “3D” it has a 1:3 ratio. 2D and 3D lashes give a natural, voluminous look, while higher volumes give a dramatic look. The highest volume you are likely to find is 10D – though this is an extreme falsie look! 
Hybrid lashes are a 70-30 mixture of both classic lashes and volume lashes. Choosing hybrid eyelash extensions gives you the best of both worlds. You can try volume lashes for the first time and get the beautiful Kardashian look, as it was first popularised by them. 
This look has since spread across Hollywood. Stars love it because it offers a wispy, natural lash line with a little drama. The look is achieved by mixing classic lashes and volume lashes placed strategically to frame the eyes.
