The Classic eyelash extensions are – like 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.
