An eyelash extension is a single strand of eyelash made either of synthetic or natural hair that is attached individually or with fans to each natural lash. It is important that the lash technician match the curl of the extensions to the curl of your natural eyelash to ensure an optimal result.

There are many different kinds of eyelash curl types available, with different widths and lengths to help replicate a client’s natural eyelashes.

From the least curly to curliest, there are seven different curl types: J, B, C, CC, D, L, and L+.

With this in mind, let’s dive into the advantages and disadvantages of each type of lash curl.


  • Most natural-looking curl.
  • Specifically intended for clients who have short lashes that point downward not used very often


  • Also best for clients who have short lashes that point downward.
  • Starts straight but has more curl on the end than the J curl, resulting in more “lift” of the lashes.


  • Most popular curl.
  • Intended for clients with a slight curl in their natural lash and will create an open-eye effect suitable for every eye shape.


  • Lifts the lashline and opens the eye.
  • Adds a dramatic effect.
  • Not suitable for clients who have deep-set or hooded eyes.


  • Half-circle shape and the curliest of all the types of eyelash extensions.
  • Dramatically opens the eyes.
  • Perfect for clients with naturally curly lashes.


  • Has a dramatic upper curl that is perfect for clients with hooded or deep-set eyes.
  • The L stands for lift – similar to the lift you get when using an eyelash curler.
  • Provides a better retention rate for clients with short, downward-pointing lashes.


  • Basically, a C or D curl with a flat base.
  • Gives clients with straight, downward-pointing lashes the ultimate lift and curl.

The curl type is not the only thing to take into consideration when getting eyelash extensions done, but it is up there. Once you have decided the length you want, the next decision is curl type.

You can use all the information listed above about all the different curl types to help you come to a decision. The “J” curl is the most natural and a “C” is for the girl who already has naturally curly lashes but wants to add a dramatic flair.

Asian females typically have short, straight, and downward-pointing lashes and the curl of the lash extensions will make a dramatic difference in their look.

All the different types of curls can be combined to create a very unique look that is made just for you. That’s why the job of a lash technician is considered to be an art. They need to be able to put together a set of lash extensions based on many criteria, and especially curl, that suits your face and eye shape the most.
