With the abundance of options when it comes to lash thickness, length, and curl, determining what will suit each client can be a daunting task. Not only do we need to consider personal preferences, but also the client's unique eye shape and overall facial features. In this article, we will explore the different types of lash curls, provide insights on selecting the ideal length and thickness, and discuss which curls complement specific eye shapes. Let's dive in!


The Different Types of Lash Curls

As a lash artist, it's essential to have a wide array of lash curls at your disposal to cater to various client needs. Here are some of the basic lash curls offered by OutLash, listed from least curly to most curled:


C-Curl: The C-curl is widely recognized as the most versatile and popular curl. It provides an open-eye effect without appearing overly dramatic, making it a common choice among clients.


D-Curl: The D-curl has gained popularity due to the trend of achieving more lift and visible lash lines. This curl offers a noticeable lift and dramatic effect, satisfying clients seeking a bolder look.


DD-Curl: Our DD curl lashes are perfect for clients who desire an "extra" dramatic lift. This curl is ideal for those who want their lashes to make a bold statement.


L-Curl: L-curl lashes resemble the shape of an "L" and also contribute to lifting the lash lines. They are particularly suitable for clients with monolids or individuals who are seeking a unique lash style.


Keep in mind that the tightness of curls may vary across different brands.


Choosing the Right Length and Diameter of Eyelash Extensions

 When it comes to eyelash extensions, they are available in various lengths and diameters, typically ranging from 0.03mm to 0.20mm. At OutLash Extensions Pro, we offer lashes in 0.03, 0.05, 0.07, 0.10, 0.12, and 0.18 diameters. While some lash artists may opt for diameters above 0.18mm, it's important to note that most professionals prefer to avoid excessive weight on the natural lashes. In fact, in the earlier days of the industry, lash artists commonly used 0.25mm lashes before the introduction of volume lashes.


To ensure the best outcome, it is recommended to follow this rule of thumb: when a client desires a full, dense, and dark lash line, opt for shorter lengths with more lashes per fan. For example, consider using 0.03mm lashes in 10mm length with 8D (8 lashes per fan), while ensuring the natural lashes can support this weight. Longer lashes tend to appear lighter and more wispy.


Engage in a conversation with your client to determine her preferred style, and take the opportunity to explain the characteristics of her natural lashes. By understanding her needs and assessing her natural lashes, you can proceed accordingly to deliver a customized and satisfying experience.



Selecting the appropriate curl for eyelash extensions plays a pivotal role in achieving the desired look for your clients. By offering a variety of curl options and understanding how each curl complements different eye shapes, you can enhance your clients' natural beauty. Additionally, considering the right length and thickness, while being mindful of the natural lashes' capacity, ensures a seamless integration of the extensions. With these insights and personalized consultations, you can provide exceptional lash services that leave your clients feeling confident and glamorous. Remember, each client is unique, and by tailoring your approach, you can create stunning lash transformations that stand out from the crowd.
