Understanding Lash Extension Size Measurements

Navigating through the world of different sizes of lashes involves understanding the intricate details of various measurements. These measurements, including length, curl, and thickness, are pivotal in determining the final look and style of lash sets.

  • Length: Lash extension length varies typically between 5mm to 20mm. Shorter lengths are ideal for a subtle, natural look, often used for inner corners or lower lashes, while longer lengths cater to a more dramatic and bold appearance. The chosen length should complement the client’s natural lash length to avoid discomfort or damage.
  • Curl: The curl of lash extensions is categorized into various types, such as B, C, D, and more. Each type of curl offers a different degree of lift and curve, influencing the eye’s openness and the overall drama of the look. For instance, a C curl provides a noticeable lift, suitable for a wide-eyed effect, while a D curl offers a more dramatic curvature for a striking appearance.
  • Thickness (Diameter): Thickness typically ranges from ultra-fine diameters like 0.03mm to thicker options like 0.20mm or more. Thinner lashes create a more natural and lightweight look, ideal for clients with finer natural lashes, while thicker lashes offer boldness and volume, suitable for clients with strong, healthy natural lashes.
  • Combining Measurements for Customization: By varying these measurements, lash artists can tailor lash extension sizes to individual preferences and facial features, ensuring a unique and flattering look for each client.
