Understanding Lash Extension Sizes

Lash extensions come in a variety of lengths, thicknesses, and curls. Here’s a breakdown:

Length: Typically ranging from 6mm to 17mm.

  • Shorter lashes (6-9mm) are great for a natural look, especially for clients with shorter natural lashes.
  • Medium lengths (10-12mm) offer a balanced and noticeable enhancement, suitable for most clients.
  • Longer lengths (13-17mm) create a dramatic effect, ideal for clients seeking a bold look. 

Thickness: Usually varies between 0.03mm and 0.25mm.

  • Thinner lashes (0.03mm-0.07mm) are used for volume sets, as they are light and can be applied in multiples.
  • Standard thickness (0.10mm-0.15mm) is popular for classic sets, providing a noticeable yet natural appearance.
  • Thicker lashes (0.18mm-0.25mm) create a more dramatic and mascara-like effect. 

Curls: Common types include J, B, C, D, and L curls. J and B curls offer a subtle lift, suitable for a natural look.

  • C curls are a popular choice, providing a noticeable curl that works well for most eye shapes.
  • D curls offer a dramatic curl, ideal for clients wanting a more open-eye look.
  • L curls have a sharp bend, perfect for hooded or deep-set eyes.


Lash Extension Styles

There are several lash extension styles, each creating a different look:

Natural Style: Mimics the natural lash line, using varying lengths that follow the eye’s natural shape.

Customizing Lash Extensions for Clients

As a lash artist, it's important to customize lash extensions based on the client’s natural lashes, eye shape, and desired look. Here are some tips:


  • Assess the Client’s Natural Lashes: Consider their length, strength, and density. Choose extension sizes that the natural lashes can comfortably support.
  • Consider the Eye Shape: Tailor the lash style to enhance or balance the client's natural eye shape. For example, a cat-eye style can elongate round eyes.
  • Discuss Desired Outcomes: Have a thorough consultation with your client. Understand their daily routine, preferences, and the look they aim to achieve.
  • Aftercare Advice: Educate clients on proper aftercare to maintain the longevity and health of their lash extensions. This includes gentle cleansing, avoiding oil-based products, and regular refills.
