In the world of eyelash extensions, lengths can vary from a subtle 4 mm to a dramatic 22 mm, offering a spectrum of possibilities. Most beauty salons typically stock extensions ranging from 7 mm to 15 mm to cater to a broad array of preferences and styles.

Short Lash Extensions (5-8 mm)

Ideal for those seeking a subtle eye enhancement, short lash extensions are perfect for inner corner application or achieving a natural look. They’re also suited for lower lash extensions, providing a cohesive and understated appearance.

Medium Lash Extensions (9-12 mm)

The go-to choice for a balance between natural and noticeable, medium lash extensions are versatile, enhancing the central and outer sections of the lash line. They cater well to individuals with medium to short natural lashes, offering an elegant lift without overstatement.

Long Lash Extensions (13-16 mm)

For those aiming to make a bold statement, long lash extensions add significant drama and allure, especially when applied to the central and outer areas of the eye. This range is ideal for individuals blessed with naturally longer lashes.

Extra-Long Lash Extensions (17-22 mm)

Reserved for the daring, extra-long extensions cater to clients craving exceptionally dramatic looks or possessing naturally long, strong lashes. These eyelash extension lengths are typically special-ordered for unique occasions, emphasizing a standout, glamorous eye presentation.

  • B Curl: The B Curl offers slightly more curl, providing a gentle enhancement to your natural lashes.
  • C Curl: This is a popular choice that offers a noticeable curl without being overly dramatic.
  • D Curl: If you’re looking for more drama, the D Curl delivers a significant lift to your lashes.

Lash extensions typically come in various thicknesses, ranging from ultra-fine 0.03mm to a more dramatic 0.25mm. The most common thicknesses include:

  • 0.03mm – 0.07mm: Used mainly for volume lashes, these ultra-fine extensions are lightweight and ideal for creating a fuller look without overburdening the natural lashes.
  • 0.10mm – 0.15mm: Suitable for classic lash extensions, these thicknesses offer a more noticeable look while still maintaining a degree of naturalness.
  • 0.18mm – 0.25mm: These thicker extensions are less commonly used due to their weight but can be suitable for clients with strong, healthy natural lashes seeking a bold, mascara-like effect.

Cat eye eyelash extensions length, curl, and thickness

Length: For a cat-eye look, you’ll typically want to use shorter lengths (around 8-10mm) towards the inner corner of the eye, gradually increasing to longer lengths (up to 13-15mm) towards the outer corner. This creates the signature winged appearance that lifts and elongates the eye shape.

Curl: A stronger curl, like a C or D curl, is ideal for cat-eye extensions. These curls provide a dramatic lift and curvature at the outer edge of the eyes, emphasizing the cat-eye effect.

Thickness: The thickness can vary based on the desired intensity and the health of the natural lashes. For a more subtle cat eye, 0.10mm to 0.15mm thickness may be appropriate. For a more dramatic look, some may opt for up to 0.18mm, but always consider the natural lash’s ability to support this weight.

Length: Classic extensions typically range from 9mm to 12mm, providing a natural look that enhances the existing lash line without appearing overly dramatic.

Curl: B or C curls are popular for classic lash extensions because they offer a natural lift that suits most eye shapes. These curls enhance the eyes’ openness without the dramatic effect of higher curls.

Thickness: A thickness of 0.10mm to 0.15mm is standard for classic eyelash extensions. This range offers a noticeable yet natural enhancement, mimicking the look of mascara without the clumps.

Length: Doll eye extensions often use a uniform length across the eye or slightly longer lengths in the middle of the lash line to create a rounded, open-eyed look. Lengths around 10mm to 15mm in the centre and slightly shorter on the ends achieve this effect.

Curl: C curls are well-suited to doll eye extensions for their balanced lift, which helps open up the eye equally across the lash line, contributing to the doll-like appearance.

Thickness: A thickness of 0.10mm to 0.15mm works well for doll eye extensions, offering fullness and visibility that contribute to the wide-eyed look without overwhelming the natural lashes.
