Decoding Eyelash Sizes and Codes

Eyelash extension codes typically describe the type, length, curl, and volume of the lashes.

Here's a breakdown of the most common combinations and codes you may encounter:

Lash Volume Types

Indicates the number of extensions applied to a single natural lash.

  • Classic (1D): One extension per natural lash for a subtle, natural look.
  • 2D–3D: Two or three extensions per natural lash for light volume.
  • 4D–6D: Four to six extensions per natural lash for moderate volume.
  • 7D–10D: Seven to ten extensions per natural lash for mega volume and dramatic fullness.

    Lash Lengths

    Measured in millimeters (mm), lengths typically range from 6mm to 20mm:

    • 6–9mm: Short lashes for inner corners or a natural look.
    • 10–12mm: Medium length, ideal for everyday wear.
    • 13–16mm: Long lashes for a bold, glamorous look.
    • 17–20mm: Extra-long lashes for dramatic, statement-making styles.

      Curl Types

      Defines the curvature of the lash. Choose based on your eye shape and desired effect:

      • J Curl: Subtle curl, almost straight, for a natural look.
      • B Curl: Gentle curl for a soft, natural enhancement.
      • C Curl: Popular choice, providing a noticeable lift and open-eyed effect.
      • CC Curl: More dramatic than C, perfect for added glamour.
      • D Curl: Strong curl for bold, lifted, and doll-like lashes.
      • L Curl: Straight base with a sharp lift, ideal for hooded or deep-set eyes.
      • M Curl: Straight base with a soft, upward lift for a natural yet lifted look.

        Lash Thickness

        Measured in millimeters and determines how thick each lash extension is:

        • 0.03mm–0.07mm: Ultra-thin for volume lashes (fans).
        • 0.10mm–0.15mm: Standard for classic extensions.
        • 0.18mm–0.25mm: Thicker, less common, for a more dramatic look (not recommended for weak natural lashes).

          Common Examples of Lash Codes

          Here’s how to interpret codes for common eyelash extension styles:

          • Classic 1D-10-C: Single lash extensions, 10mm in length, with a C curl.
          • 3D-12-D: 3D volume fans, 12mm in length, with a D curl for bold volume.
          • 6D-14-M: 6D volume fans, 14mm in length, with an M curl for dramatic lift.
          • 4D-9-B: 4D volume fans, 9mm in length, with a soft B curl for a natural appearance.

            How to Choose the Right Combination

            1. Eye Shape: Consider the shape of your eyes when selecting curl types:
              • Hooded Eyes: L or M Curl for lifted effects.
              • Round Eyes: C or CC Curl for balance.
              • Almond Eyes: Most curls work, especially C or D.

            2. Natural Lash Health: Choose thinner and lighter lashes (e.g., 0.03–0.07mm) for delicate or sparse lashes.

            3. Occasion: Opt for shorter lengths and subtle curls for daily wear and longer, dramatic styles for special events.

            By understanding these codes, you can select the perfect combination to achieve your desired look!
