Complete Guide to Lash Extension Supplies: L, M, LC, LD, LB, and LJ Curls Explained

L, M, LC, LD, LB, and LJ curls are the flat-base curl family — each designed to deliver lift and visibility for hooded, monolid, and downturned eyes where standard C and D curls disappear into the lid fold. This guide covers what each curl does, which eye shapes they suit, and the essential supplies you need to work with them professionally.

The Flat-Base Curl Family: What Each Curl Does

  • L curl — classic flat base with sharp 90° upward bend; maximum lift; best for very hooded eyes
  • M curl — flat base with softer, more gradual upward bend; versatile; suits most hooded eye clients
  • LB curl — flat base with B-curl tip; slightly softer than L; good balance of lift and natural look
  • LC curl — flat base with C-curl tip; moderate lift with a natural-looking curl at the tip
  • LD curl — flat base with D-curl tip; dramatic lift with maximum curl at the tip
  • LJ curl — most dramatic flat base; extreme lift for severely hooded or downturned eyes

Eye Shape Matching

  • Hooded eyes: M or LC curl for moderate lift; L or LJ for maximum lift
  • Monolid eyes: M or L curl for visible lift above the lid
  • Downturned eyes: LD or LJ curl at outer corners to counteract the downward direction
  • Straight natural lashes: Any flat-base curl provides dramatic lift without requiring a naturally curly lash

Essential Supplies for Flat-Base Curl Application

  • Flat-base curl lashes — M, L, LC, LD, LB, or LJ depending on client eye shape
  • Lash adhesive (0.5–1s dry) — slightly slower dry time recommended for flat-base placement precision
  • Eyelash primer — essential for removing oils before flat-base application
  • Isolation tweezers — fine-tip for separating natural lashes
  • Volume tweezers — for easy fanning versions
  • Eyelash bonder — seals flat-base bonds immediately after application
  • Silicone eye pads — protect lower lashes during application

Application Tips for Flat-Base Curls

  • Place the flat base flush against the natural lash — the entire base must contact the natural lash for a secure bond
  • Use a natural or squirrel lash map — avoid cat-eye maps which can work against the lifting effect
  • Ask the client to open their eyes during application to confirm the curl is visible above the lid fold
  • Keep lengths shorter at inner corners (8–10mm) and longer at outer corners (12–14mm)

🛒 Primer + Bonder — Essential for Flat-Base Retention

Flat-base curls require a clean, oil-free surface for the base to bond correctly. Use Eyelash Primer before application and Eyelash Bonder immediately after to maximize retention.
