Lash Curl Guide: J, B, C, CC, D, L, M & LC

Compare J, B, C, CC, D, L, M and LC lash curls by profile, direction and visible lift for professional lash design.
J, B, C, CC and D lash curl comparison chart

Start with direction

J through D compare conventional curves. L, M and LC use straighter lower sections and more directional transitions.

JStraightest and most understated
BGentle curve with subtle lift
CBalanced and versatile
CCRounder with stronger lift
DBold conventional curve
LStraight base with pronounced lift
MStraight base with smoother lift
LCStraight base with a softer curve

Compare profile and visible lift

Curl names can vary slightly between manufacturers. Use this guide to compare profiles, and always check the actual tray.

Curl Profile Visual direction Useful starting point
J Straightest conventional profile Soft and natural Minimal visible curl
B Gentle conventional curve Natural with subtle lift Softer transition
C Balanced curve Open and versatile Adaptable everyday direction
CC More rounded curve Lifted and defined More visible curl than C
D Strongest conventional curve here Bold and highly lifted Curl is a prominent design element
L Straighter lower section with pronounced lift Angular and directional A sharper transition is intentional
M Straighter lower section with smoother lift Lifted and elongated Directional lift with a softer transition
LC Straighter base with curved upper profile Balanced specialty direction A bridge between straight-base and curved effects

Two curl families

Specialty profiles differ from conventional profiles in lower-section geometry, which changes the silhouette. They are not simply more curled versions of conventional profiles.

Conventional curls: J, B, C, CC and D

J begins relatively straight. B adds a gentle curve. C provides a balanced reference point. CC creates a rounder profile, while D gives the strongest conventional curve in this guide.

  • Move from understated direction toward stronger visible lift.
  • Compare the front and side view before choosing.
  • Use the actual tray profile when changing product lines.

Before choosing a curl

Choose a curl based on the client, the design goal and the complete fiber profile.

  • Natural lash direction: compare the extension profile with the visible direction and condition of the natural lashes.
  • Front and side view: decide how much lift and directional change should be visible from both angles.
  • Length and layering: the same curl can look different when length, layer and placement change.
  • Diameter: curl controls direction, while diameter controls the visible fiber profile. Read the diameter guide.
  • Finish: Matte Black and Ultra Black change contrast, not curl geometry. Read the finish comparison.
  • Manufacturer consistency: compare actual trays because the same curl name may not produce identical geometry.

Shop by curl direction

Choose J and B for softer direction, or explore L, M and LC when a straighter base and specialty transition are part of the design.
