How to Choose Eyelash Extension Curl Types for Your Eye Shape

Choosing the right curl type is one of the most important decisions in lash extension application — the wrong curl can make eyes look smaller, unnatural, or uncomfortable. This guide covers every curl type and exactly which eye shapes they suit best.

Curl Type Reference Guide

• B curl: Very subtle curl; almost straight; best for clients who want minimal enhancement
• C curl: The most popular curl; natural-looking upward sweep; suits most eye shapes
• CC curl: Between C and D; more lift than C without the drama of D; ideal for soft glam
• D curl: Dramatic upward curl; creates maximum lift and open-eye effect
• DD curl: The most dramatic standard curl; very tight upward curl; best for mega volume
• L curl: Flat base with sharp upward bend; designed for hooded and monolid eyes
• LC curl: Flat base with C curl bend; softer version of L curl
• M curl: Flat base with D curl bend; maximum lift for hooded eyes

Curl by Eye Shape

Almond Eyes

The most versatile eye shape — suits C, CC, and D curls. C curl for natural everyday looks; CC for soft glam; D for dramatic volume sets. Avoid B curl — too subtle for almond eyes.

Round Eyes

Benefit from curls that elongate rather than open further. Best: C curl — adds lift without increasing the round appearance. Avoid D and DD curls — they make round eyes appear even rounder.

Hooded Eyes

Need curls that lift away from the lid and remain visible above the hood. Best: L, LC, or M curl — the flat base sits flush against the lid while the upward bend ensures the curl is visible. Standard C and D curls often disappear under the hood.

Monolid Eyes

Benefit from dramatic upward lift to create visible curl from the front. Best: D or M curl — creates the most visible lift on monolid eyes. L curl also works well for a more natural result.

Downturned Eyes

Benefit from curls that lift the outer corner upward. Best: CC or D curl at outer corners with C curl at inner corners — the mixed curl map corrects the downward angle and creates a lifted appearance.

Deep-Set Eyes

Benefit from curls that bring lashes forward rather than just upward. Best: C or CC curl — the forward sweep makes lashes more visible. Avoid very tight D and DD curls — they curl back toward the brow bone.

Mixing Curls in a Lash Map

Professional lash maps often use multiple curl types in a single set — for example, C curl at the inner corner, CC curl at the center, and D curl at the outer corner for a cat eye effect. Mixing curls creates more natural, dimensional results than using a single curl throughout.
