L Curl and M Curl lashes are both designed to open the eye and create lift — but they work differently and suit different eye shapes. Choosing the wrong curl for a hooded or monolid client is one of the most common reasons a set looks flat in photos and disappears when the eye is open. Here's how to tell L curl vs M curl lashes apart and when to use each.
Quick Verdict
Choose M Curl if your client has a hooded eye or a downward-pointing natural lash and needs M curl lashes for hooded eyes that start straight at the base before lifting — the flat base prevents the extension from disappearing under the hood.
Choose L Curl if your client has a monolid, very hooded eye, or extremely straight natural lashes and needs L curl lash extensions for monolid eyes with maximum lift from the root — the sharper base angle creates a more dramatic upward direction that traditional curls cannot achieve.
Not sure? M Curl is the safer starting point for most hooded clients. L Curl is the upgrade when M Curl doesn't deliver enough lift.

When to Use Each Curl
M Curl — Best Lash Curl for Hooded Eyes
M Curl lashes for hooded eyes have a flat base that sits flush against the natural lash before curving upward at a moderate angle. This flat base is what makes them the best curl for hooded eye lash extensions — it prevents the extension from curling back into the hood and disappearing when the eye is open. The result is a softer, more subtle lifted look that works for everyday wear without looking overdone. M curl lash extensions are the go-to for clients with downturned or slightly straight natural lashes who want a natural, open-eye effect.
- Clients with hooded eyes who want a natural, open-eye effect
- Clients with downturned or slightly straight natural lashes
- Everyday professional wear where a dramatic curl would look out of place
- Clients transitioning from standard curls (C, D) who aren't seeing enough lift
- W-shape or YY sets for hooded eyes where fan visibility is a priority
L Curl — Best Lash Curl for Monolid Eyes
L curl lash extensions for monolid eyes have a sharper base angle than M Curl, creating a more aggressive upward direction from the root. For clients with monolid eyes or extremely straight natural lashes, this sharper angle is what allows the extension to clear the eyelid and remain visible when the eye is fully open. The L Curl family — L, LJ, LB, LC, LD — offers a range of tip curl intensities, giving you fine control over how dramatic the finished look is. LB and LC curl lashes are the most commonly used for everyday hooded and monolid sets.
- Clients with monolid eyes where standard curls disappear completely
- Clients with very hooded eyes where M Curl still doesn't deliver enough lift
- Clients with extremely straight or downward-pointing natural lashes
- Editorial or event sets where maximum eye-opening effect is the brief
- Volume and Camellia sets for hooded eyes where fan visibility is critical
What are M curl lash extensions good for?
M curl lash extensions are best for clients who need extra lift without going too dramatic. They work especially well on hooded and slightly downturned eyes because the flat base helps the lash sit neatly against the natural lashes — the most natural-looking lash curl for downturned eyes that still delivers visible lift.
What are L curl lashes good for?
L curl lashes are ideal for clients who need a more pronounced lift, especially on monolid, very hooded, or straight lashes. These lash extensions for hooded eyes create a pointed shape and a stronger upward finish, which makes the eyes look more open and defined — the best curl for monolid lash extensions where standard curls simply don't stay visible.

How to Make the Final Call
Ask two questions during your consultation when choosing between L curl vs M curl lashes:
- How hooded is the eye? Slightly hooded — start with M Curl lashes for hooded eyes. Very hooded or monolid — go straight to L Curl lash extensions for monolid eyes (LB or LC curl lashes for most clients).
- What is the natural lash direction? Downward-pointing lashes need a flat base to prevent the extension curling back into the lid. Both M and L Curl have flat bases — the difference is how aggressively they lift from that base.
When in doubt, use the Special Curl range which covers M, L, LJ, LB, LC, and LD in a single product — you can adjust the curl variant at the next fill based on how the client's eye responds.
