Lash curl determines lift, drama, and visibility above the lid.
CC curl = most versatile, suits most eye shapes. D curl = maximum lift, hooded and monolid eyes. L/L+ curl = flat-growing lashes, extreme lift.
Rule: match curl to natural lash direction first, then desired look.
What Is Lash Curl?
Lash curl refers to the curvature of the extension from base to tip. A stronger curl creates more upward lift and a more open-eye effect. The right curl depends on your client's natural lash direction, eye shape, and desired look. Choosing the wrong curl is one of the most common reasons extensions look flat, disappear behind the lid, or appear overdone.
CC curl is currently the most popular curl globally, accounting for an estimated 50–60% of all lash extension sets. It offers a balance of lift and naturalness that suits most eye shapes and is the recommended starting point for new artists. D curl is the second most popular, particularly for Asian and hooded eye markets.
Who Is This Guide For?
- Lash artists selecting curls for different client eye shapes and styles
- Beginners learning which curl to stock and when to use each
- Artists working with hooded, monolid, or downturned eyes who need lift-specific guidance
- Wholesale buyers building a complete curl range for their kit
Who Should NOT Use Strong Curls (D, L, L+)?
- Clients with deep-set eyes — strong curls can look overdone and touch the brow bone
- Clients wanting a very natural, barely-there look — use B or C curl instead
- Clients with upward-growing natural lashes — strong curls will over-rotate and look unnatural
Curl Types Explained
B Curl — Very Subtle Lift
Best for clients with naturally upward-growing lashes who want a barely-there enhancement. Rarely used as a primary curl — most commonly used at the inner corner of a mixed-curl set.
C Curl — Natural Lift
The most versatile and widely used curl. Suits almost every eye shape and creates a classic, natural lash extension look. The go-to curl for clients who want enhanced lashes without obvious drama.
CC Curl — Medium-High Lift
Sits between C and D. One of the most popular curls globally for hooded and Asian eye shapes as it creates visible lift without appearing overly dramatic. The recommended default curl for most artists.
If your client's extensions look flat or disappear when their eyes are open, upgrade from C to CC. This is especially common with hooded eyes where the lid fold covers the base of the extension. CC curl clears the fold and remains visible throughout the day.
D Curl — High Lift
Creates a strong upward lift and open-eye effect. Go-to curl for glamorous, wide-awake looks and volume sets. Recommended for monolid and deeply hooded eyes where CC curl still disappears behind the lid.
L Curl — Very High Lift
Flat base with a sharp upward curve at the tip. Ideal for clients whose natural lashes grow straight down or forward — the flat base sits flush against the natural lash regardless of growth direction, then curves sharply upward for maximum visible lift.
L+ Curl — Extreme Lift
Maximum drama. Best for editorial and cosplay looks, anime-style lash sets, or clients with severely downward-growing lashes who need extreme correction.
M Curl — Flat Base, Outward Then Upward
Similar to L curl but with a more gradual outward-then-upward curve. Ideal for lashes that grow straight forward (not downward). Creates a natural-looking lift without the sharp angle of L curl. Particularly effective for monolid and hooded eyes.
C curl on a monolid or deeply hooded eye will disappear completely behind the lid fold when the eyes are open. The client will see no visible extension. Always use CC or D curl as a minimum for these eye shapes — and consider L or M curl if the natural lashes grow downward or straight forward.
Curl by Eye Shape
| Eye Shape | Recommended Curl | Why |
|---|---|---|
| Almond | C / CC | Enhances natural shape without over-correcting |
| Hooded | CC / D | Lifts extensions above the hood for visibility |
| Monolid / Asian | CC / D / L / M | Creates open-eye effect above the flat lid |
| Round | C / CC | Elongates without adding more roundness |
| Deep-set | B / C | Subtle lift — strong curls can look overdone or touch brow bone |
| Downturned | D / L | Counteracts the downward angle of the outer corner |
| Upturned | B / C | Natural lashes already lift — strong curls over-rotate |
Curl by Style
| Style | Base Curl | Spike/Accent Curl |
|---|---|---|
| Natural / Classic | C or CC | — |
| Wispy | CC | D (spikes) |
| Volume | CC or D | — |
| Anime / Spike | D | L+ (spikes) |
| Mega Volume | D or CC | — |
| Hooded / Monolid Lift | D or M | L (outer corner) |
Can I Mix Curls in One Set?
Yes — mixing curls is an advanced technique that creates dimension and corrects eye shape. Common combinations:
- Progressive lift: C (inner corner) → CC (centre) → D (outer corner) — creates a lifted, elongated effect
- Wispy volume: CC base lashes + D spike lashes — adds texture and drama to the spike tips
- Ultra-natural: B (inner corner) + C (rest of lash line) — for clients who want the most subtle enhancement
- Hooded correction: CC (inner) + D (centre-outer) + L (outer corner) — maximum lift where the hood is deepest
Stronger curls (D, L, L+) have a smaller base contact area with the natural lash, which can slightly reduce the adhesive bonding surface. To compensate:
- Use a slightly slower-cure adhesive to allow more working time for precise placement
- Apply the wrap technique — approach from below so the base wraps around the natural lash
- Ensure the natural lash is fully degreased before application — oils reduce bond strength on all curls, but especially on high-lift curls with reduced contact area

Frequently Asked Questions
Which curl is most popular?
CC curl is currently the most popular choice globally, offering a balance of lift and naturalness that suits most eye shapes. It is the recommended default for new artists building their first curl range.
Can I use D curl on almond eyes?
Yes, but it will create a more dramatic look. Great for clients who want a glamorous, wide-awake effect. For everyday natural looks on almond eyes, CC is usually the better choice.
What curl is best for downward-growing lashes?
L or M curl. The flat base sits against the natural lash regardless of its growth direction, then curves sharply upward for maximum visible lift. L curl is more dramatic; M curl is more gradual and natural-looking.
Does curl affect retention?
Indirectly. Stronger curls (D, L) have a smaller base contact area, which can slightly reduce the adhesive bonding surface. Compensate with the wrap technique and thorough degreasing before application.
How do I choose between CC and D?
If your client wants a lifted but wearable everyday look, choose CC. If they want maximum drama or have hooded/monolid eyes where CC still disappears behind the lid, choose D.
What is the difference between L and M curl?
Both have a flat base for downward or forward-growing lashes. L curl has a sharper, more dramatic upward curve at the tip. M curl has a more gradual outward-then-upward curve that looks more natural. Use L for maximum correction; use M for a softer lift on forward-growing lashes.
