How to choose the most suitable curl

Selecting the perfect lash curl involves considering factors like natural lash characteristics, such as eye shape and lash angle, alongside client preferences. The chosen curl significantly affects lash volume and overall appearance, making it essential to align the curl choice with individual features and desired looks.

1. Based on eye shapes

Monolid Eyes:

When working on those charming monolid eyes, try a blend of B, L, and C curls. This combo creates depth and widens the eyes, offering a balanced enhancement without overwhelming the natural shape.

Hooded Eyes:
For your clients with hooded eyes, aim to lift and elongate their lids with L and C curls. These curls work like magic, opening up their gaze for a larger and dreamier look. Remember, steer clear of D or DD curls for this eye shape.

Upturned Eyes:
To maintain the natural lift of upturned eyes, stick with J or B curls. They preserve that beautiful curve without exaggerating it, giving a subtle yet charming touch to their eyes.

Downturned Eyes:
Let's uplift those downturned eyes! Use curls like C or CC to give the illusion of lifted eyes, creating a brighter and more open appearance.

Round Eyes:
For clients with round eyes, go for curls that elongate them. Avoid B, C, D, and L curls for this look as these curls will negatively make your clients’ eyes even bigger and rounder, possibly making them look startled.

Almond Eyes:
Almond-shaped eyes? They are the most common eye shape that can pull various lash styles. For this easy-going eye shape, opt for curls based on the desired looks that they choose.

Narrow Eyes:
Widen and enhance narrow eyes with C or CC curls. These curls offer an eye-opening effect without overwhelming the natural shape.

Wide-Set Eyes:
For that captivating doll-eyed effect, use curls like C, D, and L. They balance the eyes without adding excessive width.

Close-Set Eyes:
Highlight natural angles and widen close-set eyes with B or C curls. They offer a flattering, well-balanced look that suits this eye shape.

Protruding Eyes:
Minimize protrusion with subtle C or CC curls. Avoid overly dramatic curls like D or DD to focus on enhancing their eyes.

Deep-Set Eyes:
Gently open up those mesmerizing deep-set eyes with L or M curls and longer bases. These curls enhance eye shape without overpowering it, creating a harmonious look.

2. Based on Lash Angle

There are three primary angles: downward, straight, and upward. Each angle demands specific attention to achieve a natural look while ensuring optimal retention.

Downward Lashes:

When working with downward angled lashes, prioritize curls like L and M. Their long flat base ensures a secure bond and a natural lift. While curls such as C and D are an option, their shorter bases may reduce retention, create a visible gap between the extension and natural lashes, leading to an artificial appearance. Avoid using subtle curls J or B here as they can weigh down the eyes, making them appear smaller.

In contrast, the D curl, despite its dramatic curve, exhibits a significant gap between extensions and natural lashes, resulting in an unnatural appearance and reduced retention. Emphasizing the importance of considering multiple factors when selecting lash curls for clients to achieve stunning, enduring lash sets

Straight Natural Lashes:

Straight lashes offer versatility but require careful consideration. Curls like J, B, and even the dramatic ones (C, CC, D, or DD) are viable options. However, be mindful to choose the closest curl as too much curl can create a big gap, leading to poorer retention and an unnatural appearance when viewed from the side.

Upward Lashes:

For clients with upward angled lashes, opt for subtle curls like J and B for a natural, open-eye effect. Avoid using M, L, or excessively dramatic curls. Their minimal contact points might cause retention issues, and the visible gap could cause natural lashes to protrude underneath.


Remember, each eye often exhibits different angles, and there's also a mix of angles within one eye. This requires lash techs to be flexible and strategically choose curls that match those diverse lash angles, creating a harmonious and perfectly balanced look for the overall lash set.

3. Based on Desired Styles or Look

Natural look: The J and B C curls are perfect for those seeking a subtle enhancement. They provide just a hint of a curl, ideal for a more understated, everyday appearance.

Glam look: Sometimes, it's all about that extra drama or making the eyes appear larger. Here's the trick—more curls! Flexibly mix CC, D, and DD curls to achieve that heightened effect. They're perfect for special occasions or when you want to make a statement with your eye makeup.

Doll-Eye Style:
When your client yearns for wide, doll-like eyes, it's all about opening up their gaze. A blend of ultra-curled lash extensions such as D and DD curls adds that captivating doll-eye allure, enhancing their natural beauty.

Cat-Eye Style:
For clients with smaller eyes aiming for a feline-inspired look, incorporating a range of curl mixes is the key. Start with versatile curls like C and gradually move up to D. Don't hesitate to include DD curls for added drama. This style elongates the eyes, creating a sexy cat-eye effect that complements smaller eye shapes perfectly.


4. Based on Retention

Retention varies with curl types. Generally, curlier lashes have shorter retention due to less contact area. Choose the right combination of curl and thickness for optimal retention aligned with your client's natural lashes.

Tips for Lash Artists and Technicians

During consultations, keenly assess your clients' needs by engaging in active listening. Understand their expectations, lifestyle, and desired outcomes to suggest the most suitable lash curls. Prioritize their comfort and desired style while recommending lash curls that complement their eye shape and natural lashes, ensuring a personalized and satisfying experience.
