In this article, we’ll make clear on how to distinguish 10 different most common lash curls and how a lash factory like us create each of them in our lash manufacturing.

1. J curl lashes

J curl lashes are a type of eyelash extension characterized by their straight base and slight curve at the tip, resembling the natural curl of many people’s natural lashes. This type of lash extension is considered one of the more natural-looking curls due to its subtle curve, making it ideal for clients who want to enhance their lashes without a dramatic effect. The angle that it’s created is about 30-35 degree, slightest one among all of the lash curls.

Key Features of J Curl Lashes:

• Natural Look: J curl lashes are perfect for those who want a natural enhancement. The slight curl mimics the natural shape of most lashes, providing a subtle lift and length without being overly noticeable.
• Straight Base: These lashes have a straight base, which makes them less dramatic compared to other curl types like C or D curls. The straight base allows for more contact with the natural lash, which can make them more secure and longer-lasting.
• Gentle Lift: The subtle curl provides a gentle lift to the lashes, making them ideal for clients with naturally straight or slightly downward-pointing lashes. They help open up the eyes slightly but are not as lifting as C or D curls.
• Versatility: While J curls are primarily chosen for a natural look, they can be combined with other curl types in a mixed set to create customized lash styles that suit individual eye shapes and preferences.

Best for:

• Clients Looking for a Subtle Enhancement: If someone wants their lashes to look longer and fuller without a noticeable curl, J curl lashes are a great option.
• Natural Lash Mimicry: They are ideal for mimicking the natural lash shape, especially for those with naturally straight lashes.
• Mature Clients: J curl lashes are often recommended for older clients who prefer a more conservative and understated lash look.

Considerations:

• Less Dramatic: If a client wants a more dramatic or noticeable lash look, they might prefer other curl types, such as C or D curls.
• Not Ideal for Curly or Downward-Pointing Lashes: For clients with very curly or downward-pointing natural lashes, J curls may not provide enough lift or may appear too straight.

2. B curl lashes

B curl lashes are a type of eyelash extension that offers a moderate curl, slightly more pronounced than J curl lashes but still relatively natural-looking. B curl lashes provide a balance between natural enhancement and a noticeable lift, making them a versatile choice for various lash styles and client preferences. The angle that it’s created is about 35-45 degree.

Key Features of B Curl Lashes:

• Moderate Curl: B curl lashes have a gentle curve that is more noticeable than the J curl but less dramatic than the C or D curls. This moderate curl helps open up the eyes while still maintaining a natural appearance.
• Natural Enhancement: These lashes are designed to enhance the natural lashes without creating an overly dramatic look. They add a slight lift and volume, making the eyes appear more awake and defined.
• Suitable for Most Eye Shapes: B curl lashes work well with most natural lash types and eye shapes. They are particularly good for clients with naturally straight or slightly curly lashes who want a bit more curl without going too dramatic.
• Subtle Lift: The B curl provides a subtle lift to the lashes, which can help open up the eyes and make them appear larger. This makes them a popular choice for everyday wear or for those who prefer a more understated look.

Best for:

• Clients Seeking a Natural but Noticeable Enhancement: B curl lashes are ideal for those who want a bit more curl than the J curl provides but still want to maintain a natural look.
• Clients with Naturally Straight or Slightly Curved Lashes: These lashes are great for clients whose natural lashes are straight or only slightly curved, as the B curl adds a bit more definition without being too bold.
• Everyday Wear: The moderate curl makes B curl lashes a versatile choice for everyday wear, as they enhance the lashes without appearing too dramatic.

Considerations:

• Less Curl for Very Straight Lashes: While B curls offer more lift than J curls, they may not provide enough curl for clients with very straight or downward-pointing lashes who want a significant lift.
• Not for Dramatic Styles: If a client desires a more dramatic or noticeable lash look, such as a glamorous or high-impact style, C or D curls might be a better fit.

3. C curl lashes

Among all the lash curls, C curl is one of the most popular types of eyelash extensions due to their noticeable, yet still natural-looking curl. They provide a more dramatic lift compared to J and B curls, making them ideal for clients who want their eyes to appear more open and their lashes more prominent. The angle that it’s created is about 55-60 degree.

Key Features of C Curl Lashes:

• Pronounced Curl: C curl lashes have a stronger curl than J and B curls. The curl resembles the natural curve of most eyelashes but with an added lift, which makes the eyes appear larger and more awake.
• Enhanced Lift: The C curl provides a significant lift to the lashes, making them ideal for clients who want their eyes to stand out without looking too exaggerated. This curl is perfect for creating a more alert, open-eyed look.
• Versatility: C curl lashes are versatile and can be used to create various lash styles, from natural to more glamorous. They work well for clients who want a noticeable enhancement without going too extreme.
• Good Adhesion: Due to their shape, C curl lashes have a better base-to-lash connection than some more dramatically curled lashes. This can result in a secure bond with the natural lashes, potentially leading to longer retention.

Best for:

• Clients Looking for Noticeable Lift: C curl lashes are perfect for those who want their lashes to be visibly curled and more defined than natural lashes.
• Clients with Straight or Slightly Curved Lashes: They are particularly suitable for clients with straight or slightly downward-facing natural lashes, as the C curl helps lift and enhance the appearance of the eyes.
• Everyday and Special Occasions: The moderate yet noticeable curl makes them a great choice for everyday wear and special occasions, as they provide a balanced look that is both elegant and natural.

Considerations:

• May Appear Less Dramatic on Downturned Eyes: While C curl lashes are good for lifting straight lashes, they may not be as effective for clients with very downturned eyes or lids, as the lift may not be as noticeable.
• Not Ideal for Very Curly Lashes: For clients with naturally very curly lashes, C curl extensions might not blend well and could appear uneven or mismatched.

4. CC curl lashes

So called C+ curl, CC curl lashes are a type of eyelash extension that provides a more dramatic curl than the standard C curl but is not as extreme as the D curl. They are designed to create a noticeable lift and curl, making them an excellent choice for clients who want their lashes to have a more pronounced, glamorous look without going too bold. The angle that it’s created is about 65 degree.

Key Features of CC Curl Lashes:

• Enhanced Curl: The CC curl offers a curl that is more pronounced than the C curl but slightly less than the D curl. This makes it ideal for clients who want more drama than what a C curl provides but not as intense as a D curl.
• Lifts and Opens Up the Eyes: Due to the increased curl, CC curl lashes are great for lifting the lashes and opening up the eyes, giving a more awake and alert appearance. This curl can help create a more youthful and wide-eyed look.
• Versatility in Style: CC curl lashes are versatile and can be used to create various lash styles, from slightly natural to full glam. They are ideal for clients who want a noticeable enhancement but still want the flexibility to wear their lashes for everyday looks or special occasions.
• Good Adhesion: The curl of the CC lashes provides a good balance between dramatic effect and lash retention. They offer a decent surface area for attachment to the natural lashes, helping ensure a secure bond.

Best for:

• Clients Seeking a Moderate to Dramatic Enhancement: CC curl lashes are perfect for those who want a significant lash lift and curl, making their eyes appear more open and their lashes more defined, without being as extreme as D curl lashes.
• Clients with Slightly Downturned or Straight Lashes: These lashes are suitable for clients with natural lashes that are straight or slightly downturned, as the CC curl helps lift the lashes upward, enhancing the overall appearance.
• Glamorous Looks: Ideal for clients who want their lashes to stand out, whether for everyday wear with a bit more flair or for special events where a more dramatic look is desired.

Considerations:

• Can Appear Too Bold for Some: While not as dramatic as the D curl, the CC curl is still quite pronounced. Clients seeking a subtle, natural enhancement might find this curl too intense for their preference.
• Not Ideal for Very Curly Natural Lashes: Clients with naturally very curly lashes might find that CC curls don’t blend as seamlessly, potentially leading to a mismatch in curl patterns.

5. D curl lashes

Along with C curl, D curl is also one of the most popular lash curls used. It’s a type of eyelash extension known for their dramatic, bold curl. They have a deep, prominent curl that creates a striking, lifted effect, making them a popular choice for clients who want a glamorous and eye-catching lash look. D curl lashes are ideal for achieving a wide-eyed, doll-like appearance. The angle that it’s created is about 70 degree.

Key Features of D Curl Lashes:

• Dramatic Curl: D curl lashes have a very pronounced curl that curves sharply upward, making them one of the most dramatic lash curls available. This curl gives the lashes a noticeable lift and creates an impactful look that draws attention to the eyes.
• Intense Lift: The deep curl of D curl lashes significantly lifts the lashes, making the eyes appear larger and more open. This effect can help achieve a more awake and youthful appearance, particularly for those with naturally straight or downward-pointing lashes.
• Ideal for Creating Volume and Fullness: D curl lashes are great for adding both volume and length. Their dramatic curl and lift create the illusion of thicker, fuller lashes, making them perfect for creating a bold, glamorous look.
• Suitable for Various Lash Styles: These lashes can be used to create various styles, from full glam to cat-eye effects, depending on the client’s preferences and natural lash line. They are particularly popular for events, photoshoots, and occasions where a more dramatic look is desired.

Best for:

• Clients Seeking a Bold and Dramatic Look: D curl lashes are ideal for clients who want their lashes to be the focal point of their makeup. They provide a high-impact, glamorous effect that makes the eyes stand out.
• Clients with Straight or Downward-Pointing Lashes: These lashes are particularly effective for lifting straight or downward-pointing natural lashes, helping to open up the eyes and create a more lifted appearance.
• Special Occasions: Due to their dramatic effect, D curl lashes are often chosen for special events, weddings, parties, and any occasion where a more striking lash look is desired.

Considerations:

• May Not Suit All Eye Shapes: While D curl lashes can be flattering on many eye shapes, they may not be the best choice for clients with deep-set eyes, as the intense curl can sometimes create a “closed off” effect.
• Not Ideal for Naturally Curly Lashes: Clients with naturally very curly lashes may find that D curl lashes do not blend well with their natural curl, leading to a mismatched or uneven appearance.
• Can Be Too Intense for Some: D curl lashes are quite dramatic and may not be suitable for clients seeking a subtle, natural enhancement. They are best for those who are comfortable with a bold lash look.

6. DD curl lashes

DD curl lashes, also known as “U curl” or Double D” curls, are a type of eyelash extension that offer an even more dramatic curl than D curl lashes. They have an extreme upward curl that creates a very lifted, bold, and eye-catching effect, making them ideal for clients who desire a striking, glamorous lash look. The angle that it’s created is about 80 degree.

Key Features of DD Curl Lashes:

• Extremely Dramatic Curl: DD curl lashes have the most pronounced curl of all lash types. The curl curves sharply upward, creating a very lifted effect that opens up the eyes significantly and gives a bold, intense look.
• Maximum Lift: The DD curl provides maximum lift to the lashes, making the eyes appear much larger and more awake. This curl is particularly effective for achieving a dramatic, doll-like appearance and is often used in creating highly glamorous lash styles.
• Enhanced Volume and Fullness: Because of their intense curl, DD curl lashes give the illusion of added volume and thickness. They are perfect for clients who want their lashes to look fuller and more voluminous, creating a bold statement with their lash extensions.
• Ideal for Special Occasions and High-Impact Looks: DD curl lashes are often chosen for events, photoshoots, or occasions where a dramatic lash look is desired. They are popular in the fashion and beauty industries for creating high-impact looks that draw attention to the eyes.

Best for:

• Clients Who Want a Bold and Dramatic Look: DD curl lashes are perfect for those who want a very noticeable lash look with an extreme curl. They provide a striking effect that makes the eyes the focal point of the face.
• Clients with Straight or Downward-Pointing Lashes: These lashes are especially beneficial for lifting straight or downward-pointing natural lashes, helping to open up the eyes and create a more alert, awake appearance.
• Special Occasions: Due to their bold, dramatic appearance, DD curl lashes are often chosen for special occasions, such as weddings, parties, photoshoots, or any event where a high-impact look is desired.

Considerations:

• Requires Careful Application: Due to their intense curl, DD curl lashes require precise application to ensure they adhere well to the natural lashes and maintain a uniform appearance.
• May Not Suit All Clients: The extreme curl of DD curl lashes may not be suitable for all clients, especially those seeking a more natural enhancement. They are best suited for those who are comfortable with a very bold lash look.
• Not Ideal for Naturally Curly Lashes: For clients with naturally very curly lashes, DD curl extensions may not blend well, potentially creating a mismatched appearance.

7. L curl lashes

L curl lashes are a unique type of eyelash extension that combines a straight base with a dramatic upward curl at the tip. This shape is specifically designed to create a natural lift and open up the eyes, making them particularly useful for clients with certain eye shapes or those who wear glasses.

Key Features of L Curl Lashes:

• Straight Base with Sharp Curl: The L curl starts with a straight base that transitions into a sharp upward curl at the tip. This distinctive shape makes the lashes appear more lifted while still providing the illusion of length and volume. The sharp curl helps mimic the natural growth pattern of straight lashes, creating a more seamless blend with the natural lash line.
• Enhanced Eye Opening Effect: The sharp upward curl of L curl lashes helps to open up the eyes, making them appear larger and more awake. This curl is especially effective for creating a more alert, youthful appearance without the need for overly dramatic curls that might look unnatural on some eye shapes.
• Ideal for Certain Eye Shapes: L curl lashes are particularly suitable for clients with hooded, monolid, or deep-set eyes. The straight base ensures that the lashes do not press against the eyelid, while the upward curl helps prevent the lashes from touching or rubbing against glasses or sunglasses.
• Natural Appearance: Despite their unique shape, L curl lashes can provide a natural-looking enhancement, especially when used on clients with straight or downward-facing natural lashes. The curl is less rounded than C or D curls, providing a lift that is noticeable but not overly dramatic.

Best for:

• Clients with Straight or Downward-Facing Lashes: The L curl helps lift and curl straight or downward-facing lashes, giving them a more open and lifted appearance.
• Clients with Hooded or Monolid Eyes: The L curl’s sharp upward angle is excellent for lifting the lashes away from the eyelid, making it ideal for clients with hooded or monolid eyes who want to create the illusion of more prominent, open eyes.
• Clients Who Wear Glasses: Because of the straight base and upward curl, L curl lashes are less likely to brush against glasses or sunglasses, making them a practical choice for clients who wear eyewear.

Considerations:

• Less Natural for Some Clients: For those with very curled or naturally voluminous lashes, L curl lashes might look less natural due to their unique shape. Clients seeking a subtle enhancement might prefer curls that follow a more traditional curve.
• Not Suitable for All Eye Shapes: While L curl lashes are great for certain eye shapes, they may not be as flattering on clients with naturally curly lashes or those with a strong natural curl, as the straight base might not blend seamlessly.
• Application Technique: L curl lashes require careful application to ensure that the base aligns well with the natural lash line, and the curl is positioned correctly to achieve the desired lift and effect.

8. M curl lashes

M curl lashes are a type of eyelash extension characterized by their unique shape, which features a sharp bend at the base and a more gradual curve through the rest of the lash. This distinctive design creates a bold, lifted appearance, making M curl lashes ideal for clients seeking a dramatic and eye-opening effect.

Key Features of M Curl Lashes:

• Sharp Bend at the Base: M curl lashes start with a pronounced, sharp bend right at the base of the lash. This initial angle helps to lift the lashes dramatically from the lash line, providing a striking lifting effect.
• Gradual Curve Through the Length: After the sharp bend, M curl lashes have a more gradual, elongated curve compared to other lash types. This design mimics the natural arc of the eye, enhancing the eye’s shape while providing a pronounced lift.
• Bold, Dramatic Appearance: The combination of a sharp bend and a gradual curve gives M curl lashes a unique look that is both bold and sophisticated. They create a noticeable lift that opens up the eyes significantly, making them appear larger and more defined.
• Suitable for Various Lash Styles: M curl lashes are versatile and can be used to create a range of styles, from a natural enhancement to a more voluminous, dramatic look. They are particularly effective for adding both length and lift, making them ideal for clients looking to accentuate their eyes.

Best For:

• Clients with Straight or Downward-Pointing Lashes: M curl lashes are excellent for lifting straight or downward-pointing natural lashes. The sharp bend at the base helps to lift the lashes away from the eye, creating an open, wide-eyed look.
• Clients with Hooded or Deep-Set Eyes: The unique shape of M curl lashes is especially flattering for clients with hooded or deep-set eyes. The sharp bend helps to lift the lashes away from the lid, preventing them from being hidden by the natural fold of the eyelid.
• Clients Seeking a Bold, Dramatic Look: M curl lashes are perfect for clients who want their lashes to stand out. The distinctive shape provides a dramatic effect that is ideal for creating high-impact, glamorous lash styles.

Considerations:

• Can Look Less Natural on Some Clients: Because of their bold shape, M curl lashes can appear less natural on clients seeking a subtle enhancement. They are best suited for those who are comfortable with a more dramatic lash look.
• Not Ideal for All Eye Shapes: While M curl lashes are versatile, they may not be suitable for all eye shapes. Clients with naturally very curly lashes or those with a strong natural curl may find that M curl extensions do not blend well with their natural lashes.
• Requires Skilled Application: Due to the sharp bend at the base, M curl lashes require precise application to ensure they adhere correctly to the natural lashes. The unique shape can be challenging to apply, so it’s important for lash artists to have experience working with this type of curl.

9. LC curl lashes

LC curl lashes are a specialized type of eyelash extension designed to offer a unique combination of characteristics from both L curl and C curl lashes. They are known for their versatility in creating various looks, particularly suited for clients with specific lash needs or those seeking a distinctive eye-opening effect.

Key Features of LC Curl Lashes:

Considerations:

• Not as Dramatic as Other Curls: While LC curl lashes offer a noticeable lift, they are less dramatic than curls like D or DD curls. Clients seeking a more intense, eye-catching look might find LC curls less bold.
• Requires Precise Application: The combination of straight base and gentle curl requires careful application to ensure the lashes adhere correctly and achieve the desired effect. Proper technique is important to maintain the natural-looking lift and curl.

10. LD curl lashes

LD curl lashes are a type of eyelash extension that combines elements of both L curl and D curl lashes. They are designed to offer a distinctive look that provides a dramatic lift while maintaining a more natural appearance compared to the most extreme curl types. Here’s a detailed look at LD curl lashes:

Key Features of LD Curl Lashes:

Considerations:

• Compatibility with Natural Lashes: Clients with naturally very curly lashes might find that LD curl extensions do not blend as seamlessly, as the straight base may not align well with their natural curl pattern.
• May Require Skilled Application: The combination of a straight base and dramatic curl requires precise application to ensure that the lashes adhere correctly and achieve the desired lift and volume. Proper technique is crucial for maintaining the natural-looking effect.
• Not as Extreme as Some Other Curls: While LD curl lashes offer a dramatic look, they may not be as extreme as the most pronounced curls like DD or U curls. Clients seeking the most intense curl might find LD curls less bold.

How are the lash curls created in our production?

To create the lash curls in prouduction, we use lash curler. However, the curler here is not the same as one used by clients with strips lashes. Our lash curler is actually a tube with its defined demension.

The combination between the Demension of the tube and the length of the lash will create the right curl that we want. So the key here is selection the right tube with the right demension for each case of lash curl and length.

• The right curl = the right α = the right β . (We know that β=2α)

• D = L/π x 180/α

Note: The length of the lash base should be deducted from the whole length of the lashes because what we need is the right angel after application on the eyes.

With special lash curls, we just simply use the tube with the shape of the wanted curl.

This video can show you better.

Hope that this post can help you have a better understanding about the lash curl and how we make it in production. The message that we would like to deliver here is:

“We can supply all of the lash curls above. And We can adjust any of them as you wish. It means that if you still want C curl, but a little bit more bended, just tell us”
