Different Kinds of Lash Curls For Eyelash Extensions

Different kinds of lash curls for eyelash extensions

Because of the growing demand for eyelash extensions, there is a greater need for different variations to accommodate different eye shapes. Depending on the curl type, eyelash extensions come in a variety of styles. It’s important to remember that manufacturers may label their curls differently and have slight variations in overall curvature, but these variations are generally easy to distinguish across most manufacturers.

As a lash tech, here are the most common curls to be aware of when purchasing eyelash extension supplies:

B Curl

B curl lash extensions are simple but provide a bit of curl. Not too exaggerated and not too flat. The finished look is natural, with a soft curl. They are ideal for clients who have straight natural eyelashes that point straight or slightly upwards.

They are also used by lash artists for inner corner lashes. They are not suitable for clients with heavily drooping eyes or natural lashes.

C Curl

C curl lash extensions, also known as the common curl, have a curl that is similar to or identical to natural lashes. They are ideal for clients who have a slight curl in their natural eyelashes.

If your client has straight natural eyelashes, using C curl will give them a doll or open eye effect. Meanwhile, if your client’s lashes are slightly downward angled, a C curl will provide a slight lash lift effect.

However, if your client’s lashes are heavily angled downward, do not use C curl; instead, use a more pronounced curl. I recommend a CC or D curl.

CC Curl

A CC curl is a type of hybrid curl. It’s a happy medium between a C and a D curl. This curl starts with the same base as a C curl and ends with the dramatic flair of a D curl.

This curl is great for adding lift to the outer edges of your set, especially on clients with droopy or downward-looking eyes.

D Curl

D curls are more dramatic and have a visible curl. If your client’s natural lashes are straight or angled downward, D curl is the way to go.

When you use D curl lashes on clients who have natural lashes with a downward angle, it creates an open eye effect. When used on clients with natural lashes that are horizontally angled, it creates a lovely doll eye effect.

It is critical not to use D curl lash extensions on clients with upward angle natural lashes and hooded eyelids because it may poke your clients’ eyes (depending on the length you use).

J Curl

J curl lashes have the most natural curl on our list and are a must-have in your lash supplies. This is ideal for clients who have naturally straight lashes that point straight or upward. The J curl should be considered if your client wants an everyday natural look.

J curl lash extensions should not be used on clients who have heavily hooded angle natural lashes.

L+ Curl Lashes

On our list, L curl has the most curl. It has a flat base with a pronounced upward curl. It is best suited for clients who have deep-set eyes, hooded eyes, or droopy eyelids.

Add L+ curl lashes to your list of curl types to consider if your client wants drama. It also has the most noticeable eyelid lift effect.

However, do not use L+ curl on clients who have natural eyelashes with a downward angle.

Choosing an Eyelash Extension Style and Length

When determining the length and diameter (thickness) of the eyelash extensions, you must first consider the condition of your client’s natural eyelashes. A heavy set of unhealthy or brittle natural lashes will result in breakage. This is detrimental to your client’s natural eyelashes.

Here are some pointers to help you guide your client as their lash tech:


Clients frequently express a desire for long lashes. Clients’ natural eyelash conditions, on the other hand, will determine the best and most practical length to work with.

Remember that it is your responsibility to guide and explain to your clients why a particular length is better suited to the condition of their natural lashes. It is critical to protect your client’s natural lashes’ health and avoid premature fallout or damage to their natural lashes by selecting a length that will not interfere with their growth cycle.

You can choose lash extensions that are slightly longer than the client’s natural lashes for clients who have hooded or droopy eyelids. Because when they open their eyes, their eyelashes tend to hide under their eyelids.

Remember that the stronger the curl of the lash extensions, the shorter they will appear. Choose the length of your eyelash extensions based on the curl type you intend to use.

Diameter or thickness

The diameter you will use will be determined by the set your client wants. 0.15 extensions are used for classic sets (in special cases, 0.10), and 0.07, 0.05, or 0.03 extensions are used for volume sets.

There are a few factors to consider when choosing the diameter for volume: how full your client wants their set, the health of their natural lashes, and the number of extensions per fan. Clients with healthy lashes can support more weight and larger fans; however, fuller volume sets necessitate the use of thinner extensions, such as 0.03s.

For Classic Sets, you should compare the thickness of your client’s natural lashes to the thickness of your lash extensions. This is the most accurate method for determining and estimating the thickness or diameter of the eyelash extensions you will use for your client.

Lifestyle and preference

People are becoming more aware of the importance of staying active. Many people wonder if they can have eyelash extensions despite the fact that they always run, swim, or work out. The short answer is that they absolutely can!

It is your responsibility as a lash tech to explain to your clients that lash extensions are not as fragile as they believe. Make it a point to ask your clients what kinds of exercises they do and how frequently they do them. It is also your responsibility to inform them on how to care for their lashes after an application with the proper lash supplies so that their extensions do not become damaged and fall off prematurely.

For example, if a client likes to run, jog, hike, or do anything else that makes them sweat, it is critical to inform them that they should not get their eyelash extensions wet 24 to 48 hours after the application. After that, they can begin exercising as long as they remember to clean their eyelashes on a daily basis. Explain the significance of a daily aftercare routine.

DO NOT get your eyelashes wet for 24 to 48 hours after application if you are a swimmer. This is extremely important. And, whatever happens, make sure your clients don’t rub their eyes. To protect their eyes from irritation, they can wear goggles.

When selecting eyelash extensions, it is critical to consider your client’s lifestyle and preferences. Before giving any advice or beginning application, always consider their natural eyelashes.
