There is a wide selection of options and lash extension styles, and we help you to choose the right kinds of eyelash extensions from BL lash collection.  


What are eyelash extensions made of?

Most of the lash extensions are made of a synthetic material called PBT, in our case, of high-quality Korean PBT. 

 We have some very informative posts about different types of eyelashes available, find them here:

Different types of Lash Extension Curls 

Listen, here is a fact. All lash extension curls exist in the market except J and C curl was initially invented by BL Lashes. As a result, we have the broadest range of curls to offer. We believe that having a variety of curls in your salon will enable you to serve your clients tailor to their eye shape and desired style. 

Eyelash Extension Curls and Lash Design

Curls of lash extensions set the overall appearance of the eyes, and the correct use of curls can even enhance the client's natural eye shape. No one curl fits for all.

When it comes to choosing the lash extension curl, it is vital to set a goal of what style you are trying to achieve for the particular client's eye shape, natural lash's angle, and characteristics.



Curls and retention

Sadly not all curls will have the same retention. The curlier the lash offers less retention because there is less of the base to attach to. So it is essential to choose the right combination of curl and thickness of extensions according to your client's natural lash.


lash extension charts by bl and blink lashes - eyelash extension supplies and wholesale


I Curl lashes

Less known curl, I Curl eyelashes are almost straight looking curl, and they can be used for the male clients who want to enhance the thickness of their lash but not necessarily want to have them curled.


J Curl lashes

J Curl eyelashes are the most natural-looking curl. These lashes are especially suitable for the clients who have stick straight lashes pointing straight or upward. If you apply J curl to the downward-looking natural lash, it will make the eyes look smaller and heavy. 


B Curl lashes

B Curl lash extensions will give the straight natural lashes a bit more "lift" than J curl. B curl has a bit more curl than a J curl but is still an excellent option for the clients with straight lashes, pointing straight or upward. 

B Curl lashes offer a soft curl, a standard for a naturally enhanced lash appearance with excellent retention.


L and L+ Curl lashes

L and L+ Curl are essentially C or D curls with a flat base. Because of the flat base, you will be able to give your client the ultimate eyelid lift. We developed L and L+ Curl to provide a wide-eye effect to the clients with hooded eyelids, deep-set eyes, older clients with droopy eyelids. L+ is slightly curlier than L. 

These are the most visually rewarding lash extensions. However, because of their long flat base, if used on downward-angle lashes, they will appear to be heavy and unflattering. 


M Curl lashes

M Curl gives the opposite effect to what J curl does. Its shape being with a small surface for the flat base and dramatic curl upwards, M curl is designed to lift the appearance of downward-angled natural lashes. Because of the dramatic upward angle, you will be able to give a lash lift and wide-eye effect. 

We do not recommend M Curl for clients with hooded eyelids or upward angled natural lash. 


C Curl lashes 

We designed C Curl lashes for clients with a slight curl in their natural lash, and they create an open-eye effect. 

C Curl is the most popular curl; it is glamorous and opens the eye. If you apply C curl to the client with slightly downward angled lashes, it will give a satisfying lash lift, if used for the client with close-to-horizontal angle lashes, it will provide a fabulous doll eye effect.

If your client has heavily downward-angled lashes, we recommend using D curl instead. 


D Curl lashes (also known as CC Curl)

D Curl lashes are very similar to C Curl lash extensions, just curlier. They are especially useful for clients with downward-angled lashes who want a show-stopping look. These lashes will brighten and widen the eye and give a noticeable curled effect. 

Because of its dramatic upward curl, if used for clients with upward-angle natural lashes or with heavily hooded eyelids, the extensions may prick the client's eyelids. For that reason, D curl is more suitable to the clients with downward-angle natural lashes.

It's one of the curlier curls, if not applied correctly, retention may not be as great as you would gain with straight curls, but D curl adds drama and opens the eye more, making it excellent for downward-angled lashes. 


U Curl lashes (also known as DD Curl)

U Curl lashes are the curliest lash extensions. They are suitable for clients with downward-angled lashes who want the most dramatic doll-like eyelashes. These lashes will give a noticeable curled effect. 

Just like D curl, because of its dramatic upward curl, if used for clients with upward-angle natural lashes or heavily hooded eyelids, the extensions may prick the client's eyelids. For that reason, U curl is more suitable for a client with downward-angle natural lashes.


BL EZ Curl lashes

The base curl of our EZ lash is straighter than the regular extension lashes. As a result, EZ lash provides more adhesive area for extensions and allows a much easier extension experience for beginner lash artists. 

Thanks to its wider adhesive area, EZ curl lashes also provide better retention. However, because of their long flat base, if used on downward-angle lashes, it will appear to be heavy and unflattering. 


Eyelash Extension Size Chart and Guidelines

Thickness (Diameter)

Choosing the right diameter of the eyelash extensions for our clients is critical. When deciding the thickness of the lash, you should not only consider the design aspect but, most importantly, your client's natural lash condition. Some thicker extensions (above 0.20, for example) can be too heavy for some clients' natural lash. A wrong choice could cause poor retention and premature fall of the extensions.

Generally, Asian's natural eyelashes are thinner than other ethnicities. For Asian clients, it is recommended to use lash extensions diameter between 0.10~0.15mm, whereas other ethnicities with stronger natural lashes can take 0.15~0.20mm for the classic extension. 

However, regardless of the ethnicity of the client, you should always take a good look at the client's natural lashes and decide what thickness is suitable for the client.

0.03mm, 0.05mm and 0.06mm diameter lashes

The popular thickness for Russian Volume for 2D~6D.

0.07mm diameter lashes

0.10mm diameter lashes

This thickness can also be used for Volume 2D~3D (depending on the natural lash thickness and length) or as Classic 1D on thinner, very fine natural lashes.

0.12mm diameter lashes

Used on thinner lashes (Classic 1D) or for a softer wispier look and feel.

0.15mm diameter lashes

This is the most popular, average lash thickness, creates a naturally thicker look (Classic 1D).

0.18mm diameter lashes

This lash extension thickness creates a slightly bolder look than 0.15mm lash.

0.20mm diameter lashes

The second most popular thickness for the classic extension. This lash extension thickness creates a natural mascara look. Recommend using for thick and healthy natural lash only.

0.25mm diameter lashes

This extension creates a glamorous look, though this lash may be too heavy for most people's lashes.

0.30mm diameter lashes

For healthy, strong, thick natural lashes. Creates an extreme look –though, might be too heavy for most people's lashes.


Eyelash Extension Lengths

BL lash extensions come in lengths from 5mm-20mm. 

The majority of clients want their longest extension length to be around 11mm or 12mm. Naturally, many customers want the longest lashes, but it is essential to keep in mind that the individual client's lash condition should determine the length of the extension. It is your responsibility to guide your client that the lashes too long for the natural lash may cause a premature fall of extensions.

Choose slightly longer lashes for the clients with hooded eyelids, or droopy eyelids. Their lashes tend to 'hide' under the eyelids when the eyes are open.  

When using the curlier curls like D, U curl, remember when the curl is strong, the length of the extension will appear shorter. So choose the lash length accordingly to the curl you are using.

Eyelash Extension Supplies Part 2: Eyelash Extension Glue

What is lash glue made of?

Typical components of eyelash extension adhesive are as the following:

  • 90~95% of Cyanoacrylate
  • 5~10% of Complex compounds such as stabilizer, thickener, hardening accelerator, colorant, etc.

NB! All types of eyelash extension adhesive use Cyanoacrylate, which is the only one-component that can be hardened under the circumstance genuinely.

There is no other substitute glue that can replace the retention and adhesion of the current eyelash extension adhesive. 


Which is the best eyelash extension glue from BL?

It is impossible to say which adhesive is the best because that is highly subject to the treatment environment, proficiency of the technicians, and preference of individuals.

You should decide what is the best glue for you by considering the room environment, speed of the procedure, and client's condition.

For example, if the technicians use a 1~2 seconds of fast-drying glue when their skill level actually take 3~4 seconds to apply extension lashes on natural lashes, then the retention will inevitably decrease. That happens because the extension lashes are applied to natural lashes after the glue is already a bit dried.

Another example would be if the technicians use the slow drying glue when their speed of procedure is faster than that, it is not an appropriate glue either, because it will slow down the lashing procedure.

What we can recommend is to ALWAYS adjust the room environment (humidity & temperate) to the ideal setting for the eyelash extension glues to perform more consistently. In this way, you'll soon find the best lash adhesive works for you.


Read more: Eyelash extension glue and humidity


We recommend: 

For Experts - Fast Drying Time: Mach Glue, DIU Glue

For intermediates - Medium Drying Time: Ultra X Glue, Ultra Plus Glue, Fina Glue

For Beginners - Slow Drying Time: Q-1, Ultra Bonding, Ulbon Glue

*The above-recommended glues are the guideline according to the drying time. We recommend you to make extra considerations based on your room humidity, temperature, preferred viscosity, and fume level.


Which eyelash extension adhesive is best for volume extensions?

Volume extension glues can be divided into two main categories:

  1. Adhesives for handmade volume lashes
  2. Adhesives for pre-made volume lashes

For handmade volume lashes, as you need to make a fan, it is recommended to use a fast-drying glue or the one that has a bit high viscosity. Mach Glue is suitable for those who are fast when applying extension lashes. Glam Glue is ideal for those who want an adhesive that has longer drying time and thicker consistency.

For pre-made volume lashes, we recommend using a glue that has fast drying time and low viscosity. This is because the adhesion parts of pre-made volume lashes are wide. Glue can be applied excessively on those wide areas, which will result in surrounded lashes sticking to them.

Mach Glue  is suitable for those who are fast when applying extension lashes. Ultra X Glue or Ultra Plus Glue, glue is ideal for those who want a glue that has a longer drying time.


How long is the expiration date (Shelf-life) of the adhesive?

3 to 6 months when not opened, one month once you have opened the bottle.

When the adhesive is contained in its bottle, it is hard to harden because the surface area that is in contact with the air is small.

However, once the adhesive is applied to the surface material like a jade stone, as the surface area becomes wider, the hardening reaction becomes active, and the whole area of the adhesive starts to harden.

Since the hardening of adhesive is always in progress (even when it's kept in the bottle), its potency keeps on deteriorating. That happens even if the glue bottle is not opened and used. The period from the moment it is manufactured to the state of unavailability to use is called the 'expiration date.'

It is important to keep the adhesive stored in the appropriate temperature and humidity and pay attention to the storage methods to prolong the expiration date.

Eyelash Extension Supplies Part 6: Under-Eye Pads & Tape

Under-eye patches/ eye pads/ under-eye masks

What are under-eye pads used for?

You need eye patches every time you do eyelash extensions. Eyelash gel pads secure the lower lashes tightly in place to allow for a clean and efficient application. 

Our under-eye skin is the most sensitive part of our skin, and eye patches protect it during the lash application process.

The shape of the gel pad contours perfectly to human eyes and provides a more soothing and relaxing experience than using a tape alone. The eye pads are packed with moisture and nutrients that freshen up the client's eyes and provide a pleasant and cooling effect.

BL Under-eye masks help improve wrinkles, dark circles, and puffiness around the eyes. You'll notice the difference right away - a visibly smoother, brighter, and more youthful appearance. With regular use, the results will last longer.

3M Plastic Tape offers an all-direction stretch and is water-resistant for maximum comfort. The thicker foam padding helps protect the accidental touching of lash tweezer tips to the face.

Glue Tape 

  • Keep glue dot fresh for much longer period
  • Suitable for handmade volume artists, new lash artists
  • Not to be used on the client's face
Why you should try this:

Extension glue drops on the rough surface will easily let moisture enter into the glue drop and lose its droplet shape and dry prematurely. 

BL Glue Tape helps eyelash extension glue to stay in its perfect droplet shape for a more extended period.

The special PE coating on the Glue Tape provides a much smoother surface area and blocks out moisture entering into the paper tape.

Our lab study shows the glue drops on BL Glue tape stay fresh and perfectly round for 20 minutes, whereas the glue drops on regular paper tape stay fresh for only 10 minutes.  

This is a great product, especially for the Russian Volume Lash Artists, who usually require a longer application time or new lash artists.
