In this blog, we will discuss eyelash extension adhesives in detail. From the different types of adhesives available to the factors to consider when choosing an adhesive, this article will provide you with a comprehensive guide to eyelash extension adhesives. Whether you're a professional lash artist or someone considering eyelash extensions, this blog will equip you with the knowledge to make an informed decision about the right adhesive for your needs.


Why is it important to choose the best eyelash extension adhesives? 


Eyelash extension adhesives play a crucial role in the success of eyelash extensions. Here are some of the reasons why lash adhesives are so important:


  1. Retention: The adhesive used to apply eyelash extensions is responsible for keeping the extensions securely in place. A high-quality adhesive will ensure that the extensions stay in place for the duration of the treatment, which is typically several weeks.
  2. Safety: The adhesive must be safe for use on the delicate skin around the eyes, and should not cause any irritation or adverse reactions. Poor-quality adhesives can cause damage to natural lashes, or even cause an allergic reaction.
  3. Comfort: A good adhesive will not only be safe but also comfortable to wear so that the wearer can go about their daily activities without any discomfort or irritation.
  4. Application: The adhesive used for eyelash extensions must have the right viscosity, or thickness, to make the application process easy and efficient for the lash artist. It must also have the right curing time according to the temperature and humidity of the room.


In summary, the importance of eyelash extension adhesives cannot be overstated, as they directly affect the safety, comfort, longevity, and overall appearance of eyelash extensions. Choosing the right adhesive is essential to ensure a successful and satisfying eyelash extension treatment.



How to Properly Store Lash Adhesives

Proper storage of synthetic eyelash extension adhesives is essential to ensure their effectiveness and longevity. Here are a few tips for properly storing synthetic adhesives:


  1. Store in a cool, dry place: Synthetic adhesives should be stored in a cool, dry place away from direct sunlight and heat. This will help to prevent the adhesive from breaking down and losing its effectiveness.
  2. Keep the lid tightly closed: After each use, it is important to close the lid of the adhesive bottle tightly to prevent air from entering and drying out the adhesive.
  3. Avoid extreme temperatures: Synthetic adhesives should not be stored in extremely hot or cold temperatures as this can cause the adhesive to break down and become less effective.
  4. Store in the original packaging: It is recommended to store synthetic adhesives in their original packaging, as this will provide proper protection and help to keep the adhesive in good condition.
  5. Nozzle Cleaning: Ensure you are cleaning the adhesive nozzle with a gauze wipe to prevent the lid from becoming stuck and the nozzle from being blocked


Temperature Range for eyelash extensions adhesive/lash glue


It is recommended to store and use lash adhesives in a room with a stable temperature between 18°C and 24°C (64°F and 75°F). This will help to ensure that the adhesive remains in good condition and retains its effectiveness for the duration of its lifespan.


What's the ideal temperature for eyelash adhesive?


Most eyelash extension adhesives perform best within a range of 20 – 22 degrees Celsius (68-72F)


Best humidity range for eyelash extensions adhesive/lash glue


The optimal performance of your synthetic eyelash extension adhesive depends on the conditions in which it is used. It is recommended to use the adhesive in conditions with a humidity level between 40-60% (as indicated in the product description and supplier guidelines). Rapid fluctuations in humidity levels can impact the curing process of the adhesive and affect retention, so it is important to be aware of and monitor the humidity levels in your work environment.


What's the ideal humidity for eyelash adhesive?


Most eyelash extensions adhesives/lash glues perform best within a range of 45 - 55 % humidity


What is the average shelf life of eyelash adhesives?


It is important to take note of the shelf life of synthetic eyelash extension adhesives as it affects the effectiveness and safety of the product. Once a bottle of synthetic adhesive has been opened, it is recommended to use it within a maximum of 6 weeks. Using an adhesive that has been open for longer than 6 weeks may result in reduced effectiveness, increased risk of skin irritation or allergic reactions, and may not produce the desired results.



Top 10 Most Common Questions on Eyelash Adhesive / Lash Glues


What glue is used for eyelash extensions? 

Ethyl-cyanoacrylate adhesives are the most commonly used type of adhesive for eyelash extensions. These adhesives are waterproof, long-lasting, and quick-drying, making them ideal for bonding individual lashes to natural lashes. Ethyl-cyanoacrylate adhesives are known for their strong bonding properties and are favoured by many lash artists for their reliability and effectiveness. However, it is important to choose a high-quality ethyl-cyanoacrylate adhesive specifically formulated for eyelash extensions and to follow the manufacturer's instructions for safe and effective use.


Warning: It is important to never use adhesives other than those specifically formulated for eyelash extensions, such as ethyl-cyanoacrylate adhesives. Using other types of adhesives, such as nail glue, on the lashes can be extremely dangerous and can cause serious health and safety concerns. Nail glue is not designed for use on the eyes and can cause severe irritation, allergic reactions, and even permanent damage to the eyes and surrounding skin. In addition, using unapproved adhesives can also lead to a decrease in the quality and longevity of the eyelash extensions, and may result in a subpar final result. To ensure the health and safety of clients and lash artists, it is imperative to only use adhesives that are specifically formulated for eyelash extensions.


What is the difference between lash glue and lash adhesive?

Lash glue and lash adhesive are often used interchangeably to refer to the same thing, which is the substance used to bond individual lashes to natural lashes in eyelash extensions. Both terms refer to the same type of product and the difference between them is purely semantic. Essentially, both terms are used to describe the same type of product, which is a specially formulated adhesive designed for use in eyelash extensions. Whether referred to as lash glue or lash adhesive, it is important to choose a high-quality product such as Megan Thomas Platinum Range, that is specifically formulated for eyelash extensions and to follow the manufacturer's instructions for safe and effective use.


What is the best eyelash extension glue UK?

The best eyelash extension glue in the UK is subjective and depends on individual preferences and requirements. However, a few popular and highly-regarded options include the Megan Thomas Platinum lash glues range, London Lash Pro, and The Lash Collection Adhesives. These adhesives are well-known for their strength, longevity, and safety, and are favoured by many lash artists in the UK. When choosing an eyelash extension glue, it's important to consider the specific needs and requirements of your clients and to follow the manufacturer's instructions for safe and effective use. It may also be helpful to try a few different adhesives to find the one that works best for you and your clients.


Is dark or clear lash adhesive better?

The choice between dark and clear eyelash extension adhesive is mostly a matter of personal preference and the specific needs of your clients.


Dark adhesives, such as black or brown, can be ideal for clients with lighter lashes as they provide a more natural look by blending in with the natural lash line. This can help to create a more seamless and subtle look for the client.


Clear Ethyl-Cyanoacrylate (ECA) lash adhesives is a type of eyelash extension glue that is formulated without any pigments or other colouring agents. This makes it ideal for clients with sensitive eyes or allergies, as it contains fewer ingredients that could cause irritation or allergies. Clear ECA adhesive is also ideal for clients with darker lashes, or for those who prefer a more subtle look, as it provides a more natural appearance by blending in with the natural lash line.


Clear eyelash extension adhesives are a popular choice for Russian volume fans due to their strength and ease of use. These adhesives have a strong, fast-drying formula that helps to create a secure bond between individual lashes and natural lashes. The clear formula also makes it easier to see the lashes during the application process, allowing lash artists to create precise and uniform fans.


Clear lash glues have a thinner consistency compared to other adhesives, which can make them easier to work with when making Russian volume fans. This thinner consistency allows for more control and precision during the application process, resulting in a more polished and professional-looking final result.



Why is my eyelash extension glue not sticking?

There can be several reasons why your eyelash extension glue may not be sticking:

  1. Environmental conditions: Humidity, temperature, and air movement can affect the performance of your eyelash extension glue. If the humidity is too high, the glue may cure too quickly and not provide adequate retention. If the temperature is too low, the glue may take longer to cure and cause the extensions to droop. Air movement can also cause the glue to dry too quickly, making it difficult to apply the extensions.
  2. Improper storage: If your glue has been stored in an environment that is too hot or too cold, it may have lost its effectiveness and may not stick properly.
  3. Old glue: Eyelash extension glue has a shelf life and can deteriorate over time, making it less effective. If you have had your glue for a long time, it may be time to replace it.
  4. Incorrect application: If you are not applying enough glue or if you are not applying it evenly, the extensions may not stick properly.
  5. Incompatible products: If you are using a different type of product, such as oil-based products, on your lashes, it may interfere with the adhesive and cause it to not stick properly.


If you are having trouble with your eyelash extension glue not sticking, it may be helpful to try adjusting your environmental conditions, storing your glue properly, replacing old glue, practising proper application techniques, and avoiding incompatible products.


Why is my lash glue not coming out?

There can be several reasons why your lash glue may not be coming out:

  1. Clogged nozzle: If the nozzle of your glue bottle is clogged, the glue may not come out. You can try wiping the nozzle with a damp cloth or using a toothpick to clear the clog.
  2. Thickened glue: If your glue has been stored for a long time or has been exposed to high humidity, it may have thickened and become difficult to dispense.
  3. Cold temperature: If the temperature of your glue bottle is too cold, the glue may have thickened and become difficult to dispense.
  4. Air bubble: If there is an air bubble in the bottle, it may prevent the glue from coming out. You can try tapping the bottle to remove the air bubble.
  5. Incorrect storage: If your glue has been stored in an environment that is too hot or too cold, it may have lost its effectiveness and may be difficult to dispense.


In conclusion, proper storage and maintenance of your eyelash extension glue are essential to ensure optimal performance and longevity. Wiping the nozzle of your glue bottle after each use and using a pin to clear the nozzle can help prevent clogging and ensure the smooth flow of the glue. Additionally, it is important to replace your glue if it is over 6 weeks old from opening to ensure that it is still effective and safe to use.


If you are having trouble with your lash glue not coming out, try adjusting the temperature, clearing the nozzle, removing air bubbles, and storing the glue properly. If the problem persists, it may be time to replace your glue.


How to open a stuck eyelash glue bottle?

If your eyelash glue bottle is stuck, there are several methods you can try to open it:

  1. Warm up the bottle: Try running warm water over the bottle or using a hairdryer set to low heat to warm up the bottle and loosen the glue.
  2. Tap the bottom of the bottle: Try tapping the bottom of the bottle against a hard surface, such as a countertop, to loosen the glue and release the bottle cap.
  3. Use rubber gloves: Try using rubber gloves to grip the bottle and twist it open. The extra grip can help loosen the glue and open the bottle.
  4. Use a rubber band: Wrap a rubber band around the bottle cap and twist it open. The rubber band can help provide extra grip and loosen the glue.
  5. Use a tool: Try using a small tool, such as a pair of pliers or a wrench, to grip the bottle cap and twist it open.

If none of these methods work, it may be best to replace the glue bottle rather than risk damaging it or injuring yourself.


Why is lash adhesive not drying?

There could be several reasons why your lash adhesive is not drying:

  1. Humidity: High humidity levels can prevent the glue from drying properly. Make sure to use your adhesive in optimal conditions, usually between 40-60% humidity, as specified by the product description and supplier guidelines.
  2. Contamination: If the glue nozzle or the lashes have any oil or other contaminants, the glue may not adhere properly and will not dry. Always make sure that the lashes and the nozzle are clean and free from any oil or other contaminants before applying the glue.
  3. Improper storage: If the glue has been stored in a warm or humid place, it may have a shorter shelf life and not dry properly. Store your adhesive in a cool, dry place, away from direct sunlight and heat.
  4. Old glue: If the glue is over 6 weeks old from opening, it may have lost its effectiveness and may not dry properly. Consider replacing the glue if it is over 6 weeks old.
  5. Temperature: Extremely hot or cold temperatures can affect the performance of the glue. Make sure to use the glue in a temperature-controlled room.


What professional lash glue for beginners?

For beginners, it is recommended to start with a low-fume and slow-drying eyelash extension glue. This will give you more time to adjust the extensions and make any necessary corrections before the glue sets. Some popular options include:

  1. Megan Thomas Platinum Lash Glue
  2. NOVALASH Platinum Bond Adhesive
  3. Misencil Stable Adhesive

It is also important to remember that everyone's skin reacts differently to different adhesives. So, it's best to start with a small amount of glue and perform a patch test before using it on a client. It's also essential to store and use the adhesive properly to maintain its quality and effectiveness.



What professional lash glue for experts?

For experienced eyelash extension artists, it is recommended to use a strong and fast-drying adhesive that can withstand harsh conditions. Some popular options include:

  1. Megan Thomas Platinum Plus or Platinum Clear Lash Glues
  2. Borboleta Intense Bond Adhesive
  3. LashXO PRO Adhesive

These adhesives are formulated for experienced technicians and provide a secure and long-lasting hold. However, it's important to remember that the choice of adhesive ultimately depends on the individual client's skin type, the climate, and the application technique. As a professional, it's best to have a variety of adhesives on hand to accommodate different clients and conditions.



Should I wash my eyelashes after having eyelash extensions? 

Yes, it is recommended to wash your eyelashes after having eyelash extensions applied. This helps to remove any remaining adhesive fumes and keep your lashes clean and hygienic. It is important to maintain proper hygiene and cleanliness of the lashes to prevent the buildup of bacteria and dead skin cells, as well as to enhance the longevity of the extensions. Washing your lashes daily is recommended to ensure optimal results and to avoid any potential health problems.


Why use Eyelash Adhesive Holders or Glue Gaskets rather than Jade Stones?

The use of eyelash adhesive holders, also known as glue gaskets, is a preferred option for eyelash extension enthusiasts as compared to jade stones. This is due to the exposure of the adhesive on a jade stone to various environmental factors, leading to the need for frequent replacement of the adhesive. In contrast, the unique concave shape of a glue gasket protects the adhesive from environmental factors, keeping it fresh and usable for an extended period of time, ensuring a smooth and seamless application process.


By utilizing an eyelash adhesive holder, you can save time and money by reducing the need for frequent replacement of the adhesive. 



How often should I change my glue spots when lashing? 

The frequency of changing glue spots during eyelash extension application depends on the room conditions. If the room temperature is warm, the glue will cure faster, and it may be necessary to change the glue spot every 20 to 30 minutes when the glue begins to thicken. On the other hand, if the room temperature is cooler, the glue can last up to an hour. There is no one set answer, as the frequency of changing glue spots ultimately depends on individual experience and professional judgment.

If you notice that your lashes are not adhering as effectively as they were or if balls of adhesive are forming on the extensions, it's time to change your glue spot. Regularly monitoring the performance of your glue and adapting accordingly will ensure a safe and successful eyelash extension application.


The importance of shaking the Lash Glue Well on each use.

Shaking eyelash adhesive thoroughly before each use is an important step in ensuring its effectiveness and longevity. During downtime between clients, the adhesive in the pot remains stationary, causing the ingredients inside to separate over time. If the adhesive is not properly mixed, it may become clear or grey, indicating that it has not been shaken enough. The proper colour of the eyelash adhesive should be black.


Therefore, it is imperative to shake the adhesive well before each use to properly mix the ingredients and maintain its effectiveness. Properly mixed adhesive will provide a strong bond, resulting in a successful and long-lasting eyelash extension application. Neglecting to shake the adhesive can lead to weaker bonds, inconsistent results, and decreased longevity.


ALLERGIC REACTIONS to Eyelash Adhesives

Clients may experience allergic reactions to lash glues due to hormonal changes, changes in medication, and improper care of their lashes after the eyelash extension procedure. Misconceptions, such as avoiding getting the lashes wet in the first 24 to 48 hours, can contribute to these reactions. Clients need to wash their lashes after the procedure to remove any remaining adhesive fumes.


Fumes left on the lids for an extended time can lead to allergic reactions, as well as the buildup of bacteria and dead skin cells if the lashes are not washed regularly. Cleaning the lashes and lids daily will not only enhance the longevity of the extensions, but it will also reduce the risk of developing Blepharitis or Meibomian gland dysfunction.


Blepharitis and Meibomian gland dysfunction occur when the tiny holes in the waterline or tightline become blocked, preventing the natural oils produced by the eye from flowing out and keeping the tears wet, leading to dry eyes. If a client is experiencing these symptoms, it is important to advise them to consult a GP. Proper care of the lashes, including daily cleaning, is crucial for avoiding any potential health problems and ensuring optimal results from eyelash extensions.



How to use eyelash adhesives safely:


Using eyelash extension adhesives safely is crucial for the health and well-being of clients and lash artists. To use adhesives safely, the following guidelines should be followed:

  1. Read the product label and instructions: Before using any adhesive, it is important to read the product label and instructions carefully to ensure that the adhesive is being used correctly and safely.
  2. Perform a patch test: Before using an adhesive on a client, it is important to perform a patch test to ensure that the client is not allergic to the adhesive. This can be done by applying a small amount of the adhesive to the client’s skin and monitoring for any reactions over 24 hours.
  3. Wear gloves: To avoid skin contact with the adhesive, it is important to wear gloves when applying eyelash extensions. This will help to reduce the risk of skin irritation and allergic reactions.
  4. Use proper ventilation: Adhesives can release fumes that can be harmful to inhale. To reduce the risk of inhaling these fumes, it is important to use proper ventilation in the work area. This can include opening windows or using a ventilation system.
  5. Keep adhesives out of reach of children and pets: Adhesives should be stored in a secure, out-of-reach location to prevent accidental ingestion or skin contact by children and pets.

By following these guidelines and using adhesives safely, individuals and lash artists can ensure the health and well-being of their clients and themselves.
