Who is Flexie Glue for?
Designed strictly for advanced professional lash artists who work quickly. If you need a fast-drying professional eyelash glue that forgives the natural movement of the lashes, Flexie is your perfect match. (Note: This lash adhesive is not suitable for beginners or intermediate artists).
What is Flexie Glue for?
Flexie is a top-tier eyelash extensions adhesive renowned for its unique, velvety consistency. It dries extremely fast (1 second) and is perfectly formulated for both Classic lashes and Russian Volume lashes. Unlike rigid glues, Flexie stays flexible after curing, reducing the chance of extensions snapping off.
When Should You Use Flexie Glue?
Use this professional lash adhesive when you are struggling with low-humidity conditions. Flexie is formulated to perform perfectly in environments with 40% - 70% humidity and temperatures between 18°C - 22°C.
Why Choose Flexie Glue?
Because rigid bonds break, but flexible bonds last. Flexie gives you the ultimate control over your adhesive pick-up, while its built-in flexibility guarantees exceptional lash retention. It adapts to clients who naturally rub their eyes or sleep face-down, making it a lifesaver for tricky retention cases.
How to get the best eyelash extension retention with Flexie Lash Glue?
If your room conditions are off, your retention will suffer. If your extensions are brushing off or retention is poor, run through this professional checklist:
- Control Your Environment: Always monitor your room with a hygrometer. If your humidity drops below 40% or temp below 18°C, Flexie will dry slower. If the humidity exceeds 70% or the temperature exceeds 22°C, it will dry faster.
- Manage Your Drop: The velvety texture requires a fresh drop every 10-20 minutes. Do not add fresh glue on top of an old drop (it will become gloopy). Pick up the perfect bead and keep in mind that a layer too thin won't hold the extension.
- The Perfect Prep: Cleanse natural lashes thoroughly with Lash Foam Cleanser and Protein Remover Pads. Follow with Cleanser to strip remaining oils, and Primer to hydrate and neutralise the pH level. For an extra bond, use Retention & Speed Booster to open the hair cuticles.
- The Final Seal: Finish with Superbonder Lash Sealant. It cures the glue instantly and enhances Flexie's natural flexibility.
- Application Check: Ensure a minimum 2mm attachment with the natural lash. Check that there are no split or criss-crossed bases.

FAQs
Which glue is the fastest?
Our fastest glues are Power Bond, Royal Bond and Swift Bond and they are drying in 0.5-1 second if used in their recommended temperature and humidity range.
Power Bond works best in 18-22°C (64.4 - 71.6°F) and 50-65% humidity.
Royal Bond works best in 18-22°C (64.4 - 71.6°F) and 30-80% humidity.
Swift Bond works best in 18-22°C (64.4 - 71.6°F) and 40-85% humidity.
Remember, that the higher the humidity in your room, the faster any glue works! Please note that the adhesives listed above are extremely fast and should be used only by HIGHLY EXPERIENCED technicians. Incorrect work with fast-drying adhesives can cause retention problems.
Which glue is best for me?
The best lash glue for you will depend on a few different factors. As a beginner, you’ll be looking more at glues like Lady Bond or Satin Bond which have a more gradual drying time. Check out our glue comparison table for a complete guide to picking your glue.
For the most accurate suggestion, you’ll need to know
Your room temperature
Your room humidity
How long it takes you to place an extension on the natural lash after you’ve dipped it into the glue
So it’s worth investing in a hygrometerto keep an eye on your typical room conditions.
For more information on how to select the perfect lash glue for you, check out our blog A Guide To Picking Your Perfect Match!
Or alternatively, contact our customer care team at info@londonlashpro.com
Which glue is suitable for sensitive eyes?
All our glues contain the same active ingredient, which is cyanoacrylate. The majority of allergic reactions are caused by the fumes of cyanoacrylate. If a client has experienced a reaction, the likelihood is now they will always be allergic. That is why we do not recommend performing a treatment on a client who had previously developed an allergic reaction to the adhesive or is showing any signs of the reaction.
If you perform a treatment on a client with contraindications to the treatment, you may not be covered under your beauty insurance.
Clients who experience just mild discomfort from the glue fumes may benefit from reducing the fumes with Superbonder at the end of the treatment.
Another tip will be to reduce the glue fumes around the client’s face by using the Glamcor Flow to extract the glue fumes and improve the air quality.
My glue is drying too slow
Your room conditions may be affecting the polymerisation process of the adhesive.
We would suggest trying to increase the humidity in the room for faster adhesive polymerisation and adjusting your temperature accordingly. You can also use Booster on the lash strip to increase the speed of polymerisation and improve the retention.
We would highly recommend purchasing a Hygrometer to monitor your room conditions and ensure you are working within the optimal room conditions for your adhesive.
Here are a few tips on how you can increase the humidity in your lash room/salon:
1. Place a damp towel over the radiator
2. Get a humidifier - you can pick up cute little ones on the internet, and for an added little touch of relaxation and luxury for you and your clients, you can add a little drop of essential oil to give out a delicate scent!
3. Add some little droplets of water along the eyepatch using a microfibre brush
4. Apply Primer in sections as you work to keep the lashes moistened
Alternatively, if you have been lashing for a while, you may simply have improved your lashing speed! In this case, your lash glue may now be too slow for you. Why not consider testing out a faster-drying adhesive?

My glue became gloopy, why?
There are a few reasons why your glue could become gloopy, however, it usually comes down to incorrect storage and care of the bottle itself.
Here is a little checklist to prevent it from happening:
Ensure your glue is not expired and that it was stored correctly in a cool, dark place, away from direct sunlight and protected from humidity
Ensure that no residue glue in the nozzle has been pushed back into the glue bottle - this may ruin the rest of the glue
Check if your glue has not been opened for longer than 8 weeks
Ensure you close the glue correctly straight after pouring out the drop of glue as otherwise, the glue can start changing its consistency
Do NOT wipe the nozzle with a wet wipe as it may cause the glue in the bottle to become gloopy
If you require any assistance with your lash adhesive, get in touch with us by emailing info@londonlashpro.com including your order number with a description of the problem.
My fans are closing, why?
The number one reason why your Russian Volume fans will be closing from the point of dipping them in the lash glue, is simply that your lash glue is drying too slowly for you.
We would first recommend reviewing the necessary room conditions for your glue and adjusting accordingly to increase the temperature and humidity. A great solution to prevent fans from closing and control and improve the bonding process is using Booster on the lash strip before you pick off the lashes to create your fans.
Important note: Booster should not be applied to the natural lashes.
We also recommend checking the amount of glue that you are picking up, as using too much adhesive can also cause the fans to close.
How do I clean my glue nozzle?
Use a glue nozzle wipe to wipe off the glue from the nozzle after every use. Keep the bottle in an upright position and squeeze the bottle gently to get glue residue out of the nozzle.
When shaking the glue by hand, make sure to remove the cap first, and cover the nozzle with a glue nozzle wipe. This will prevent the glue from getting stuck in the cap.
When shaking the glue with a glue shaker, ensure to hold the glue shaker in an upright position so the bottle is facing vertically (with the cap at the top) and when finished, remove the cap and wipe the nozzle with a glue nozzle wipe.
Important safety note:
Do not use cotton pads, cotton wool, tissues, or any fibrous materials to clean the nozzle. Cotton fibres can react chemically with cyanoacrylate-based adhesives, which may cause rapid curing, heat build-up, or present a flammability risk. Always use lint-free glue nozzle wipes only.
For more information on the correct storage of your lash glue, read our Glue FAQ blog!
What is the shelf life of the glue?
The shelf life for our glues before opening is 6 months from the date of production. This can be found printed on the bottom of the bottle or the foil pouch the glue arrived in.
After opening a glue bottle, we recommend changing your glue bottle every 4 weeks for the best retention, and maximum every 8 weeks. To keep an eye on the freshness of your glue, simply stick a piece of tape with a written date when you open your glue.
Please note that sample-size (2ml) adhesives should be used within 5 days of opening, which differs from the recommended usage timeframe for our 5ml bottles.
My glue nozzle got blocked, what do I do?
You can purchase a spare nozzle to replace the blocked nozzle. If the nozzle got stuck to the cap, we recommend trying our Glue Rescue Kit.
Our Glue Nozzle Opener is also a great tool to make nozzle changes quick, clean, and easy.
To prevent it from happening in the future, please ensure to clean your glue nozzle after every use, always store your glue correctly, and do not squeeze the bottle to dispense a glue drop.
My glue bottle has a white residue, why?
The white residue on your glue bottle is adhesive that has shock polymerised due to exposure to moisture. This may be caused by not storing your glue correctly or by not fully closing the glue cap.
Please ensure you always store the glue in an airtight container, away from direct sunlight and that the glue cap is always fully attached to the bottle.
My glue appears clear, is it normal?
Every glue should be shaken for at least 1-2 minutes prior to use for the ingredients to mix. If you are using a Glue Shaker this time will be cut down.
Unless you are using Crystal Bond, which is a clear glue, your glue drop should always be black without any traces of transparent liquid. Ensure you shake the glue not only before the first use of the day but also each time you open it to refresh your glue drop.
How should I store my glue correctly?
Before opening:
For optimal shelf life, your adhesive can be stored in the refrigerator while still sealed in the original vacuum pack provided. This helps to preserve its stability prior to first use. Make sure the glue remains inside the vacuum packaging until you are ready to open it.
After opening:
Once opened, your glue should not be stored in the fridge. Instead, keep it at room temperature in an airtight container, away from direct sunlight, heat, or humidity. Always store your glue upright to prevent leakage and to help maintain its consistency.
Proper storage is key to maintaining the performance and longevity of your adhesive.
How do I remove lash adhesive safely?
Lash extensions should be removed by a qualified professional only using products designed specifically for professional use. Never attempt to force, pull, or peel extensions off, as this can cause damage to the natural lashes and skin.
For safe and effective removal, we recommend using a dedicated professional lash adhesive remover such as our Cream Remover or Gel Remover. This is designed to gently dissolve adhesive bonds, allowing you to remove extensions in a controlled and precise way without unnecessary tension on the natural lashes.
Always follow correct removal techniques, work in small sections, and ensure your client’s eyes are properly protected throughout the process.
