How to Achieve the Best Retention with MARY LASH m2 Glue?
The ideal temperature for m2 glue is 64.4–82.4°F with a humidity of 30-80%.
Remember that if:
- The temperature is below 64.4°F, the glue may dry slowly.
- The temperature is above 82.4°F, the glue may dry faster.
- The humidity is below 30%, the glue may dry more slowly.
- The humidity is above 80%, the glue may dry faster.
Working in the glue's ideal conditions will ensure the correct drying time, leading to excellent retention. To monitor the conditions in your workspace, we recommend using a hygrometer.
The simplest way to adjust the temperature in your lash room is to use an air conditioner, fan, or heater/radiator. To increase or decrease humidity, use a humidifier or dehumidifier.
Remember that improper handling of the glue can lead to poor retention. If your room has high humidity and temperature, your glue will dry much faster. However, since the speed of your work does not increase accordingly, you may experience poor retention, causing lash fallout 2-3 days after the procedure.
Your retention may also suffer if your glue is not fresh or if you store or use it incorrectly. The shelf life of m2 glue before opening is 6 months from the date of manufacture. After opening, we recommend changing the glue bottle every four weeks for the best retention. The maximum time after opening is 2 months, but if the glue is opened several times a week, or if the technician has appointments every day, it is better to change the glue every 4 weeks.
Remember to store the glue upright, in a dry place, away from direct sunlight, ideally in an airtight container. To track the glue's freshness, simply attach a piece of tape to the glue bottle with the date of opening written on it. For shaking the glue, it is better to use a glue shaker to ensure a uniform consistency for better retention. Remember to wipe the nozzle after each use to prevent clogging of the nozzle and cap.
If you notice that your retention is not perfect, follow this checklist:
- Check the humidity and/or temperature levels in the room to ensure they are at the recommended levels.
- Ensure proper cleaning of natural lashes – we recommend using a lash foam to clean the area around the eyes from makeup. After thorough cleaning and applying patches, prepare the natural lashes with a degreaser.
- If the glue is working slowly, apply MARY LASH Primer to the lash strip; if the speed is insufficient, use a booster to make the glue work faster.
- Make sure you are always working with a fresh drop of glue (we recommend changing the glue drop every 10-30 minutes – or even more frequently during hot months or in high humidity).
- Ensure you are using an adequate amount of glue – too small a drop, which is not visible or too thin a layer of glue, may not be sufficient to hold the lashes on the natural lashes for the next few weeks.
- Check your bonding technique (at least 2 mm bonding with the natural lash, no split or crossed bases).
- The glue drop used should not be too large (the larger the surface area, the more glue is in contact with the air) or too small (the glue drop will dry too quickly).
- Do not add fresh glue to the previous glue drop (contact between the "old" and "new" drops will make the glue become sticky very quickly).
If none of the above points work, switch to glue with a slightly slower drying time (e.g., m1) or consider enrolling in a course at MARY ACADEMY.

This glue is a total game-changer! It’s super liquid and flexible, making it so easy to separate lashes. And when I pair it with a booster, there’s no stickiness at all! It works perfectly in any conditions. Thank you for creating such an amazing product

I absolutely love this glue! I had a client with allergies, and with this adhesive, everything went perfectly—no reactions at all. My client was so happy, and so was I! Definitely ordering this again.

Frequently Asked Questions
Below you will find some common questions asked by our customers about our products.
REASONS FOR POOR LASH RETENTION:
Glue speed- the glue worked too fast or the glue itself was too fast. Therefore, you just couldn't keep up with the glue, but the performance of your glue might have been accelerated by improperly used products or mistakes in the sequence of work.
Solution:Use a slower glue (for example, M1).
1. DO NOT use primer/booster on natural lashes and on the lash strip. If you have already used it, switch to the other eye or use lashes from the other side of the strip where there is no product.
3. Clean the lashes with products that have a neutral pH (MARY LASH degreaser, foam, saline solution).
4. In your work, first isolate the natural lash with straight tweezers, and only then dip the artificial lash in the glue.
5. It is important to place the lash correctly on the first attempt, you should not place it on the natural lash multiple times.
6. Drop a new droplet of glue - preferably in a glue ring - as the glue thickens more slowly in it.
GENERAL RULES THAT ALWAYS APPLY
1. Change Glue Regularly:
- Replace glue every 3-4 weeks, even if some remains. If you open the bottle only 1-2 times a week, you can stretch it to 2 months.
2. Monitor Room Humidity and Temperature:
- Always keep an eye on the humidity and temperature levels in your workspace.
3. Ventilate the Room:
- Ensure to ventilate the room before each client session.
4. Properly Clean Natural Lashes:
- Use a lash foam cleanser to clean natural lashes and the surrounding eye area from makeup.
5. Apply Neutral pH Degreaser:
- After thorough cleaning and applying patches, use a neutral pH degreaser on natural lashes.
6. Refresh Glue Drops Regularly:
- Change the glue drop at the first sign that something feels off (every 10-30 minutes).
7. Mix Glue Thoroughly:
- Mix the glue well for 30 seconds before dispensing a fresh drop, or use a glue shaker.
8. Avoid Mixing Old and New Glue:
- Do not add fresh glue to an old drop. Contact between the "old" and "new" drops will make the glue become sticky quickly. Discard the old drop before adding a new one.
9. Do Not Wipe the Lash with Glue on the Patch:
- The amount of glue should be adjusted by the speed at which you pull the lash from the glue drop.
10. Store Glue Properly:
- Keep the glue in a thermal bag and in a cool, dark place.
11. Keep the Glue Nozzle Clean:
- Always keep the glue bottle nozzle clean.
12. Wipe the Glue Nozzle Each Time:
- Clean the nozzle every time you use it.
13. Replace Nozzle and Cap Together:
- Change the nozzle along with the cap.
14. Hold the Tube Vertically:
- Keep the tube vertical when dispensing a drop.
15. Close the Glue Tightly:
- Ensure the glue is tightly sealed for proper storage.
GLUE WORKS SLOWLY:REMEMBER - it is much easier to speed up the glue than to slow it down! So, it is not as bad as it might seem.
1. To speed it up, apply primer to the lash strip. If that is not enough, apply a booster to the lash strip. If it still doesn’t help, apply the booster to the natural lashes in the area without artificial lashes. Refresh the products every 30 minutes.
2. Check your work sequence - in such a case, it is important to first dip the artificial lash in the glue, and only then isolate the natural lash with straight tweezers and place the artificial lash on it.
3. Too much glue - this is a very rare case. Remember, the amount of glue depends on the thickness of the natural lash.
4. Very fresh glue - glue just after opening always works slower because it is very fresh and contains a lot of stabilizers.
5. Drop a new droplet of glue - a micro-droplet on tape works faster than in a glue ring.
6. If possible, increase the temperature and/or humidity in the room, and the glue will work faster.
7. If available, use a faster glue (for example, M4).
CHANGES IN GLUE BEHAVIOR DURING USE
The fresher the bottle, the slower the glue works, and conversely, the longer it has been opened, the faster it works. The same applies to the texture: the fresher the glue, the more liquid it is, and when the glue has been open for a long time, it becomes thicker, which significantly affects its performance.
WHY IS THIS?
This is due to the amount of stabilizers in the glue. With each opening, the amount of stabilizers decreases, causing the glue to change its behavior even under the same conditions.
Solution:
- Consider the texture of the glue. If you prefer working with liquid glue, use smaller volumes and change the bottle when the texture starts to change.
- Conversely, if you cannot work with liquid glue, open the bottle, use it until the end, and opt for a larger volume.
- It is essential to adapt to the glue's behavior based on these changes. Use the tips above to adjust accordingly.
Reasons That Could Affect Glue Performance:
1. Changes in Temperature/Humidity:
- Higher temperature and humidity levels make the glue work faster, and lower levels slow it down. Refer to previous tips on how to handle these changes.
2. Oxygen Levels in the Air:
- If there is insufficient oxygen, the glue performs poorly, and the technician may not understand why. Ensure to ventilate the room properly.
3. Additional Scents:
- Perfumes (yours or the client's), air fresheners, the smell of lamination solutions, hair dye, and other strong odors can negatively affect glue performance.
4. Technician's Mood:
- Sometimes, everything seems to go wrong, and the glue doesn’t work well, making you want to give up. Remember, it's just one of those days. If possible, take a day off, treat yourself to something nice, or do something just for you, not for your family, clients, or friends, but for yourself. The technician's mood is very important. Keep a positive attitude and don't forget about self-care.
