When working with eyelash extensions, glue plays a crucial role in the durability and efficiency of the work. But what should you do when the glue doesn't stick? There are several possible causes for this, and it's essential to identify them to effectively address them. Here are some avenues to explore and solutions to implement to ensure your extensions stay in place perfectly.
1. The cyanoacrylate has weakened or the glue is defective
Cyanoacrylate, the main ingredient in eyelash extension adhesives, can weaken over time, especially if the adhesive has been open for a while or is improperly stored. A faulty or expired adhesive may not provide the necessary adhesion, which can lead to eyelashes falling out quickly.
What to do?
- Check the expiration date of the glue.
- Make sure the glue has been stored properly (at room temperature, away from moisture and heat).
- If the glue has been open for a while, it may be best to replace it.
Tip: To test if the glue is still effective, apply a small drop to a support and try gluing extensions onto a clean practice sponge. If it doesn't stick, it's probably time to upgrade. If the product is new, contact your after-sales service.
2. The client's eyelashes are low porosity
Some lashes, especially those that have undergone chemical treatments or are naturally low-porosity, can be difficult to adhere to. In this case, the problem is not with the glue, but with its inability to properly adhere to the surface of the lash.
What to do?
- Apply a high pH pre-treatment, such as a primer or booster , which will open the lash scales and allow better adhesion of the glue.
- You can also try another type of pre-treatment, depending on the client's specific needs.
3. The humidity level is too low
Cyanoacrylate is a compound that reacts with moisture to polymerize (harden and bond). If the humidity is too low, the glue will not cure properly, resulting in poor adhesion.
What to do?
- Check the humidity level in your workroom. Ideally, it should be between 45% and 70%.
- If the humidity level is too low, you can use a humidifier to regulate the environment.
- Avoid working in rooms that are too dry, such as those with air conditioning.
What if the glue still doesn't stick?
If, after checking all these points, the glue still doesn't stick, it's time to move on to the next step. If the glue doesn't stick to the test sponge, the problem may be with the glue itself.
What to do?
- Contact the glue brand's after-sales service . It's possible there is a manufacturing defect or the glue has been improperly stored.
- If the glue seems to be working normally but isn't sticking to your client's lashes, try a different pre-treatment or adjust the humidity conditions in your workspace.
In short, if your glue isn't sticking, don't panic! By following these steps and checking the various factors that can influence adhesion, you'll be able to quickly resolve the problem. For optimal results, always make sure you work in ideal conditions and choose quality products. And if you ever have any doubts, our after-sales service is there to guide you.
The key is to always test and adjust in order to offer your clients quality service with extensions that last a long time!
