When working with eyelash extensions, glue plays a crucial role in the durability and efficiency of the work. But what to do when the glue doesn't stick? There are several causes that can be responsible for this situation, and it is essential to identify them in order to effectively remedy it. Here are some avenues to explore and solutions to implement to ensure that your extensions hold perfectly.
1. The cyanoacrylate has weakened or the glue is defective
Cyanoacrylate, which is the main ingredient in eyelash extension glue formulations, can weaken over time, especially if the glue has been open for a while or stored improperly. A faulty or expired glue may not provide the necessary adhesion, which can lead to lashes 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 humidity and heat).
- If the glue has been open for a while, it may be best to replace it.
Trick : To test if the glue is still effective, apply a small drop to a support and try to stick extensions on a clean practice sponge. If it does not stick, it is probably time to change the product. If the product is new, contact your customer service.
2. The client's eyelashes are low porosity
Some lashes, especially those that have been chemically treated or are naturally low-porosity, can be difficult to adhere to. In this case, the problem is not with the glue, but with the inability of the glue to properly adhere to the surface of the lash.
What to do?
- Apply a high pH pretreatment, such as a primer Or booster, which will open the eyelash 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 create the bond). If the humidity level is too low, the glue will not be able to 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 to do if the glue still doesn't stick?
If, after checking all these tracks, the glue still does not stick, it is time to move on to the next step. If the glue does not stick to the test sponge, it is possible that the problem comes from the glue itself.
What to do?
- Contact the after sales service (SAV) of the glue brand. It is possible that there is a manufacturing defect or that the glue has been poorly stored.
- If the glue seems to be working normally but is not sticking to your client's lashes, try a other pretreatment or adjust the humidity conditions in your workspace.
In short, if your glue doesn't stick, don't panic! By following these steps and checking the different factors that can influence adhesion, you will be able to quickly solve the problem. For an optimal result, always make sure to work in ideal conditions and choose quality products. And if you ever have any doubts, the after-sales service is there to guide you.
The key is to always test and adjust in order to offer your clients a quality service with extensions that last a long time!
