Lash eXtend article about Bonding agents

The lash industry is ever growing and evolving. The same also applies to our knowledge about products and achieving better results for our clients. Air humidity levels and how it affects the extension bonds is an aspect that is often misunderstood. Stylists often wonder how to store their glue, or bonding agents, properly and what to tell their clients about aftercare procedures.

Lash eXtreme Bond lash extensions glue

Air humidity and humidity itself. Is it good, bad or a necessity? Or maybe a bit of all three?

In regulated amounts, humidity can play an essential role in the application of eyelash extensions, making sure that the bonding agent performs well. Too much humidity can cause things to go awry!

Humidity and the workplace

This is what it is all about: Cyanoacrylate hardens/sets when moisture is introduced. Too much humidity may cause this glue to become lumpy or set quickly, while controlled humidity levels in the treatment area helps to accelerate the bonding to the natural lash.

Humidifiers or (dehumidifiers in extreme climates) are important tools to create the most ideal working environment. Your treatment area must have a relative humidity level of 45 to 55 percent for the Lash eXtend bonding agents to work well. Higher values can introduce application issues, for example, the Lash eXtend Bonder sets after 2 seconds in normal circumstances. A higher humidity level reduces this time to one second or less. This will most likely not be enough time to correctly apply the eyelash extension. Conversely, a working environment that is too dry may cause the lashes to stick together. Keeping the humidity levels in check makes the bonding agent work the way you want it to. You bought the glue with certain specifications in mind, after all, you want what you paid for, right?

Moisture on new lash extensions

For years we believed we had to avoid any kind of moisture for 48 hours after the extensions were placed. Now we know that glue needs moisture to set well. They wont do as well without it. Humidity level management is key.

In earlier days, there were no such things like Lash Misters or sprays to force the setting process in a controlled manner. This did not mean however, that moisture did not harden the glue. In those times ladies avoided the sauna and sweating for 48 hours, because this was too much moisture at once for the glue and the newly placed extensions. Showering, swimming, or working out caused a kind of shock to the bond itself. The shock i.e. sudden hardening of the glue, happened when too much moisture was introduced to the glue that was still wet. A side effect called “blooming” can also occur. A whitish gray substance will appear on the lashes in such cases. In the salons of the old days customers were told to wait for 48 hours. Back then this was the common method to slowly harden the glue and let it interact with the moisture present in the air, in a controlled manner. In this way, extensions were not prematurely exposed to too much moisture, and they could harden slowly, layer by layer, forming a very strong bond.

Disadvantages of not showering, swimming or working out for 48 hours are:

Use moisture to your advantage

Now we know that moisture is necessary to correctly harden the glue in a controlled manner and that too much moisture in the beginning proves harmful for the bond. Now we have the answer to the question on how to influence the setting process while not weakening the bond at the same time. This makes keeping the lashes dry for 48 hours a thing of the past.

Lash misters are now available as a tool to complete the application process. These misters are filled with water droplets that will be spread like a fine mist over the newly placed extensions. Its goal is not to moisturize or suddenly harden the lash bond, but to spread a small amount of moisture in and around your working space, allowing the bond to absorb just the moisture that it needs. The bond will absorb the moisture layer by layer, like a sponge. Because the glue hardens layer by layer, we can easily dry the outer center layer of the bond within 30 seconds by using the mister. The goal is to deliver as much moisture within 30 seconds as would normally have been necessary in 48 hours in days past.

What happens when customers stay put until the glue is set:

Moisture and the glue

There are two factors that contribute to the breakdown of the bonding agent: heat and moisture. Lash glue or bonding agent, prefers a cool, preferably dark storage location. Many stylists were recommended to keep it in the refridgerator, but this proves to be risky as it can harm the integrity of the bottle, and the reason for that is this. New glue works like a sponge, as it absorbs moisture that is present in its surroundings so that it can set. Every time a bottle is opened, theres a chance that moisture can be absorbed. If this bottle is stored in a refridgerator and taken out again, condensation can occur, meaning that there will be liquid on the outside as well as the inside of the bottle. The glue can then spoil even before the expiration date is reached.

Lash glue can be stored in the freezer or refridgerator as long as the bottle is UNOPENED. Once opened, only room temperatures can prevent condensation from happening. All Lash eXtreme Bonds can be stored in the freezer up to 12 months before use in the event that theyre not used immediately. When it is ready for use, let the bottle thaw for 24 hours at room temperature before opening.

To keep your Lash glue fresh right up to the last drop you have to:
