Lash Glue vs. Summer

Summer is almost here, and with it comes plenty of sunshine, beach trips, and fun in the sun. However, for lash technicians, the hot weather can be a real challenge when it comes to lash glue. Even the best eyelash glue can become temperamental in hot weather. However, there are ways to overcome this issue.

One of the key factors that can affect how well your glue works is the environment in which you work. Humidity and temperature are particularly important. Temperature is the most noticeable factor, as you can usually perceive changes in temperature easily. On the other hand, changes in humidity can be more difficult to detect. If you notice a rise in temperature, you can try to cool down the room to lower the humidity. However, it's important to strike a balance, as opening a window to let in some fresh air may increase the humidity and speed up the drying time of your adhesive. Conversely, using an air conditioner can help to reduce the moisture in the air, but may also slow down the drying process of your glue.


If you are working in an environment with low humidity, your glue may slow down and become difficult to work with. This will cause the adhesive to take longer to dry, which means you'll have to hold the eyelash extension in place for a longer time. If you are doing volume fans, this may cause them to close or lean to one side, which is not ideal.

One solution to this problem is to use a humidifier. You can even use scented humidifiers to create a more luxurious and comfortable experience for your clients.

To keep the lashes moistened, apply Primer in sections as you work.

Using our Megabonder 2 in 1 as pretreatment (glue booster) on the lashes will give the lash glue a better grip. Megabonder has an alkaline pH, which causes the hair cuticle to open up slightly, providing a larger surface area for the glue to latch onto. A helpful tip is to use a dab of Megabonder 2 in 1 on the lash strip. By doing this, you can prevent the fans from closing and speed up the glue's drying time.

To keep track of the temperature and humidity around your workspace, add a hygrometer to your collection. This will help you ensure that you are working in the correct conditions. Lastly, remember to store your glue in the recommended place to extend its shelf life and save money in the long run.


When the humidity is high, your lash glue can dry too quickly, leading to poor retention of the extensions. You don't want to finish a set of perfect lashes only to have them fall off within days. While a dehumidifier can help, they can be bulky and noisy. If that's not for you, consider switching to a glue that dries more gradually. Our Lash Adhesive Collection offers a variety of options, and our Glue Chart can help you find the perfect one for your needs.



Top tips:

- It's important to regularly change the glue dot while working in varying temperature and humidity conditions. Observe how your glue behaves on the dot as it can affect its performance, not only when applied to the individual lashes. If your lash glue starts to become stringy, it's time to get a new drop.

- To ensure that the bond remains flexible and not brittle, use Megabonder at the end of the treatment. It instantly cures the glue, allowing your clients to continue their summer activities without worrying about retention.

- Once your client leaves, it's up to them to maintain their lashes. Encourage them to return for an infill after about two to three weeks to keep their lashes looking fresh for the rest of the season.

In conclusion, coping with lash glue in hot summer weather can be a challenge, but it's not impossible. By working quickly and efficiently, using a fan or air conditioning, choosing the right glue, and being prepared to make adjustments as needed, you can ensure that their clients look and feel their best, no matter the temperature outside.
