Hot for Humidity


Feeling stuck searching for the “best” lash extension adhesive on the market to maximize your lash retention? Sorry to break it to ya, babe, but there’s no such thing as the best eyelash glue in the world. Every artist is compatible with a different eyelash adhesive based on the humidity in the space you’re lashing in. There’s hundreds of adhesives to choose from, and your soulmate formula isn’t always easy to find. Breaking down what adhesive works best for you, your clients, and your work space will help you find your match made in lash heaven.


All adhesives contain cyanoacrylate, which cures in the presence of moisture - aka the presence of water is what causes the glue to solidify its bond between the natural lash and the extension. The higher the humidity, the faster the adhesive will cure. The humidity, or moisture in the air, in a studio in Florida is going to vary from the humidity in a studio in Arizona. It’s the mark of an educated lash artist to understand the humidity in the room + which products will work best in your environment.


A hygrometer is a must have in a lash artist’s kit. This essential device measures the temperature and humidity in your room. In order to accurately measure your humidity, let the device read the room for an hour and take note of the numbers. For best results, do this three times a day for two days. Afterwards, add the six percentages together, then divide by 2. This is how you can find average relative humidity (ARH). If your ARH is under 30 percent, try adding a humidifier to your room. If your ARH is over 80 percent, a dehumidifier will help you bring the humidity down. A 45 to 55 percent humidity reading is the best range for applying lash extensions. Once you know what you’re working with, you can start looking for the right eyelash glue for your humidity.


Yes! You absolutely need to store your adhesive properly when you’re not using it to protect it from humidity and keep it from being compromised. If moisture enters the eyelash glue, it can start to cure inside the bottle and it’ll no longer be usable. Treat your beloved glue to a safe, dry place to cuddle up for the night and get a Love Shack - our vacuum-sealed storage that will extend the shelf life of your opened adhesive by keeping it safe in an airtight container with silica beads.
