When it comes to achieving perfect eyelash extensions, mastering your technique is only part of the equation. The environment in which you work plays a huge role in the results. One of the most overlooked factors affecting lash retention is humidity. Understanding the best humidity for lash glue can significantly improve your client’s lash longevity and overall experience. In this guide, we’ll break down everything you need to know, including tips for optimising your workspace and using Posh Deluxe products to get the best results.
Why Humidity Matters for Lash Glue
Eyelash adhesive is highly sensitive to both humidity and temperature, and even small variations can impact its performance. The curing process of lash glue — the chemical reaction that allows the adhesive to bond lashes together — depends on the moisture in the air.
-
Low humidity: In dry environments (below 40% humidity), lash glue cures more slowly. This can result in lashes sliding, sticking together, or weak bonding that reduces retention.
-
High humidity: In overly moist environments (above 60% humidity), lash glue cures too quickly. While this may sound ideal, it can cause retention issues as the glue cures way too fast before you get to the natural lashes. Lash wrapping would also be impossible in this scenario.
For professional lash artists, balancing humidity ensures that the adhesive performs consistently, providing optimal bonding strength and long-lasting lashes.
Optimal Humidity Range for Lash Extensions
For most professional lash adhesives, including Posh Deluxe Elite Bond Adhesive and Bond Babe Adhesive, the best humidity for lash glue is typically between 40% and 60%.
-
Below 40% humidity: The adhesive may dry too slowly, leading to weak lash retention and more time spent correcting lashes.
-
Above 60% humidity: The adhesive may cure too quickly, making precise application challenging and increasing the risk of lashes sticking together or forming clumps.
Maintaining a stable humidity within this range ensures that your lash extensions adhere perfectly while giving you enough working time to create clean, natural-looking sets.
How Temperature Affects Lash Glue
While humidity is key, temperature also plays an important role in lash glue performance. The ideal workspace temperature is usually between 20°C and 24°C (68°F – 75°F).
-
Too cold: Glue may become thick and slow to cure.
-
Too hot: Glue can dry too quickly, reducing working time and making precision applications harder.
By controlling both temperature and humidity, you can create the perfect environment for Posh Deluxe lash adhesives to perform at their best.
Tips for Controlling Humidity in Your Lash Studio
Even small fluctuations in humidity can affect lash glue performance. Here are some practical ways to maintain the optimal environment:
-
Use a hygrometer: Regularly monitor your studio’s humidity to ensure it stays between 40% and 60%.
-
Invest in a humidifier or dehumidifier: Depending on your climate, these devices help stabilise humidity levels for consistent results.
-
Avoid drafts: Keep clients away from vents, fans, and open windows, which can disrupt glue curing.
-
Store adhesives correctly: Keep lash adhesives in airtight containers or the fridge to maintain their consistency and effectiveness.
-
Adjust working techniques: In higher humidity, work slightly faster to prevent premature curing; in lower humidity, allow a few extra seconds for the adhesive to set properly.
By implementing these steps, you’ll create an ideal environment for your Posh Deluxe adhesives, ensuring each application is flawless.

Extra Tips for Longevity
In addition to maintaining the right humidity and choosing quality adhesives, consider these extra tips for maximising lash retention:
-
Avoid water and steam for the first 24 hours after application to allow full curing.
-
Educate clients on aftercare, including gentle cleansing and avoiding oil-based products near the lash line.
-
Rotate adhesive types if working in different climates; some adhesives are formulated for higher or lower humidity environments.
