Humidity and Temperature: Key Factors in Lash Extension Application
Humidity and temperature are crucial elements that significantly impact the success of lash extension applications. As a professional lash artist, understanding and controlling these factors can make the difference between a flawless set and a disappointing result.
Why Humidity and Temperature Matter
These environmental conditions directly affect two critical aspects of lash application:
The drying time of the adhesive
Viscosity of the lash glue
By managing your lash room's environment, you can optimize these factors for the best retention and highest quality application.
The Science Behind Lash Adhesives
Lash glue's principal active ingredient, cyanoacrylate, cures through a unique process:
It reacts with moisture in the air
This triggers a polymerization process
The result is a solid bond between the natural lash and the extension
This chemical reaction is why controlling humidity is crucial for successful lash applications.
Ideal Conditions for Lash Extensions
For optimal results, aim to maintain these conditions in your lash room:
Humidity: 40% - 60%
Temperature: 68°F (20°C) - 72°F (22°C)
These ranges provide the best environment for the lash adhesive and client comfort.
Effects of Low Humidity
When humidity drops below the ideal range:
Adhesive dries slower than normal
Application time increases
The curing process is prolonged
Retention may be poor due to inadequate bonding
Increased number of ‘stickies’
Effects of High Humidity
Excessive humidity can lead to:
"Shock polymerization" - adhesive cures too quickly
Weak, stiff bonds
Premature shedding of extensions
Tips for Managing Humidity and Temperature
To maintain optimal conditions in your lash room:
Use a hygrometer to monitor humidity levels
Invest in a humidifier for low-humidity environments
Use a dehumidifier in high-humidity conditions
Choose the right adhesive for your environmental conditions
Adjust your technique based on humidity levels
Paying close attention to humidity and temperature ensures consistent, high-quality lash extensions that will delight your clients and set your work apart. The best way to know the temperature and humidity at your working station is to buy a hygrometer. We also recommend keeping a notebook nearby and using it as a diary and writing the daily temperature, humidity, and weather daily. Environmental changes such as rain, snow, and heat waves can significantly affect the retention. Some glues, like the Doge’s Palace & The Forbidden City, work well with high humidity and when it rains, and others, like Windsor, are better for those hot, sunny, dry summer days.
