Hygrometer – Monitor Your Room’s Humidity & Temperature
Why Humidity Control Matters
Lash glue is extremely sensitive to the environment. If humidity rises above 55% RH, adhesive cures too quickly, which can cause weak bonds and closed fans. If it drops far below 55%, curing slows down and retention suffers.
Keeping your lash room at 55% RH gives your glue the perfect conditions to work exactly as designed, resulting in smooth application, strong bonds, and long-lasting sets.
How This Kit Helps You Stay at 55%
Our Lash Room Humidity Monitor Kit includes two smart sensors:
-
One for your lash station – the critical area where maintaining 55% RH ensures consistent adhesive performance.
-
One for outdoors – so you know whether opening a window will help balance your lash room or push it off target.
Even a short deviation away from 55% RH can affect curing speed and retention — which is why continuous monitoring is essential.

Why This Matters for Lash Retention
Stable humidity at 55% RH is the single most important factor in getting the best results from lash glue. Combined with our cosmetic grade adhesives — Daisy (methoxy-based) or our ethyl-2 cyanoacrylate range — maintaining 55% RH ensures predictable curing, strong bonds, and longer-lasting lash extensions.
