GlueCast: Lash Humidity Guide

Lash tech? Check today's humidity and know which adhesive to use, estimated cure time, and when to refresh your glue drop. Based on your glues and local weather.

Stop guessing how your lash adhesive will perform today. GlueCast checks local humidity and temperature, then tells you which glue from your collection works in current conditions, with an estimated cure time and glue drop refresh interval.

Every lash tech knows the frustration: retention was perfect last week, but today extensions are popping off. The reason? The humidity changed, and your adhesive is curing too fast — or too slow.

HOW IT WORKS

1. Add your adhesives: select from 19 pre-loaded brands or enter custom specs (cure time, humidity range, temperature range).
2. GlueCast fetches current weather conditions at your location.
3. You get today's condition status, which adhesive fits, adjusted cure time, technique tips, and glue drop refresh timing. It takes 30 seconds to set up. No account required.

TODAY'S CONDITIONS See your local humidity and temperature displayed as a clear GREEN / YELLOW / RED status. Know instantly whether conditions are ideal, too dry, or too humid for lashing — before your first client sits down.

TECHNIQUE TIPS Get condition-based guidance: how to adjust your dip depth, which viscosity works in current conditions, and how often to refresh your glue drop on the jade stone.

ADHESIVE MATCH Save your adhesive collection with each product's specs. GlueCast matches current conditions to your glues and tells you which one to reach for today.
