Safety & setup
Take this chapter at your pace. Use the summary, media, and completion controls when you are ready to move forward.
Humidity and temperature change cure speed. Log room RH when you open a bottle.
If the extension slides, strip and re-isolate — never force a second dip.
The short version
Adhesive speed changes with temperature and humidity. Record your room conditions, isolate first, and use a clean micro-drop so placement stays controlled.
Final submission required
Upload a before photo, a clear lash map, and three finished-set angles. Your educator reviews isolation, direction, and styling before certification.
