HofG's Thermo-hygrometer is a battery operated device. It has a sensor to monitor the temperature and humidity levels in the room. Every adhesive has different optimum temperature and humidity level. You should always check the environment conditions before applying eyelash extensions.
Here at House of Glam, we do not start work until the temperature and humidity is documented. What about you?
Best paired with: Rock Adhesive or Invisabond Adhesive
