Ensure that you have the proper humidity and temperature in your room. Most eyelash extension adhesives work best at about 24 C and 40-50% humidity. Check with each manufacturer as this varies greatly.
Winter: Add humidity with a humidifier in your room, or place a mister near your clients face
Summer: Use a dehumidifier in your room as needed. Air conditioners will also take out some humidity.
Watch out for drafty rooms where you cannot control the humidity or temperature
Battery Operation: Require 1 x AAA battery (included)
