Hygrometer

The hygrometer is the essential accessory when you practice the application of eyelash extensions. So you can always have an eye on the humidity level or the ambient temperature in your room. You should know that these two elements are essential to ensure the proper use of lash glue.
Indeed, if you have a room that is too hot and/or humid or vice versa, this will have a significant impact on the polymerization of the lash glue.
Do not hesitate to use a humidifier if you lack humidity in your work room.
