Again, this is why you want a trained professional who knows how to safely use the glue and knows how to properly remove the glue. Untrained technicians are not aware of the proper hygiene and techniques when using synthetic eyelash glue. Inexperienced technicians may not know how to properly use the fast drying glue and the result could be a very unflattering look. The eyelashes could become clumpy. Only a trained person should apply the eyelashes using this special glue.
