3. Ask what kind of lashes do they use?
The answer would be synthetic lashes, mink or silk.
4. Is it a one to one application?
I am finding that salons are using "flairs" or "tabs". This product can be bought at CVS or Walgreens. There are five lashes joined together. Looks like a fan of lashes. These are being applied with semi-permanent glue. They will pull out your lashes because they are not meant to be applied with the semi-permanent glue. "Flairs" should only be worn for a short period of time.
