Thank you very very much.You should expect
No buffing of the natural nail surface
Your nails should be cleaned thoroughly with SCrubFresh before application
A good competent application of Shellac Base Coat
Two coats of Shellac colour
A coat of Shellac Top Coat.
You should see a UV Lamp with CND embossed on the top of the lamp.
Every bottle should be of the same type and shape, and every bottle should say CND Shellac on the lable.
You should have your nails wiped with D Sperse at the end of the service
If you don't see ALL of those things, BEFORE you have your Shellac applied, then I would say, "thanks but no thanks".
