I bought a groupon for shellac. The lady was very nice, and her work space was very clean and sanitary. I only gave 3 stars because she did not do much to my nails before applying the shellac. As a result, my cuticles are very dry. Also in between layers, I noticed that almost every nail has dust or black hairs, which isn't fun.
The price was great, but I wouldn't pay full price for shellac here.
