I went in to see Amy for a shellac manicure. We discussed that my job involved working with computers and taking apart hardware, using tools, and other types of nail breaking working. I'm so happy to say that I did a complete system board replacement on a laptop and I don't have a single chip. In fact at 10 days later, my nails are still absolutely perfect. I chose a dark color so of course you can see a bit of regrowth but they still look fabulous.
