What are people mostly having done to their nails now? I have been having nail envy recently and went into a nail bar this pm to treat myself. But I was so overwhelmed I didn't know what I wanted and I left. Do people have shellac or gel polishes now? What is the difference? What happens when one falls off? Do people go and get them removed and then new ones put back on again? Does anyone just have a colour polish done any more?
