I am clueless about nails! Never normally bother with varnish, as can't wear it at work, so it isn't worth it, but I'm about to have three weeks off work, will be away on holiday for 2 of them so would like to have pretty nails for once. I want something that won't need much attention and can be easily taken off before I go back to work. Do I do them myself or go and have them done? What do I actually need? Gel? Shellac? Somehing else? Help!
