1. Bare-Naked Nails
Before starting, ensure that your nails are as clean as possible. Use this Sally Hansen Acetone-Free Nail Polish Remover ($4.63) on cotton pads to gently remove any old polish, dirt build-up up and and oil on the nail bed. You only need a small amount, and while professional manicurists often use alcohol to remove polish, this non-acetone version is much healthier for your nails. Be sure to sweep down the sides of your nails, and underneath, to capture any dirt or residue.
