To make sure I was evaluating every nail polish fairly (and to test every polish’s true limits), I kept these variables consistent over my month-long experiment:
• Apply polish the same exact way. For each test, I painted three layers on each nail.
• Wear each polish for 7 days. At the end of the week, I would assess any chipping.
• Test two brands at a time, alternating the colors on both hands. This was to offset more potential chipping on my dominant hand (my right hand).
• Use light or semi-light polish colors. More on this below.
• Avoid base coats, top coats, and gel formulas. I opted out of base coats and top coats in order to keep the focus on the polish itself. I also avoided gel polishes because their long-wearing formulation gives them an unfair advantage over ‘regular’ polishes.
