Does nail polish fade why or why not?

Yes, nail polish can fade over time due to exposure to sunlight, chemicals, and everyday wear and tear. UV rays can break down the pigments in the polish, leading to discoloration, while harsh soaps and cleaning agents can wear it away. Additionally, the natural oils from your skin and environmental factors can contribute to fading. To prolong the life of nail polish, using a top coat and avoiding prolonged sun exposure can help.
