What is the correct technique for applying nail polish?

The technique involving three strokes—one down the center of the nail and one on each side—is recognized as the most effective method for applying nail polish. This approach ensures even coverage and minimizes the potential for streaks, allowing for a smoother finish. Starting with the middle stroke establishes a solid foundation for even distribution of the polish, while the two additional strokes on either side help to fill in the edges. This technique also helps in avoiding over-application, which can lead to smudging or pooling of polish along the nail edges.

Other application methods may not provide the same level of control or uniform coverage. For instance, applying in a single stroke may leave the edges of the nail bare, while circular motions can create uneven application and can lead to an unsatisfactory finish. Diagonal strokes might not effectively cover the entire surface of the nail either, making them less ideal compared to the three-stroke method. Overall, the three-stroke technique ensures a balanced and aesthetically pleasing result.
