Using a straight filing technique is the recommended approach for acrylic nails as it helps maintain the shape and structure of the nails. Straight filing allows for precision in shaping the tips and sides of the acrylic nails, ensuring a clean and uniform appearance. This technique is essential for achieving a polished look and prevents the risk of weakening the nails, which can occur with more aggressive or improper filing methods.

In contrast, techniques like circular or diagonal filing may not provide the same level of control or consistency when shaping acrylic nails. Circular filing can lead to an uneven texture and may compromise the integrity of the nail. Diagonal filing may introduce an unnecessary stylistic element that detracts from the uniform shape that is typically desired. Relying solely on buffing without filing can leave the nails lacking in defined shape, which is important for both aesthetics and the overall durability of the acrylic application.
