Which serves to provide additional protection for the natural nails?

Nail enhancements such as acrylics or gels function to provide an additional layer of protection over natural nails. These enhancements not only enhance the appearance of the nails but also bolster their durability and resistance to breakage. When applied correctly, they create a hard surface that shields the natural nail from everyday wear and potential damage.

While base coats and top coats do contribute to the health and longevity of nail polish and can help prevent staining or chipping, their primary role is not to serve as a protective barrier for the natural nail itself, but rather to protect the colored polish on top. Nail strengtheners aim to improve the integrity of the natural nail by hardening it and preventing breakage, yet they typically do not provide the same level of external protection as acrylics or gels. Similarly, regular manicures offer benefits in terms of cleanliness and aesthetic appeal, but they may not substantially enhance the strength or protection of the nails compared to the robust shield that enhancements provide.
