Which product can help improve the appearance of natural nails?

A nail strengthener is specifically formulated to enhance the health and appearance of natural nails. These products often contain ingredients that help to fortify the nails, making them less prone to breakage and improving their overall texture and shine. By utilizing a nail strengthener, individuals can encourage healthier nail growth and may also see improvements in the thickness and durability of their nails.

While other options like nail glue, top coats, and base coats serve distinct purposes, they do not directly address the enhancement of the natural nail's appearance in the same way that a strengthener does. Nail glue is used to bond artificial nails or nail tips, while a top coat provides a protective layer and adds shine after a manicure. A base coat is applied before the nail polish to protect the nail and improve polish adhesion, but it does not bolster the nail's inherent strength or health. Thus, the nail strengthener is uniquely effective for those looking to improve their natural nails.
