Which nail product helps to strengthen nails?

Nail hardeners are specifically designed to strengthen and protect the nails. These products often contain ingredients that provide a protective barrier, help prevent brittleness, and can significantly improve the overall resilience of the nails. They are formulated to penetrate the nail plate and enhance its structure, which is particularly beneficial for individuals with weak or fragile nails.

In contrast, a base coat serves as a foundation for nail polish and may help to protect the natural nail from staining, but its primary function is not to strengthen the nail itself. Nail polish remover, on the other hand, is used to remove nail polish and does not contribute to the strength or health of the nails. Cuticle oil focuses on moisturizing and nourishing the cuticles and surrounding skin, rather than strengthening the nails directly. Therefore, the choice of a nail hardener is the most appropriate answer for strengthening nails.
