What is commonly advised for maintaining nail health?

Regularly moisturizing the nails is a key practice for maintaining nail health. Just like skin, nails can become dry and brittle, leading to breakage and other issues. Applying moisturizer helps to hydrate the nail matrix and surrounding skin, promoting flexibility and preventing damage. Moisturized nails are also less likely to develop hangnails or other conditions that can arise from dryness. Proper hydration supports overall nail integrity, ensuring they remain strong and healthy.

The other options would not support nail health effectively; excessive filing can weaken the nails, avoiding trimming can lead to uneven growth and potential breakage, and wearing nail polish continuously may prevent the nails from breathing and could lead to discoloration or damage.
