Hardener polish is specifically designed to enhance the strength and durability of the natural nails. Its primary function is to incorporate tiny fibers or other strengthening agents that bond to the surface of the nails. This added protection helps reduce the likelihood of nail breakage and improves overall nail integrity. By reinforcing the nail plate, hardener polish aids in achieving healthier nails, especially for those that are prone to peeling or splitting.

While adding shine to nails is a common feature of many polishes, that is not the main purpose of hardener polish. Similarly, the function of strengthening the nail bed itself is more related to nail bed health rather than the polish applied to the top of the nails. Removing nail polish is obviously not related to the purpose of hardener polish, which is to enhance the nails' structure and resilience.
