The primary purpose of nail hardeners is to strengthen weak or brittle nails. These products are formulated with specific ingredients that create a protective coating over the nail, helping to reinforce its structure and prevent breakage. This is especially beneficial for individuals whose nails tend to split or peel, as the hardener adds an extra layer of durability while also promoting healthier nail appearance over time.

While promoting nail growth may be a beneficial outcome of using certain nail care products, nail hardeners specifically focus on enhancing the strength of the nails rather than directly influencing growth rates. Similarly, enhancing nail color relates more to nail polishes or tints, which are not the primary function of nail hardeners. Lastly, softening cuticles is a task typically associated with cuticle oils or creams, not hardeners, which are primarily concerned with the condition and resilience of the nails themselves.
