The Sally Hansen Diamond Strength Nail Hardener aims to strengthen nails in just five days. As a type of repair, it focuses on preventing brittleness and protecting nails from splitting, cracking, and tearing. This makes it ideal for individuals facing frequent nail breakage. One of its notable ingredients is that it is formaldehyde-free, which is a plus for those who prefer less harsh chemicals in their beauty products.

The product is designed for ease of use, being in serum form and applied like clear nail polish, making it user-friendly even for those who are not nail care experts. Durability is another key feature, with the hardener claiming to protect nails for up to 10 days, which can be very beneficial for maintaining nail health over a longer period. Additionally, the product also smooths cuticles, adding to its benefits.

However, at 15 milliliters, the liquid volume might seem small for those looking for a long-term solution, and repeated purchases may be necessary. Its protective layer is clear, which might not appeal to users looking for a colored polish. In summary, this nail hardener is best suited for individuals seeking a quick and effective way to strengthen and protect their nails, while also preferring a clear and easy-to-apply solution.

In terms of durability, the kit is effective for temporary fixes but may not substitute long-term professional care.
