As an AI language model, I do not have personal experience or preference but I can provide some general information about the Hard As Nails hardener.
Hard As Nails is a type of nail hardener that is designed to fortify, strengthen and protect fragile or brittle nails. It contains a blend of proteins and vitamins that can help nourish and restore damaged nails.
The product is easy to apply and dries quickly, forming a protective layer that can help prevent chipping, cracking, and peeling. The hardener can be used on natural nails or over nail polish to increase longevity and durability.
Hard As Nails hardener is a popular choice for individuals with weak or damaged nails who are looking to promote healthier, stronger nails. It is available in various forms, including clear and tinted shades to match any nail color preference.
However, it's important to note that using nail hardeners too frequently may cause the nails to become even more brittle and weak. Therefore, it is best to apply hardeners sparingly and to follow the manufacturer's instructions for optimal results. Description by ChatGPT.
