This 2-in-1 nail strengthener & base coat provides both basecoat adhesion and strengthening treatment properties, which promote nail growth, stronger nails and longer lasting manicures. Making your nail polish last is simple. The key is clean, prepped nails and proper application. May be applied on its own or as a base coat with polish over it. 

Application:Apply one coat of nail strengthener/base coat on clean and dry nails. May be used as strengthener only or doubled as basecoat. If using as strengthener only, use 2-3 times per week for two weeks. Remove and reapply original application.

    Firm Foundation rocks!

    I've almost completed my first 2 week round of using Firm Foundation, and I'm so pleased! It is actually working on my weak nails and strengthening them.
