Nail Hardener is a long lasting strengthening treatment. It reinforces nail structure from the very first application. Use it alone, straight onto the natural nail. Or use it as a base coat under polish or LongWear. The transparent finish fits any service without changing the look. Glycolic Acid gently smooths the nail surface for a polished, even finish. It also preps the plate for better adhesion. Hexanal reinforces the keratin network inside the nail, boosting strength and fighting breakage. Together, they target the real cause of weak, splitting nails, not just the surface.

Good To Know

How do I use the Nail Hardener?
You can use it in two ways. As a standalone treatment, apply two coats directly to the natural nail twice a week and remove completely between applications. Or apply one coat as a base coat under your regular polish or LongWear. Both methods deliver the strengthening benefit.

Why do I need to remove the Nail Hardener between applications?
When using it as a standalone treatment, removing the product between applications keeps the nail plate clean so the actives can work with each fresh coat. Building up too many layers prevents proper absorption. If you use it as a base coat under polish, this step does not apply.

What makes the Nail Hardener different from a regular base coat?
A regular base coat sits on top of the nail and protects the surface. The Nail Hardener goes further: Hexanal reinforces the keratin network inside the nail and Glycolic Acid smooths the surface. The result is a nail that is genuinely stronger, not just coated.

How long does it take to see results?
The nail surface feels smoother from the first applications. For a visible improvement in strength and less breakage, consistent use over three to four weeks gives the best results. Twice-weekly use as a standalone treatment delivers faster progress than occasional use. How to treat my weak/breaking nails To treat weak and breaking nails, start by applying the Keratin Booster to the natural nail. Allow the product to be fully absorbed by the nail plate and dry completely before applying the Nail Hardener. Treat the cuticles with Vitamina cuticle oil.

How To Use

As a standalone strengthening treatment
● Prep. Start on clean, dry nails. Remove any existing product and push back the cuticles.
● Apply. Apply two coats directly to the natural nail, twice a week.
● Remove. Remove completely between applications before reapplying.

As a base coat under polish or LongWear
● Prep. Start on clean, dry nails. Use Pro Septic to degrease the nailplate.
● Apply. Apply one coat as a base coat and let it dry before applying polish or LongWear.
