FAQS

Can I use Si-Nails on top of nail polish or gel?

Si-Nails is not designed for use on top of a polish or a gel. It should always be applied directly to bare nails that are clean and dry.

How long do I need to use Si-Nails for?

Results can be seen from as little as 14 days. However, it depends on the condition of your nails before starting Si-Nails nail strengthening treatment. The condition of your nails will improve with extended use.

The first time I used Si-Nails, I didn’t see any product come out. How do I start using it correctly?

Before using Si-Nails for the first time, activate the click pen by pressing down on the click button at least 25 times, until the applicator is moistened. This will activate the flow and you will be able to start using Si-Nails correctly from then on. You only need to click 25 times at first application.
