FAQ
Our Frequently Asked Questions from our customers and community!
Can I apply the Keratin Booster under Green™ or Green Flash™ polish?
Yes, but it’s essential to cleanse the nail surface after the product has been absorbed to ensure optimal polish adhesion.
Can I use the Keratin Booster with a base coat?
The Keratin Booster should be applied on bare nails only. If you wish to use a base coat, apply it after the care, once the nail has been cleansed.
Can I use the Keratin Booster several times a year?
Yes, you can repeat the care several times a year. It’s recommended to take a break between each care and monitor your nail’s condition over time.
If I want to apply more treatment base coat, should I remove the old coat first?
When using a treatment base coat, there's no need to remove the previous coat.
