Can I use it everyday? Or it's just once a week?

Hi there! Thank you for your question. Instant Nail Hardener can be used daily. The Diamond Strength can be used as a base coat under your favorite Sally Hansen polish or alone and applied daily. If you have any questions, please reach out to our team. You can give us a call at 1-800-953-5080, and we'll be happy to help.

Does this help for repairing your nails back to the natural nail after years acrylic nail damage? My nails are so thin and break and split from it.

It takes time for nails to recover from bed damage. This product 'may' help but not sure. You may need to email Sally Hansen thru their website to inquire about your question.

Do these products have a glossy finish?

Hi there! Thank you for your question. Our Sally Hansen Diamond Strength Nail Hardener does dry to a shiny finish. Although, our Miracle Serum is translucent and will soak into your nail and skin with no shiny finish. We hope this helps! If you have any additional questions, we invite you to reach out to our team at 1-800-953-5080. It would be our pleasure to assist you!

Can i use this under uv gel base coat and gel polish?

Hi there! Thank you for your question. We do not recommend using these products under gel nail polish as it may affect the performance or quality of each product. If you have any other questions, please reach out to our team. You can give us a call at 1-800-953-5080, and we'll be happy to help.
