## Questions & Answers

**Q: Can I use it everyday? Or it's just once a week?**
A: 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.

**Q: 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.**
A: 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.

**Q: Do these products have a glossy finish?**
A: 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!

### ⭐⭐⭐⭐⭐ Healthy nails
*by E***X on May 13, 2026*

After decades of using S&S, gel, acrylic, to do my nails they were in really bad shape. They were thin splitting cracking. I started using this back in January and I’ve had very, very good success. My nails are now very short still but they’re healthy looking.

### ⭐⭐⭐⭐⭐ Great polish
*by M***E on May 2, 2026*

I'm enjoying the nail polish set. It does harden your nails and makes them grow. Use both polish they work very good together. Thanks

### ⭐⭐⭐⭐⭐ I love these products!! Helped me stop biting my nails
*by S***H on July 31, 2024*

I am an obvious nail biter and let me tell you, this stuff helps!! I carry it everywhere. It dries super fast and makes my nails stronger. I do kind of bite it off (when I’m nervous instead of my nails) but immediately apply another layer and it dries within like a minute. It’s helped my nails grow a lot (I cut them down) but my nail beds even got longer?? I would recommend this to anyone it’s way better than nail polish and doesn’t look as bad if picked off.
