## Questions & Answers

**Q: is this item absorbed by the nail?**
A: Anything you put on your nail is likely "absorbed" !  I've used Nutranail Flex-Shield Nail Hardener over a year without any problems/side effects.! I'm super sensitive to a wide range of ingredients with NO PROBLEMS. It is the BEST nail hardener on the market!!!!
I use it as a BASE COAT & TOP COAT. MY MANICURES LAST EASILY UP TO 14 DAYS!!!!!!!!!!!!!!!!!!!!!!!

**Q: Can finger nail polish remover take it off?**
A: I think so. I don't remove it from my nails, I just polish over it

**Q: Can you use it as a top coat**
A: Yes, I always use two thin coats on top of my nail polish and I can usually go at least one week between polishing.

**Q: Does this have any shine or color to it? It’s for my husband’s nails, and I don’t think he would appreciate a nail polish look.**
A: It doesn't have any color there is a slight shine
