Review: This WORKS, my nails are strong and healthy! - This works better than anything else! This is not a polish. You need to Apply to clean, dry nails so the nails absorb the keratin. It takes 1 minute to dry. I have been using 3x a week and my nails have never been so healthy. I used to wear opi powder and gel nails, so my nails were wrecked when I began using this product. I do a lot with my hands, clean, create, scrub, garden. My nails have become so strong. I have tried everything and this is the best, worth every penny. Follow directions only apply to end of nail, moisturize cuticle with cream or oil for best results!! This is not sponsored.

### ⭐⭐⭐⭐⭐ BEST Nail Hardener I’ve Ever Used!

### ⭐⭐⭐⭐⭐ Best product on the market for nails
*by F***2 on December 12, 2023*

I have actually known about this product for about 30 years. I was introduced to it by a friend that worked in a salvage yard and had damage his thumb nail an this product helped repair it in just months.. if you have thin nails or use a lot of false, acrylic, or gel nails and your bed is damaged, you only need to use this product a few times to have strong healthy nails.. my only word of caution is this is like pure keratin so if you use to much your nail will become like glass and break easily. use it maybe once every two weeks till your nails are strong then stop for a few months.
