I was given this product in exchange for my honest review. My nails have been so brittle lately, but after using this, they feel noticeably stronger. It's super easy to apply, just a few drops, and it soaks in quickly. I love that it doesn't leave any sticky residue, and my nails look healthier and shinier. I've been using it consistently, and I've noticed a difference in how much less my nails are breaking. It’s like a little spa treatment for my nails at home.
