This product WORKS. Gel polish destroyed my nails, and I have been struggling with cracking and splitting nails for a year since I stopped using it. I've tried oiling my nails, wearing gloves whenever I'm washing dishes, applying several different brands of nail strengtheners with no improvement. I have been using Kapa Nui nail repair and strengthener for 18 days now and my nails have shown remarkable improvement. Spots on my nails that I was sure would split have not, my nails are actually growing and they feel stronger. I am so pleased with this product!!
