My favorite product from a different company was discontinued ages ago and I have tried a variety of nail products in hopes of finding anything that will help my nails grow without breaking. This is the only product that even comes close to working. If your nails have ridges that you can't seem to get rid of or start to break across the nail below the white "free edge" and into the nail body (or plate), this product should help. I have yet to find anything that will keep my nails from getting those stupid lateral tears. Too bad what worked is no longer available. Feel free to leave a comment if you've found something that works. I've probably already tried it but I'm open to reasonable suggestions.
