Sorry if there are any Sally Hansen product lovers but I have never used any Sally Hansen product that did what it was supposed to do or was worth the money paid for it. My nails have always peeled a lot. I use Nail Tek Foundation II (which I believe is similar to nailtiques) my polish and Seche Vite as a top coat. That works for me. My nails are not peeling now and are so much stronger. Once in a while I get a split in the middle of a nail and I use nail glue and a piece of a teabag to patch it until it grows out. Gently file your nails before every manicure to help strengthen them too. I use the very fine grit nail boards at Sally's. I can't believe how long and strong my nails are now! Sometimes I just use 2 coats of my Nail Tek foundation and put my Seche Vite top coat over that. Gives a natural but pretty look.The foundation is a ridge filler and it does fill in the mess of the peeling nails.
