ok, this product takes some getting used to, but it's worth it. if used as a basecoat, WITH A RIDGEFILLER, it really does seem to keep my nails from splitting and breaking as they are wont to do. i use this with nail armor, one coat of colored polish, and the won't chip, and my manicure lasts nearly twice as long as it does without all the prep work. anyway, this treatment has tiny little fibers in it, which are supposed to help strengthen your nails. if you try to apply polish without ridgefiller though, the polish will get all gummed up in the fibers, and make an awful mess. this can also be used with just the ridgefiller for a nude look, when i don't have time for a manicure but don't want my nails to start splitting and breaking again. good shtuff!
