my nails grow long but i have vertical ridges. i wanted a product that would moisturize and "feed" my nails. i like this product. when my nails are bare i'll use this for several days in a row and it seems to help. it's not like a traditional polish. it's liquidy and stays that way for awhile but dries down and when it does it doesn't look like you have anything on your nails at all. it can be used as the first coat but i typically use it when i'm not polishing a color or anything. it really is like medicine to your nails and when your nails are in bad shape sometimes you have to forego polish to treat them. this product does that.
