Argan Oil or my trusty Rose Petal Salve. I file them nicely using my crystal file. I polish using a base and top coat at all times. I never wash or clean without my rubber gloves. I take calcium pills and eat loads of yogurt. They are growing but still kind of brittle - I have been cutting them short for so long I am not sure if I can do this! I have decided to take these supplements. You can buy from any health food store. Watch this space - will update later.
Has anyone else tried them - did they work for you pray tell?
