I love Essie, but OPI is good too. Like Vrai said, use a base coat, which will help remedy the stain. Soak nails in lemon juice for a few minutes, of if you're impatient like me, use bleach. Just for a few seconds though. Wash hands, and use Emu oil. Let nails breathe between polishing. Take vitamins that might stop the peeling. Hair, Skin, & Nails is a good one that can be found at most vitamin sections of the store. Prenatal vitamins are good too.
