I know this isn't a very 'natural' or 'frugal' suggestion, but it will probably make one or your usual manicuresor pedicures last three times longer--thus saving frustration, time, and, of course, nail polish and remover. OPI has a wonderful product called ChipSkip that is applied first to the nails, before anything else. It is recommended that you then apply basecoat, but I skipped that and went straight to two coats of OPI polish, and then the base/top coat. I am convinced the ChipSkip worked wonders, because my pedicure has lasted long over a week, and still looks like it was applied yesterday. I have done the base coat/ 2 coats of polish/ top coat for a long time, but the pedicure never lasted more than five days.
