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.
