I've done Shellac/Gel manicure every two weeks for over a year by the same nail tech. They always last the whole two weeks. The only reason I don't go three or four weeks in between is because my nails grow crazy fast and I have outgrowth. The last two times I got them done, the polish peeled off within a week. First time it was a red color and then I tried a light pink and it still peeled. No problems before, what could be up?
