I went in for a shellac manicure and I'm pretty picky but it turned out great. However now, two months later, it will not come off!!! I tried soaking it in acetone, the proper way to remove shellac, and it sat for AN HOUR and they won't budge. So a warning to you all, if they use a drill to remove shellac, it means they are adding something into the polish to make it stay so that there's no possible way to get it off without damaging your nails! Will never come back, who knows what they are putting into the polish.
