A: There are few reasons why your nail polish chips, First, could be that your nail bed is weak and your actual nails are peeling so the nail polish on the top most layer also starts peeling with it. The best way to solve this problem is to put nail hardener before you put your nail polish and that seals in any possible peeling that could occur. Second, could be because you have applied the nail polish over the cuticle, you'll start to notice that when your nails grow your polish starts to move away from the cuticles and it chips. Third, when there is oil residue on your nails, the nail polish doesn't stick to the nail bed and you can experience chipping. So before every application, make sure to wipe your nails with an alcohol wipe. Fourth, we have noticed that people soak their hands or wash their hands which expands your nail bed and then apply nail polish. Once your nail bed contracts, nail polish can chip. If you keep these 4 things in mind, you should be able to have a long lasting manicure.
