Are your fingernails brittle? Do they break easily? This could be from gel manicures or otherwise. No matter what it is from you can make your nails stronger by soaking them  in a mixture of 1/2 cup of beer (the silicone in it will increase collagen production to fortify your nails), 1/4 cup vegetable oil (to hydrate), and 1/4 cup apple cider vinegar (to ward off infections) for 15 minutes twice a week. Your nails will be so beautiful you’ll hate to cover them in polish!
