Fashionable manicure is bad for your health

There is a layer of substance on the surface of the nail, like the enamel on the tooth, that protects it from corrosion. If you file off the surface of your nails, your fingers will lose their protective layer and lose their resistance to corrosion by acidic or alkaline substances. Frequent manicures will cause nails to break and turn yellow or black, which affects your health.
