Most nail infections are caused by cutting the nails too short. The shorter the nails are cut, the more the new nails will stick to the flesh and the more likely they are to cause nail infections, creating a vicious circle. It is recommended that the correct way to cut nails is not to cut the sides too short, slightly longer than the nail bed, and then the new nails will not easily stick to the flesh. The sides of the nails should be cut round and blunt, not angular, not square and round. After clipping the nail, use a small file to round out the nail’s rough edges, this is one way to do it. You can also stuff cotton between the nail and the nail bed, through this method is not easy to produce nail fungus again.
