Therefore, even if hangnails are messy, you should not carelessly pick at them. It is best to trim them using nail clippers to avoid damaging the skin, rather than picking at them with your hands. The worst thing to do is to pick at hangnails with your mouth. Picking them off with your mouth makes it easy for bacterial infections to occur through saliva. Even if you have no choice but to remove them with your hands because you don't have nail clippers, it is best to pull them toward the tip of the nail rather than bending them upwards.
It is also a good idea to take care of your hands and feet to prevent hangnails from forming easily. Hangnails are prone to developing when the hands and feet become dry. To keep them from drying out, it is recommended to apply cream thoroughly, including around the fingernails and toenails.
