Nails that are too short can lead to peri-nail skin damage, onychomycosis and other hazards. 1. Nail skin damage: If you cut your nails too short, the skin around your nails will be unprotected, and then the phenomenon of growing barbs will occur. Not only that, the extension of the nail trimming can also cause discomfort. 2. Inguinitis: If the nails are trimmed too short, it may cause ingrown nails, or because the nail bed is slightly damaged, thus appearing the symptoms of onychomycosis, which will destroy the normal skin barrier around the nails and cause bacterial invasion, thus appearing localized infection, and then cause the symptoms of onychomycosis. Therefore, the general situation of too short nails is not conducive to the health of the body, so it is necessary to do a good job of relative protection, pay more attention to the cleanliness of the hands.
