Nails that have all fallen off can be caused by external forces, infection, and other factors. As long as the nail matrix and nail bed are not affected, the nail can usually grow back.
1. External force: Nails falling off may be caused by external force, such as nails being smashed or squeezed by a door, which may lead to nails being damaged, deformed or falling off. As long as there is no damage to the nail matrix and nail bed, the nail may grow back gradually over time.
2. Infection: Nails falling off can also be considered to be related to fungal infection. Fungus invades the nail plate and nail bed, resulting in changes in nail color, texture and shape. Fungal infections are treated with antifungal drugs such as ketoconazole, miconazole nitrate, bifonazole and itraconazole. Nails can usually grow back after standardized treatment.
After the nails fall off, it is recommended to go to the dermatology department of the hospital for examination in time and follow the doctor’s instructions for standardized treatment.
