The process of regrowth is slow and usually takes 3 to 6 months. After a nail is removed, the nail bed and root are in a damaged state and growth is relatively slow at this time. Most nails start to grow slowly after 1 week, and can grow about 1 to 2 millimeters per week, usually in 3 to 6 months. Patients with a slow metabolism will have slower nail growth and it may take relatively longer. During the process of nail growth, patients should keep the nail wound hygienic and avoid contact with water before the wound heals. Normally, it is recommended to eat some light and easy to digest food, avoid eating spicy stimulation, greasy and cold food, so as not to aggravate the condition. Patients who have their nails pulled out and have localized pus and increased pain in the process of regrowth are advised to go to the hospital in a timely manner to avoid delaying the condition.
