How long does it take for a purple, bruised nail to heal?

Recovery from a bruised and purple nail typically takes 2 to 4 weeks. If the bruise is extensive or the nail injury is severe, recovery may require 1 to 3 months. Seek prompt medical attention at a surgery or dermatology clinic if the nail becomes loose, severe pain occurs, or there is pus formation.

For mild bruising—limited to the nail edge or a small area, with no nail loosening—the body will gradually absorb the blood clot. As the nail grows, the discolored portion will slowly move toward the fingertip and usually disappear completely within 2 to 4 weeks, without significant discomfort.

If the bruise is large, involving the entire nail, or accompanied by separation of the nail from the nail bed, recovery time will be longer. The blood must first be absorbed before new nail tissue gradually replaces the damaged portion, a process that may take 1 to 3 months. During this period, it's important to protect the nail and avoid re-injury.

Daily care should include avoiding pressure or impact on the injured nail. Soaking the affected finger in warm water may help improve circulation. Do not attempt to puncture the nail to drain blood. Maintain a diet rich in protein and calcium to support nail repair, and monitor the nail regularly for any signs of complications.
