Nail injuries can be noticeable until the damaged nail grows out. Fingernails usually regrow completely in about two months. Toenails take about four months. If injury includes the base of the nail, some cosmetic changes may be permanent.
Nails grow faster in the summer than in the winter. White spots on your nails don't indicate a calcium deficiency. Finger and toenails grow at an average rate of 3 millimeters a month. Fingernails take 3 to 6 months to regrow completely, while toenails require around 12 to 18 months to grow back fully.
