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.
Nail detaches partially or fully from the nail bed: known as onycholysis, it can be caused by a trauma or chemicals as well as certain skin conditions; it will not reattach and you'll need to wait for about six months for a fingernail to grow back fully or 18 months for a toenail.
