Russian dolls redirects here. For the movie, see Russian Dolls (film). A matryoshka doll (Russian: Ð¼Ð°ÑÑÑÑÐºÐ°; IPA: [mÉËtrÊ²ÉµÊkÉ], matrÃ«Å¡ka), also known as a Russian nesting doll, or Russian doll, is a set of wooden dolls of decreasing size placed one inside another.
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.
If you are having an accident which causes the big toe nail to come off instantly, you might want to be cautious about some things to prevent more severe infection. A separated nail from the nail bed will not reattach. Instead, a new nail will grow back within a quite long time. A big toe nail, for instance, requires up to 12 months to regrow completely. This new nail might also be in a different shape from the separated one, as this nail grows after the nail bed is injured.
