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.
An injury to a nail may result in the loss of the nail. As long as the nail bed itself wasn't damaged, a lost nail should eventually grow back. Healthy fingernails grow at a rate of about 0.10mm per day, but toenails are slower, growing at only about one half to one third of a fingernail's rate.
