My nail fall off my finger, how long does it takes to come out again?
about 3 weeks . i worked in a chicken processing plant and our thumbs nails would come off and it would always take 2 to 3 weeks for them to grow back .
My also fall off when i hit my leg on my exercise machine and when it grow back it was not the same,let say it will come out around 2 to 3 weeks.
A nail can take 2-4 months to grow back completely. However, you should try to increase your metabolic rate. To increase metabolism, do a lot of exercises, drink a lot of water and eat healthy.
