Yuck! I lost my big toenail once and it took 4? months to grow back completely.
4 months is the average time it takes for a toenail to grow back in its enterity.
Fingernails grow about 4 times faster than toenails though.
No idea about the fake nail in salon thing...sounds weird!
anywhere from 1 month to 3months. I think I heard somewhere in school that nails or hair grows at 1/18 of an inch day, faster or slower for different races/body types/gender/background/environment. I did the same with my big toe.
It will take a few weeks to a month at least. You can call the nail salon and try.
