Re: Do nails grow back when split?
It totally depends on how deep into the nail bed you cut. If the cut compromised the nail bed and it developes scar tissue, the nail will grow attached up to the scar, but not attached at the distal portion of the cut. I slammed my pinky in the car door and it cut into the nail bed quite deep on one side and the nail is only attached before the cut, not after it. My 'smile' line is crooked now.
