It would keep growing. The roots are still alive so they'd keep producing hair.0THIS IS NOT RELEVANT ANYMORE

There is something known as a point of saturation for hair, and I believe nails as well. After it reaches a certain length, it stops growing. That's why for example, the hair on your arms isn't as long as the hair on your head.1THIS IS NOT RELEVANT ANYMORE
