no. the rate of fingernail growth will not change/accelerate if the other nail is removed. as a matter of fact the old nail can help protect the very sensitive nail bed as the new nail gradually grows out again.
will a fingernail grow back faster if the old nail is completely removed? . the bottom part of my nail came off the other day previously when this has happened removing the rest of the nail relieved the pressure of the puffed skin and lessened the overall pain. is it better to take the whole nail off and allow the new one room to grow?
