Re: if you rip your natural fingernail out of the nailbed, does it grow back
It depends entirely on how badly you damaged the Matrix where the nail plate cells are born. The white half-moon at the base of the nail is the leading edge of the Matrix. If you ripped it enough so that the nail plate separated from the nail bed at the point of damage, it will not re-attach. Whatever portion of the Matrix was not damaged will continue to produce new nail plate cells whichwill push the damaged portion toward the free edge. Depending on your genetics for nail growth and the size of the nail plate, this can take from 3-6 months.it can take from 3-6 months for the nail plate to completely replace itself.
