      No. The skin will grow back to a certain extent.

      The top layers of skin are essentially dead tissue, so they continually are shed and lost then replaced. If you injure yourself and it effects the top layers of skin, then the fingerprint will come back as the dead tissue is replaced with the next layer.

      If you injure yourself really badly where most of the skin is removed, then the fingerprints will not come back – you are left with a scar.

      Don’t believe what you see in movies like Men in Black!

      It’s pretty difficult to remove fingerprints – Technology isn’t smart enough to beat evolution just yet!
