If you haven't grown nails by the above methods, you should go to the hospital for "medical nail reconstruction" surgery. Doctors will use human skin tissue engineering to produce "medical artificial reconstructed nails" and put them on toenails to keep them growing and make the grown nails look more beautiful. General medical reconstructed nails can survive smoothly, and the appearance is very beautiful, very close to the original toenail. As for how much, I'm not sure. The charging standard of each hospital is different. This operation belongs to plastic surgery. It will be more expensive if you go to a private plastic surgery hospital. If you go to a public hospital, it will be quite cheap. You can consult and compare yourself.
