Can the beard be completely removed?

No, it can only last for a while, and it will grow like a "bald quail". It is recommended not to pull it out. If it were a man, it would have a beard. Don't care too much. If you have to cut it off, use a laser or scissors. Don't shave with a razor. It will grow faster. All that comes out like you is fluff. You can use bleach. Use it up.
