So, after a recent sword hit to my thumb, my finger broke (I was wearing gloves, it is fine) and there was a new finger nail growing beneath it. It is going well and my old nail is almost falling off, just holding onto the skin with the last bit. Last week when I bended the nail too far it put stress on my skin and hurt, this week I was able to simply take it off without any harm after showering.
So my question is: how does it stick to the skin? Is it glued? Does it work with vacuum/low pressure? Simply friction?
(NSFW because of the description of my nail/finger)

The same way your skin sticks to your body?
