ELI5: Why does showerheads start dripping 10+ minutes after being used?

Basically some time after having the shower, 10+ minutes after, the showerhead starts dripping hard for some time like someone had opened the shower again for few seconds. Any clue why this happens?

So after you turn off the shower there is still water in the shower-head and the pipe. It’s held there by force of vacuum. Eventually some air leaks into it, and a big enough bubble of air detaches and goes up to the highest point of the system, disrupting the balance and freeing some water to fall out of the shower-head.
