Eli5 How does caffeine dehydrate you?

We all know that caffeine dehydrated you but how does it exactly work? For instance. If I drink an energy drink and immediately follow that with water does the water get absorbed properly or is there some sort of caffeine window?

Caffeine doesn’t dehydrate you. It is a mild diuretic, meaning you pee more. But the liquid you are consuming still hydrates you more than you’re losing.
