It's not the coffee, it's the fact that many people drink everything _but_ water. Coffee's got a lot but you can't drink that much of it, so if that's all you drink, then you get dehydrated. People also drink too much soda which doesn't help, and people also just don't drink for long periods of time.
If you get headaches then try drinking some water. Pretty simple.
Also, man you're a giant douche. Did someone piss in your fucking coco puffs today little boy? Shit.
