Yes had the headache and exhaustion too.
It took 4 days to get rid of the headache and I could feel the pounding in my head when I squatted again.
And it took couple weeks of agony to find out what happend:
Wrong breathing pattern during heavy lifting.
I was holding my breath during the lift.
This is something I adopted from doing deadlifts. To keep my upper body strainght I hold my breath and as I can’t just drop the weight on the floor I exhale at knee level.
Some how this way of breathing got carried over to heavy squats.
So my solution was to consciously learn a new breathing pattern.
The headache also appeared during bench press, so I learned to breath and keep tension where it’s needed during the lift.
I really thought of quit lifting because after the first big headache it appeared all the time even with other lifts.
So my advice is to check if your holding breath during the lift!
I have this problem, too, and also attribute it to not getting enough oxygen to the brain while squatting. Mostly, I’ve just learned to deal with it. It doesn’t last long after finishing the set.
However, if I understand you right, you are recommending breathing during a squat rep. That sounds like a terrible idea. If I let out my air at the bottom of the squat, my squat goes down and my risk of injury goes way up. I definitely try to take a couple breaths at the top, but that has to be balanced with the fact that the faster I squat, the faster the set is over and the faster I can breath normally again.

Maybe I didn’t make the picture clear enough: I don’t keep breathing throughout the set, I just learned to breath at different “landmarks”.
I used take a big breath and keep the air in from squatting down and back up to lock-out. I would then take the needed breaths for the next rep.
And I don’t thinks its an oxygen issue, I think its blood pressure. Not enough oxygen would cause you to pass out.
What I do now is this:
I fill my lungs, squat down and as I rise I exhale. Very controlled. This is about 2/3 of the up movement. To get out the hole you want to the tension in your upper body or else you would simply collapse on heavy weights.
Maybe you wanna try that with a light weight, as your warm up sets to get used to that new pattern. Do it very consciously and feel the point where to exhale. I know that sounds sloppy. Try to use the pain as a gauge.
When I felt it build up again I started to let the air out.
Thats what helped me.
