I used to have hair about 1.5 inches long on my head. This weekend I decided to shave it all off ang get a #2 buzz. I noticed a slight improvement in my mood and clarity of thought. Maybe it is from cooler air reaching my head or because more sun reaches my scalp. Could anyone explain if there is any scientific basis for these effects?

kidding.
But really, I doubt it has any effect. Your body works very hard to keep your body temperate constant.

Maybe his real "greatest blunder" was growing his hair crazy.

IIRC, North Korean instituted a mandatory short-hair policy for alleged cognitive benefits you mention. The reasoning was that long hair uses more of the body's nutrients that are otherwise available to the brain.
Isn't hair already dead tissue? Your body would still use nutrients to make hair, but it was my understanding that beyond that hair was "maintenance free" as far as nutrients from the body go.

When you are outside, is your scalp the only part of your body exposed to the sun? + Vitamin D

Hair could increase brain temperature by acting as an insulator, and having a cooler brain could result in better cognition.
There must have been studies on this. Do people who wear a hat perform worse on a battery of cognitive tests than people who do not?
Also, do you live in a hot climate? I'd imagine there's an 'ideal brain temperature' where signals are met with the least impedance but the brain doesn't suffer from hypothermia.
